THALLIUM(I) CARBONATE Structural

What is THALLIUM(I) CARBONATE?

Chemical properties

colourless crystals or white powder

The Uses of THALLIUM(I) CARBONATE

manufacture of imitation diamonds.

The Uses of THALLIUM(I) CARBONATE

Thallium carbonate (Tl2CO3) is used to make artificial diamonds (along with several other thallium compounds).

General Description

Heavy, shiny, colorless or white crystals. Used in the manufacture of imitation diamonds. Also used in analysis to test for carbon disulfide and as a fungicide.

Reactivity Profile

THALLIUM(I) CARBONATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Thallium is a digestive tract irritant and nervous system toxicant. It is classified as extremely toxic. Probable oral lethal dose (humans) is 5-50 mg/kg, or between 7 drops and 1 teaspoon for 70 kg person (150 lb.). Teratogenic effects are noted after chronic intoxication.

Fire Hazard

When heated to decomposition, THALLIUM(I) CARBONATE emits toxic fumes of thallium. (Non-Specific -- Thallium Salts, n.o.s.) Fire may produce irritating or poisonous gases.

Safety Profile

Poison by ingestion, skin contact, and subcutaneous routes. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of T1. See also THALLIUM COMPOUNDS.

Purification Methods

It crystallises from hot water (4mL/g) on cooling. POISONOUS.
