29689-14-3 - Introduction
chromium carbonate is an inorganic compound with the chemical formula CrCo3. The following is a description of the nature, use, formulation and safety information of chromium carbonate:
Nature:
1. Appearance: chromium carbonate is a green solid, commonly found in nature in chromium minerals.
2. Solubility: It is insoluble in water, but soluble in acid.
3. Stability: At high temperatures, chromium carbonate will decompose into chromium oxide and carbon dioxide.
Use:
1. Industrial applications: chromium carbonate can be used as pigments and dyes, widely used in paints, coatings, ceramics and textiles.
2. chromium salt preparation: chromium carbonate is an important raw material for the preparation of other chromium salts, such as ammonium chromate and sodium chromate.
Preparation Method:
chromium carbonate is prepared by two main methods:
1. Chemical precipitation method: chromic acid or other chromium-containing compounds react with carbonate salt to generate chromium carbonate precipitate, and then obtain chromium carbonate with high purity through filtration and drying.
2. Ammonium bicarbonate reduction method: chromium carbonate solution reacts with ammonium bicarbonate to produce chromium carbonate precipitate.
Safety Information:
1. chromium carbonate has low toxicity to human body, but it is still necessary to comply with the safety operation procedures of general chemicals.
2. During operation, avoid inhaling dust and avoid contact with skin and eyes. If there is contact, rinse immediately with plenty of water.
3. Waste should be stored and disposed of properly and in accordance with local codes and regulations.
