Quality Control
We strictly detect the raw materials. We not only the silicon powder in the item of general iron, aluminum and calcium, but also set strict standards for boron, phosphor, carbon, and oxygen; for potassium chloride, our company imports Potassium(K) which is only used for electrolysis from Germany. This will effectively decrease the quantity of impurity hedonism. Based on this strict raw material checking, the highly effective fractionation system of Trichlorosilane, advanced electro analysis equipment of Potassium Hydroxide and fully furnished analysis equipment together insure the good quality.
