1、Chemical Name: Potassium Bisulfate
2、Molecular Formula: KHSO4
3、Molecular Weight: 136.16
4、CAS: 7646-93-7
5、Character: White flake or granular crystals. Easy to moisture absorption. It breaks down in ethanol. It loses water at high temperatures and tends to become pyrosulfates. Relative density 2.24.Melting point is 197 ℃. Low toxicity, corrosive.
6、Usage: It is used as a disintegrating agent of minerals and flux for silicon compounds.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage & Transportation: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
