摘　　要：CaO-B2O3-SiO2玻璃陶瓷中各晶相的组成及含量对其性能有重要影响。为定量分析玻璃陶瓷中的晶相含量,利用全谱拟合法分析玻璃陶瓷中β-CaSiO3、SiO2、CaB2O4晶相的相对质量比;利用分峰法计算出玻璃陶瓷的结晶度,从而得到玻璃陶瓷中各晶相的含量。与内标法计算结果比较,该方法得到的结晶度偏差为1.21%,晶相绝对含量的最大偏差为3.52%。该方法不需要内标,简便易行,可用于定量分析含有晶相和玻璃相的复合材料,为其实验提供理论分析的依据。Crystal compositions and contents have significant impact on the performance of the CaO-B2O3-SiO2 glass-ceramics. In this paper, a new method by combining full spectrum fitting method and peak separation method to quantitatively analyze the content of the crystalline phase in the glass ceramics was proposed. Quantitative analysis of CaO-B2O3-SiO2 glass-ceramics by full spectrum fitting method could calculate the relative content of β-CaSiO3 ,SiO2 ,CaB2O4 crystal phases. The crystallinity was calculated by using peak separation technology. Accordingly, the crystal phase content of CaO-B2O3-SiO2 glass-ceramic could be obtained. Comparing this method with the internal standard method, it was found that the maximum deviation of the crystallinity and the absolute weight fraction of crystalline phase were 1.21% and 3.52%, respectively. Therefore, this method was simple and did not require internal standard. This method can be applied to quantitatively analyze the phase of composite materials that contain crystalline and glass phases, and provides theory basis for the experimental study of glass-ceramics.
