在简化的实验条件下，通常采用纯熟料相来测试水泥水化行为。这些相在结构上大体相同，但在化学上却比在技术熟料中发现的被大量取代的相简单得多。本文介绍了纯相的合成，首先描述了硅酸盐水泥中四种主要相的相关系和可能的多晶型，即硅酸三钙、硅酸二钙、铝酸三钙和铝铁氧体四钙。详细描述了固态合成的过程，包括对设备和技术的实用建议。此外，还给出了已成功使用的混合组合物。
Pure clinker phases are often used to test cement hydration behavior in simplified experimental conditions. These phases are in general structurally identical to, but chemically much simpler than their heavily substituted counterparts found in technical clinkers. The synthesis of the pure phases is covered in this paper, starting with a description of phase relations and possible polymorphs of the four main phases in Portland cement, i.e. tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium alumino ferrite. Details of the process of solid state synthesis are described including practical advice on equipment and techniques. In addition, mix compositions that have been successfully used are given.
