Huanghe Whirlwind: Launching R&D in Diamond Applications for Semiconductors, Functional Materials, and Beyond

Release date:

2025-07-16

July 14, Yellow River Whirlwind Announcing the earnings forecast for the first half of 2025: net profit attributable to shareholders is expected to be a loss of RMB 285 million, while the adjusted net loss—excluding non-recurring gains and losses—is projected at RMB 286 million.

Compared to the loss of 248 million yuan in the same period last year, Huanghe Xuanfeng’s losses have widened again. The company has now reported losses for two consecutive years, with deficits of 798 million yuan and 983 million yuan in 2023 and 2024, respectively.

The company stated in its announcement, Ultra-hard materials Intense industry competition, combined with weak downstream demand, has kept product market prices in a prolonged slump—similar to last year's trend. Recently, product selling prices have remained stubbornly low despite the company implementing certain cost-optimization measures this year. However, weighed down by challenging market conditions, these efforts have failed to reverse the declining business performance, resulting in an operating loss for the first half of 2025.

Publicly available information shows that Huanghe Whirlwind primarily operates in products including superhard materials and products, as well as superhard composite materials and items—mainly for industrial use. Diamond , Cultivate Diamonds 、 Grinding wheel 、 Cutting tools Drill bit, Saw blade Etc.

Behind the losses, other financial indicators also paint a grim picture. As of the first quarter of 2025, the company’s asset-to-liability ratio had already reached 82.6%, and its net cash flow from operating activities turned negative.

Due to the ongoing decline in lab-grown diamond prices, Huanghe Xuanfeng had previously turned its attention toward the semiconductor industry. The company previously stated that it would continue to focus on its core business of ultra-hard materials, expanding production capacity around its existing diamond and diamond-based product applications while also pursuing research and development into new areas—such as third-generation semiconductors, nanomaterials, and functional materials—where diamond materials can be applied.

Zhongzhi New Materials has applied for a patent on an epoxy resin-bonded diamond grinding block and its manufacturing process, which boasts high versatility.

Pore-Size Control in Porous Magnesium Rings and Its Impact

As a functional material, the performance of porous magnesium rings is closely tied to their internal pore structure. Porosity, a key parameter that measures the proportion of void space within the material, directly influences the material’s physicochemical properties and determines its suitability for various practical applications. By carefully controlling porosity, it’s possible to achieve targeted optimization of material performance to meet specific requirements. From a mechanical perspective, changes in porosity alter the material’s density distribution and load-bearing capacity. Higher porosity reduces the apparent density, leading to lighter overall weight—but it may also compromise compressive strength. This characteristic makes such materials particularly valuable in applications where lightweight design is critical. However, in scenarios involving significant mechanical loads, maintaining structural integrity requires precise control over pore size and distribution. On the functional level, porosity creates a network of pathways that facilitate efficient mass transfer. Increasing porosity appropriately can enhance a material’s adsorption capacity and permeability, making it ideal for applications like filtration or as a catalyst support. Meanwhile, the presence of interconnected pores promotes rapid diffusion of electrolytes or reaction media, which is crucial for improving the performance of electrochemical devices. On the downside, excessively high porosity might weaken the material’s corrosion resistance, potentially leading to localized corrosion issues, especially in humid environments. Ultimately, the choice of fabrication process plays a pivotal role in precisely tuning the porosity of these materials.

Storage precautions for porous magnesium rings

Porous magnesium rings, as a special type of metallic material, are widely used in industries and medical fields. Due to their unique physical structure and chemical properties, careful attention must be paid to environmental conditions during storage to ensure that the material’s performance remains unaffected. **Storage Environment Requirements:** Porous magnesium rings have stringent requirements for their storage environment, particularly regarding factors such as humidity, temperature, and exposure to light. The relative humidity in the storage area should be kept below 65%, and materials should never be stored outdoors or allowed to come into direct contact with rainwater or dew. If the warehouse floor is concrete, it’s essential to lay down a moisture-proof cushion layer to prevent ground moisture from seeping into the material. In terms of temperature, it’s recommended to maintain conditions between -5°C and 35°C, avoiding prolonged exposure to high temperatures (above 40°C) or extreme cold combined with freezing-thawing cycles (below -10°C). High temperatures can accelerate the aging of the surface oxide layer, while low temperatures paired with moisture may lead to condensation or even ice formation on the surface, potentially causing corrosion once melted. Additionally, the warehouse should be well-ventilated naturally, but avoid exposing the material to strong, direct winds. Direct sunlight should also be avoided. If temporary outdoor storage is unavoidable for up to 72 hours, the material must be carefully covered with a double layer of shade cloth and waterproof tarpaulin. **Moisture-Proof and Corrosion-Resistant Measures:** Moisture protection is critical when storing porous magnesium rings. Use tightly sealed packaging materials during storage, and regularly inspect containers to ensure they remain airtight and free from leaks or damage. After opening previously used packaging, promptly reseal it to maintain its protective integrity.

Process for Preparing Porous Magnesium Rings and Performance Optimization

Porous magnesium rings, as a bio-material with a unique structural design, have demonstrated significant application potential in both medical and industrial fields. Currently, optimizing their preparation processes and enhancing their performance have become key research directions in materials science. Among the fabrication techniques, powder metallurgy is currently one of the most widely used approaches. This method involves mixing magnesium powder with pore-forming agents, followed by compression molding and sintering to create the desired porous structure. Crucial process parameters, such as sintering temperature and duration, directly influence the material’s porosity and mechanical strength. Another popular method is the template-based approach, which utilizes removable template materials to precisely define the pre-designed pore architecture, allowing for more accurate control over pore size distribution. Additionally, the integration of 3D printing technology has opened up new possibilities for producing complex-structured porous magnesium rings, enabling customized pore designs through layer-by-layer additive manufacturing. Performance optimization primarily focuses on three key dimensions. First, structural characteristics are carefully tuned by adjusting the ratio and particle size of the pore-forming agents, resulting in a wide range of porosities—from 20% to 80%—with typical pore sizes ranging between 100 and 500 microns. This highly controllable porous structure not only ensures lightweight properties but also lays a solid foundation for advanced functional applications. Second, mechanical performance is significantly improved by incorporating appropriate alloy elements or employing hot isostatic pressing, boosting compressive strength to levels suitable for medical implant applications.
