Recent developments in green silicon carbide

Green silicon carbide as an abrasive, silicon carbide production area in our previous two or three decades was a hero, and later as for export purposes and silicon carbide grinding non-development, production volume relative to the black silicon carbide, gradually relegated secondary position.
But its total production is always rising steadily, especially in the late 1990s, the international wire cutting of green silicon carbide powder application process, our green silicon carbide production and exports have increased, but producing regions and manufacturers also limited to the traditional Northeast Mudanjiang, Hun, etc., the Central Plains, Zhengzhou, Pingdingshan, Shandong Tengzhou, linshu and Hubei Danjiangkou, etc., the Northwest Territories and only Qinghai Guide Haiyan and Blackforge change Green furnace of LAI.
Another turn of the century before, not on the use of Sichuan power grid small hydro electricity low (from the 0.08 to 0.15 yuan / KWH), from Shandong, and Fujian in Lianyungang Miannig, ganluo and Johnson and Yaan, etc., to build a batch furnace capacity 6300KVA ~ 2000KVA green silicon carbide smelter home.
So far, China's annual output of green silicon carbide by the reform and opening up to the time of less than three tonnes to seven or eight tons. But the biggest single furnace capacity still hovering at 5000 ~ 6300KVA, smelting process also follows the formation of the sixties and the East China Sea petroleum coke calcination quartz sand as raw material processes.
