<= d - d> Chemical properties

Tellurium dioxide melts to form a red liquid.
Because of its amphoteric nature, tellurium dioxide is soluble in acid and alkali, slightly soluble in water, and has the smallest solubility at =. Can be oxidized to telluric acid or tellurate by strong oxidants.
<= d - d> Product usage
Tellurium dioxide is used in acousto-optical devices. Because it has birefringence and optical rotation characteristics, the optical rotation is / and the speed of sound propagating along the direction is only /, so it is a high-quality acousto-optic material. Tellurium dioxide is used to make glass with special properties. Tellurium glass has a high refractive index and can penetrate electromagnetic waves in the mid-infrared band.
Tellurium dioxide can also be used as a brightener in electroplating solutions, a catalyst for petroleum cracking, and a colorant for ceramics and glass. It is added to steel to increase ductility.
Tellurium dioxide is added to lead to increase strength and corrosion resistance. It is also a vulcanizing agent for rubber. It is also a material for manufacturing photoresistors and photovoltaics
