Silicon Carbide Manufacturers
There are over 200 state-owned silicon carbide smelting enterprises in China, with an annual production capacity of more than 2.2 million tons (including over 1.2 million tons of green silicon carbide blocks and about 1 million tons of black silicon carbide blocks). Most smelting transformers have a power rating of 6300~12500kVA, with the largest being 32000kVA. There are over 300 processing enterprises for producing grits and micro powders, with an annual production capacity of over 2 million tons. In 2012, the capacity utilization rate of China's silicon carbide was less than 45%. About one-third of the smelting enterprises have production lines for processing grits and micro powders. The silicon carbide processing enterprises for grits and micro powders are mainly distributed in Henan, Shandong, Jiangsu, Jilin, Heilongjiang and other provinces.
China's silicon carbide smelting production technology, technical equipment, and energy consumption per ton have reached the world's leading level. The quality level of black and green silicon carbide raw blocks is also world-class. The gap between China's silicon carbide and the world's advanced level is mainly concentrated in four aspects: first, in the production process
