Application:
Stable at room temperature and pressure Avoid material oxides. It can be melted into a yellow transparent liquid by heating, and solidified into a white block with crystalline cracks by cooling. Decomposition occurs at higher temperatures. The solution of zinc sulfate and the solution of potassium selenite are mixed to produce a white amorphous precipitate. The precipitate is heated with a small amount of selenite and can be transformed into a fine crystalline powder, which is the crystallization of zinc selenite monohydrate ZnSeO3·H2O. This hydrated salt is stable in air and heated to 100 ° C. The crystallization of anhydrous zinc selenite can be obtained by heating the monohydrate with a solution of selenite with a concentration of 52.86%. Zinc selenite dihydrate ZnSeO3·2H2O can also be crystallized from the acidic solution of zinc selenite. This hydrated salt is heated to 200 ° C to produce anhydrous zinc selenite.
