Overview and Standards of Silicon Carbide Micropowder

It refers to micron‑scale silicon carbide powder produced using JZFZ equipment for ultrafine grinding and classification. Silicon carbide micropowders are primarily available in 1200# and 1500# grades. As these powders are mainly used in the abrasive industry, they must meet stringent grading requirements: no large particles are allowed. To comply with both international and domestic standards, manufacturers typically employ JZF classification equipment for high‑precision sizing. In China, the main types of silicon carbide micropowder are black silicon carbide and green silicon carbide. The principal standards for silicon carbide micropowders include Chinese, Japanese, and European specifications; among these, Chinese and Japanese standards dominate the domestic market, while Japanese standards are predominant for exports.

Future Development Prospects of Silicon Carbide

Silicon carbide boasts an exceptionally broad range of applications, finding extensive use in abrasives, the chemical industry, metallurgy, ceramics, and more. Different sectors have varying requirements for silicon carbide particle size, necessitating a series of processing steps—such as crushing, acid–alkali washing, magnetic separation, screening, or water‑based classification—to produce products of specific gradations that meet diverse industrial needs. Sand-making machines are well suited for crushing and shaping soft, medium‑hard, and extremely hard materials, and are widely employed in processing various ores, cement, refractory materials, alumina clinker, carborundum, glass raw materials, manufactured construction sand, stone aggregates, and a variety of metallurgical slag. They particularly excel in handling high‑hardness, ultra‑hard, and highly wear‑resistant materials such as silicon carbide, brown fused alumina, sintered aluminous clay, and abrasive sands, delivering higher throughput and efficiency compared to other types of crushers. As the applications of silicon carbide continue to expand, it has become an essential engineering material in the solar photovoltaic, semiconductor, and piezoelectric crystal industries. With conventional mineral energy resources steadily dwindling, the photovoltaic sector—led by solar cells—has experienced rapid growth. Silicon carbide serves as a specialized material in the upstream segment of the photovoltaic value chain, specifically in the production of crystalline silicon wafers. Driven by the expansion of the photovoltaic industry, the silicon carbide market is gaining new opportunities through product‑structure upgrades and growing downstream demand. With continuous advancements in sand‑making equipment technology, silicon carbide’s already wide array of uses is further spurring the development of novel applications and emerging markets. At the same time, the evolution of silicon carbide and the progress of sand‑making machinery reinforce each other: the expanding scope of silicon carbide’s applications demands ever‑higher technical performance from its production equipment, enabling it to fully realize its intrinsic value. Consequently, the increasing versatility of silicon carbide is propelling the advancement of sand‑making technology.
