Specification: |
The Tellurium, with the cas registry number 13494-80-9, is a kind of silvery white crystalline solid. Being soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, potassium hydroxide while insoluble in cold and hot water and carbon disulfide, this chemical could reacts with nitric acid and concentrated sulfuric acid with the form of red solution. Besides, it could dissolves in potassium hydroxide in the presence of air with formation of deep red solution. In addition, its product categories are including Inorganics; Electronic Chemicals; Micro/Nanoelectronics; Pure Elements; Metal and Ceramic Science; Metals; Tellurium.
The physical properties of this chemical are as below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 129.906223; (6)MonoIsotopic Mass: 129.906223; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.
The production method of this chemical is below: First prepare the raw material of Tellurium powder, and then extract and refine with sodium polysulfide to get this product with the purity of 99.999%.
As to its usage, it is widely applied in many ways. It could be used as a chemical bonder in producing the outer shell of the first atom bomb and also in the fileds of thermoelectricity and free-machining steel; It could then be used as the colorant for ceramics and glass, vulcanized agent of rubber, catalytic agent for petroleum cracking process.
When you are dealing with this chemical, you should be careful. For being a kind of toxic chemical, it will at low levels cause damage to health. If swallowed, it is also very toxic. Therefore, if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible).
In addition, you could obtain the molecular structure by using the following datas:
(1)Canonical SMILES: [Te]
(2)InChI: InChI=1S/Te
(3)InChIKey: PORWMNRCUJJQNO-UHFFFAOYSA-N
