In this case, the solidification of the liquid phase formed at the hipping temperature led to the formation of crystalline intergranular phases at all temperatures: however, the chemical compositions of the intergranular phases formed in the specimens with and without carbon additions were different, since for high carbon contents the resulting intergranular phase was observed to be richer in Yttrium(85% at Y/15% at Si).

在这种情况下，加压温度下液态产物的凝固在所有温度范围下都将生成间粒晶体：但是，是否添加了碳则将会使产物晶体的化学成分发生不同，因为在高碳含量下，产物晶体会更富含钇(85%Y比15%Si)另一方面，我们必须强调的时，如果Al2O3作为第三方物质加入反应混合物粉末中，那么产物晶体的结晶度将被破坏。
