High purity silicon carbide (SiC) powder was synthesized in-situ by chemical reaction between silicon and carbon powder. In order to ensure that the impurity concentration of the resulting SiC powder is suitable for high-resistivity SiC single crystal growth, the preparation technology of SiC powder is different from that of SiC ceramic.
This paper studied the effects of powder size on densifiion, microstructure, and mechanical properties of the hot isostatic-pressed 2A12 aluminum alloy powder compact. The results show that the near-fully dense powder compact can be successfully achieved and the smaller the powder is, the higher the relative density is. In addition, as the powder size decreases, the precipitated phases in

The powder metallurgy is a method in which composites are formed by mixing the elements with different chemical properties in metal matrix. This technique provides a good chemical homogeneity to final product, huge potential saving in case of mass production, high production rate and excellent wear resistant properties of component produced.
For the interactions between SiC particles and suspension fluid the surface properties are also relevant for the final manufactured component properties in many forming processes. Due to a coating of the SiC particles the miscibility can be significantly improved, e.g. by adapting the hydrophobic or hydrophilic surface properties.
