High purity aluminum oxide crystal:

α -al2o3- 99.999%

aluminium oxide is of high purity, even particle distribution, high hardness and good resistance to high temperature.

application:

high purity aluminum oxide is mainly used in the growth of sapphire mono- and poly- crystal and yag laser crystal. Aluminum oxide can also be used in manufacturering translucent ceramics, fluorescent material and as advanced filler.

aluminum oxide polycrystal is of high density, and it can be used to grow sapphire monocrystalsingle crystal.

xinju's aluminum oxide powder is recognized as the best choice for yag crystal in china.


high purity aluminum oxide powde can be made into high purity sapphire polycrystal and excellent yag crystal. While the sapphire polycrystal can be made into sapphire monocrystal for led.

we can also provide you with 99.99% alumnium oxide for electical ceramics and 99.9% alumnium oxide for filler.

High purity tellurium dioxide powder (-teo2)

this white solid teo2 powder will become yellowish after heating and turn dark yellowish red after fusing. as a kind of amphoteric compound, tellurium dioxide is basically insolvable in water or ammonia, yet solvable in strong acid and alkali.

the monocrystal of tellurium dioxide can be used in infrared and acousto-optic devices, especially as infrared windows, and used in electrical components, while tellurium dioxide teo2 powder can be used as rubber vulcanizing accelerator and catalyst or addictive in electroplating and conductive silver paste industries.

teo2 powder can be used as rubber vulcanizing accelerator tdec, brightener for electroplating and electroless plating, glass former and tellurium glass powder for solar cells' front-side silver photovoltaic paste.

tellurium dioxide can also be used as contitional glass former, which means it will form a glass with small molar additional of a second compound such as an oxide or holide.

teo2 glasses have high refractive indices and transmite into the mid-infrared part of the eletromagnetic spectrum, therefore they are of technological interest for optical wavegnides.

tellurite glasses have also been shown to exhibit raman gain up to 30 times that of silica, useful in optical fiber amplication.
