Nature Description:
Yellow or brown powder, insoluble in water and weak acid, can be dissolved in concentrated acid to produce the corresponding salt.
Packaging: 1000 kg / bag, neutral packing, also according to customer requirements for packaging.

Application:

1. Glass (TV glass) glass industry used to do a bleaching agent and clarifying agent.
2. For the preparation of the car in the chemical industry autocatalyst, PVC stabilizers.
3. Also for the synthesis of naphthalene cerous do paint driers.
