Nano Violet Tungsten Oxide Powder Applied for Heat Insulation Coating

Nano violet tungsten oxide powder may be applied for producing heat insulation coating, and thus be used to prepare thin heat-insulating film for buildings and cars. Nano grain size violet tungsten oxide can also be used in violet tungsten oxide spray drying-direct carbonization to prepare nano particle size WC-Co composite powder, which is a new process based on spray drying-direct carbonization.

Why use violet tungsten oxide spray drying-direct carbonization method instead of spray drying-direct carbonization method to prepare nanometer WC-Co composite powder?nano violet tungsten oxide powder for preparing WC-Co composite powder picture
The spray drying-direct carbonization method for preparing WC-Co composite nanopowder has some disadvantages. For instance, the temperature range of reduction carbonization reaction is large, the phase is difficult to control accurately, and the carbon content in the powder is also difficult to control. While violet tungsten oxide spray drying-direct carbonization method is used to prepare WC-Co composite nano powder with the advantages of clear ideas, simple equipment, pure phase and precise control of carbon content.
