Thallium bromide-iodide crystals have been used as infrared optical materials.
Thallium along with sulfur or selenium and arsenic is used to produce low melting glasses witch become fluid between 125 and 150C. These glasses have properties at room temperatures similar to ordinary glasses and are said to be durable and insoluble in water.
