晶圆加工用绿碳化硅JIS2000#电导率低杂质少
晶圆加工用绿碳化硅JIS2000#电导率低杂质少广泛用于金属、有色金属、硬质合金、大理石花岗岩、玉石的研磨。水流分级的工艺使得绿碳化硅具有更高的纯度和清洁度 。水洗后PH值呈中性，电导率低，无酸碱残留，粒型有尖锐型和圆整型。
Green silicon carbide 2000 # is widely used for grinding metals, non-ferrous metals, hard alloys, marble, granite, and jade. The process of water flow suspension treatment enables green silicon carbide to have higher purity and cleanliness. After washing, the pH value is neutral, the conductivity is low, there is no acid or alkali residue, and the particle size can be sharp or round.
