There is further described a crystalline catalyst comprising the elements nickel, magnesium, aluminium and a lanthanide element, in which the crystalline phase is a spinel phase.
还描述了包括元素镍、镁、铝和镧系元素的结晶催化剂，其中结晶相为尖晶石相。
When the reaction products form as high melting point CA2, CA6 and MA spinel in a continuous solid phase it will clog the liquid channel and resist the further diffusion of fused slag in the brick.
并且当熔渣与耐火材料的反应产物为高熔点的CA2、CA6和MA尖晶石相且连续交错分布时，能堵塞液相扩散通道，抑制熔渣向耐火材料内部的进一步渗透。
The changes in chemical and phase composition of spinel in the grain and matrix of specimens after high temperature treatment have also been investigated.
分析了试样经高温处理后基质和颗粒中的尖晶石相组成及化学成分的变化规律。
