The paper deals with a formation of artificial rock (clinker). Temperature plays the capital role in the manufacturing process. So, it is useful to analyze a poor clinker to identify the different phases and defects associated with their crystallization. X-ray fluorescence spectroscopy was used to determine the clinker's chemical composition. The amounts of the mineralogical phases are measured by quantitative XRD analysis (Rietveld). Scanning electron microscopy (SEM) was used to characterize the main phases of white Portland cement clinker and the defects associated with the formation of clinker mineral elements. The results of a study which focused on the identification of white clinker minerals and defects detected in these noncomplying clinkers such as fluctuation of the amount of the main phases (alite (C3S) and belite (C2S)), excess of the free lime, occurrence of C3S polymorphs, and occurrence of moderately-crystallized structures are presented in this paper.
本文论述了人造岩石（熟料）的形成。温度在制造过程中起着关键作用。因此，分析劣质熟料以识别与其结晶相关的不同相和缺陷是很有用的。采用X射线荧光光谱法测定熟料的化学成分。通过定量XRD分析（Rietveld法）测量矿物相的含量。利用扫描电子显微镜（SEM）对白色硅酸盐水泥熟料的主要相以及与熟料矿物元素形成相关的缺陷进行表征。本文介绍了一项研究结果，该研究重点是识别在这些不合格熟料中检测到的白色熟料矿物和缺陷，如主要相（阿利特（C3S）和贝利特（C2S））含量的波动、游离石灰过量、C3S多晶型物的出现以及中度结晶结构的出现。
