Anyang Zhengzhao Metallurgical Refractory Co., Ltd. is a leading manufacturer of Fine Powder Silicon Carbide (SiC), engineered to meet rigorous industrial demands for high-temperature stability, wear resistance, and chemical inertness. With SiC content ≥98% and customizable particle sizes ranging from 260 to 325 mesh, our product is optimized for applications in refractories, photovoltaics, abrasives, and advanced composites. Unlike generic alternatives, our powder undergoes multi-stage purification to ensure minimal impurities (<0.5% free carbon), making it ideal for precision-driven industries.
Our proprietary production process combines electric arc furnace synthesis and air classification technology, enabling granular control over particle distribution (D50/D90/D97). This ensures seamless integration into ceramic matrices, anti-corrosion coatings, and semiconductor polishing slurries. By addressing critical challenges like thermal shock resistance and oxidation-induced degradation, we empower clients to enhance equipment longevity and operational efficiency.

The advantages of high carbon silicon deoxidation:
High carbon silicon contains the element silicon. Once high-carbon silicon is added in the steelmaking process, the silicon element contained in it interacts with oxygen to deoxidize the oxygen in the molten steel to increase the hardness and quality of the steel. The silicon element of high carbon silicon and oxygen have a good affinity, so the molten steel always has the characteristic of not splashing after being put into it.
The advantages of HC silicon slag collection:
High carbon silicon also has the advantage of collecting slag. Adding a certain proportion of high carbon silicon into the molten steel can make the oxides in the steelmaking process quickly agglomerate, which is convenient for filtration processing, makes molten steel purer and significantly improves the density and hardness of the steel.
The advantages of high carbon silicon to increase furnace temperature:
High carbon silicon is a material that resists temperature well. Using a silicon-carbon alloy in the steelmaking process can increase the furnace temperature, increase the conversion rate of the ferroalloy, and accelerate the reaction speed of the molten steel and elements.
High carbon silicon allows many manufacturers to save costs:
Today, ferroalloy materials are more expensive. As a new type of metallurgical material, silicon-carbon alloy is favored by many manufacturers because of its lower price than traditional metallurgical materials. High-carbon silicon can replace expensive metallurgical materials such as ferrosilicon and achieve unexpected results. The results being satisfactory, the use of the silicon-carbon alloy allows manufacturers to reduce their costs and increase their profits.
