A feature of silicate materials is that they can exist in two antagonistic states-amorphous and crystalline. In both cases, alkalis, which are always present in chemical compositions, play an important role. A feature of alkalis in the composition of silicate materials is that at certain stages of the synthesis of products, they play a positive role, reducing the temperature of synthesis, but worsening the properties of these products at the stage of their operation. Synthesis products should be understood as important building materials such as building glass and cement. It is known that the performance properties of glass and cement can be improved by the extraction of alkalis. In the first part of the article, the issues of extraction of alkalis in amorphous silicate materials-inorganic glasses were considered. This article presents the results of studies on the extraction process of alkalis in crystalline silicate materials-cement.
硅酸盐材料的一个特点是它们可以以两种相互对立的状态存在——非晶态和晶态。在这两种情况下，化学成分中总是存在的碱起着重要作用。硅酸盐材料成分中碱的一个特点是，在产品合成的某些阶段，它们发挥着积极作用，降低了合成温度，但在产品使用阶段却会使这些产品的性能变差。合成产品应理解为重要的建筑材料，如建筑玻璃和水泥。众所周知，通过去除碱可以提高玻璃和水泥的性能。在文章的第一部分，探讨了非晶态硅酸盐材料——无机玻璃中碱的去除问题。本文介绍了关于晶态硅酸盐材料——水泥中碱的提取过程的研究结果。
