摘要

以ZrB2和SiC粉末的混合物为原料。粉末在行星球磨机中研磨，与聚乙烯醇混合，筛分至0-125 μm。筛分后，粉末在Tekna Tek 15 ICP等离子装置中球化。在球化过程中，陶瓷粉末熔化并形成含有ZrB2-SiC的化合物，并迅速结晶形成致密的球形粉末，适用于增材制造或烧结技术。

Syntheisis of the ZrB2-SiC ultra-high temperature ceramic powder by plasma spheroidization

The mixture of ZrB2 and SiC powders were used as a raw material. The powders were milled in a planetary ball mill, blended with polyvinyl alcohol, and sieved to 0-125 μm. After sieving, the powder was spheroidized in Tekna Tek 15 ICP plasma plant. During the spheroidization, the ceramic powder melts and form a compound, containing ZrB2-SiC and rapidly crystallized forming dense spherical shaped powders, suitable for additive manufacturing or sintering techniques.
