Composite ceramic powder and production process thereof. |
摘要 |
<p>This invention provides composite ceramic powder comprising matrix ceramic powder and fine particles of ceramic, metal or metal compound which are different from the matrix ceramic powder and dispersed in the matrix ceramic powder. The composite ceramic powder is produced by mixing matrix ceramic powder or its precursor with fine particles to be dispersed therein and then heating the resulting mixture. The composite ceramic powder is also produced by dispersing matrix ceramic particles or precursor thereof in an organic solvent with an organic compound as a dispersoid particle precursor and separating and recovering the organic solvent. The composite ceramic powder is suitable for producing sintered bodies having excellent properties, especially with respect to thermal conductivity, flexural strength and light transmittance, by a conventional ceramic fabrication process.</p> |
