Microwave Synthesis Method of Nano-tungsten Carbide Powder

The present invention provides a method of microwave synthesis of nano tungsten carbide. Steps are as follows:

1) Configuration in accordance with nano tungsten powder mixture and the mass ratio of phenolic resin by 3 to 1 configuration mix, then add alcohol, so that the mixture is completely soaked in alcohol and then mixing evenly, then heated in a water bath so that the alcohol evaporates fully obtain a phenolic resin and nano-tungsten powder mixture evenly mixed spare;

2) Configured to take a vacuum placed on the mixture of ceramic boat, and it was added powdered iron bars full contact, the vacuum is turned off oven, maintained at a vacuum degree 7-9Pa;

3) Start heating microwave oven carbonization , controlling the temperature of 850-1000 ℃, heating 5-10mi n After disconnecting the power, stop heating, and after cooling to room temperature, stop vacuuming, remove the powder carbonized to obtain nanometer WC powder The average particle size was 84.4nm.

Microwave Synthesis of Nano-tungsten carbide method of the present invention provides advantages: fast heating, carbonizing very short time, to get nanometer WC powder.
