Description

Calcium grains react with H at temperatures above 400°C to slowly generate calcium hydride. At room temperature, the reaction with water is moderate, and a calcium hydroxide protective film is formed. When heated, it reacts violently with water to release H₂. The chemical properties of calcium in calcium grains are very active, have strong reducing ability, and are easy to combine with halogen, sulfur, nitrogen, etc.

Preparation method of calcium grains:

Reduction method: Limestone is usually used as raw material, calcined into calcium oxide, and aluminum powder is used as a reducing agent. After pulverization, it is mixed in proportion and pressed into blocks, and reacted under vacuum and temperature to generate calcium vapor and calcium aluminate, which are reduced to crystals. Calcium is melted and cast into ingots to obtain calcium ingots.
