Nano particle size violet tungsten oxide for ceramic microsphere may be used to produce tungsten powder. Researchers have observed the effect of violet tungsten oxide raw material on tungsten powder product. And they found that: The morphology of violet tungsten oxide under low-magnification SEM is characterized by uneven surface of the violet tungsten oxide aggregate with many fine micropores. The morphology of violet tungsten oxide in high-magnification SEM is characterized in that the aggregates are mainly composed of acicular or…
