Tellurium Dioxide Powder High Purity Metals TeO2 CAS 7466-07-3 For Front - Side Pastes
Tellurium dioxide (TeO2) is a solid oxide of tellurium.
It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2.
Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.

Application of Tellurium dioxide powder TeO2
1. Tellurium Dioxide is used in front-side pastes, acousto-optical devices, infrared sensor, tellurite glass,avionics fiber optic system architectures, electroplating industry, and as anti-corrosive agent material in electronic elements.
2. Sometimes used to color ceramics, tellurium dioxide has increasingly been used in optical refraction with the end use of glass fibers (fiber optics).
3. Tellurite glasses have also been shown to exhibit Raman gain up to 30 times that of silica, useful in optical fibre amplification.
4. Tellurium Dioxide is also used in Ag paste additive, chemical nickel-plating, acousto-optic device etc
Properties of Tellurium dioxide powder TeO2
TeO2 is barely soluble in water and soluble in strong acids and Alkai metal hydroxides.
It is an amphoteric substance and therefore can act both as an acid or as a base depending on the solution it is in.
It reacts with acids to make tellurium salts and bases to make tellurites.
It can be oxidized to telluric acid or tellurates.
1: May I get one sample before placing order?
Re: Yes, we'd like to provide sample for you. For those normal products, you just need to bear the freight; for those high value products, you just need to freight and a little product cost. When we both cooperate for some times or when you are our VIP customer, free sample will be offered when you need.
2: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, T/T, EMS, etc.) or by air. Usually it will cost 2-5 days that you can get the goods after delivery.
For large quantity products, It will cost days to weeks to come to your destination port, which depends on where the port is.
3: Is there any possible to use my appointed label or package?
Re: Sure. we'd like to use label or package according to your requirement if needed.
4: How can you guarantee the goods you offer is qualified?
