| Abstract: | CoWO4-WO3 composite nanometer powders used for WC-Co hard alloy were prepared by using incorprecipitate method.The composite powder obtained is amorphous and the particle size is below 10 urn. The effects of synthetic condition on the properties of composite powders and the reaction mechanism were studied in detail by using TG-DTA, XRD and TEM techniques. |
