Tlhaloso ea Sehlahisoa

E na le ponahalo ea tšepe e tšoeu ea silevera, boima ba 6.25 g / cm3, sebaka se qhibilihisang sa 452 ° C, ntlha e belang ea 1390 ° C, le boima ba 2.5 (Mohs hardness). Ho na le mefuta e 'meli ea allotropic, crystalline le amorphous. Tellurium e chesa moeeng ka lelakabe le leputsoa 'me e hlahisa tellurium dioxide; e ka arabela ka li-halogens empa eseng ka sebabole le selenium. E qhibiliha ka sulfuric acid, nitric acid, potassium hydroxide le potassium cyanide solution. Phetiso e mpe ea mocheso le conductivity ea motlakase. Tellurium e nang le bohloeki bo fetang 99.99% e bitsoa high-purity tellurium.
