Specification
The Tellurium oxide, with CAS registry number 13451-18-8, has the systematic name of oxotellane dioxide. This chemical is an inorganic chemical compound of tellurium and oxygen. And the Tellurium oxide has two forms: α-TeO3 and β-TeO3. The α-TeO3 is yellow-red and the other one is grey, rhombohedral. What's more, its EINECS is 231-193-1.
Physical properties of Tellurium oxide: (1)#H bond acceptors: 3; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 51.21 Å2.
There are two differents ways of preparation about the two forms: α-TeO3 and β-TeO3. The α-TeO3 can be prepared by heating orthotelluric acid, Te(OH)6 at over 300°C . The β-TeO3 form can be prepared by heating α-TeO3 in a sealed tube with O2 and H2SO4.
