本文研究了粗晶锆酸钙作为钛熔体坩埚材料的腐蚀性。用扫描电镜结合能谱分析和电子背散射衍射（EBSD）对腐蚀过程进行了研究.因此，EBSD提供了检测钛与锆酸钙接触形成的相的可能性。结果表明，耐火材料的溶解主要受锆和氧向钛熔体的扩散控制。
This contribution examines the corrosion of coarse grain calcium zirconate as a crucible material for titanium melts. The corrosion was investigated by SEM in combination with EDX and electron back scatter diffractin (EBSD). Thereby the EBSD offered the possibility of detecting the phases formed of titanium in contact with calcium zirconate. It was found that the dissolution of the refractory material was mainly controlled by the diffusion of zirconium and oxygen towards the titanium melt.
