Tellurium dioxide Metal

Characteristics: As a kind of amphoteric compound, tellurium dioxide is basically insolvable in water or ammonia, yet solvable in strong acid and alkali. This white solid tellurium dioxide powder will become yellowish after heating and turn dark yellowish red after fusing. its unique characteristics tellurium dioxide is an integral part of acousto-optic products as well as having good diffraction efficiency and it works very well at most power levels.

Application: Tellurium dioxide could be used in different fields, according to its purity and form
-Glass former for tellurite glasses frits
-Tellurium dioxide single crystal for optical devices
-Front-side silver pastes for solar cells
-Rubber vulcanizing accelerator
-Additive for electrical plating chemical
Tellurium dioxide is sometimes used to color ceramics. It has increasingly been used in optical refraction applications such as fiber optics and complimentary products. .It is even capable of being used for high speed or high resolution devices that need to handle high laser powers.
