Thallium Hydroxide Industrial Grade 99.9%

Thallium hydroxide is white needlelike crystalline particle or powder, which is a thallium salt. It changes to yellow in air and reacts with carbon dioxide in air that form thallium(I) carbonate. Thallium(I) hydroxide own strong alkaline, so its concentrated aqueous solution corrode glass. Thallous ion oxidize by chlorine, bromine, aqua regia and other oxidizing agent, which get thallium(III) hydroxide (Tl(OH)3). However Tl(OH)3 is not stable. On the counter, thallium III ion reduce by sulfur dioxide and hydrogen sulfide, which get thallous ion. Thallium(I) sulfate , thallium(I) oxide or thallium metal is the raw material.
