化学成分分析
chemical compsition analysis
化学湿法分析和仪器分析。化学湿法分析(以化学反应为签础的分析方法)包括重量分析和容量分析;仪器分析包括光学分析及电化学分析等。用于耐火材料的仪器分析主要有荧光X射线光谱分析、原子吸收光潜分析(见彩图擂页第12页)火焰光度分析、比色分析等。 化学成分分析结果是判断耐火材料的化学成分是否达到耐火材料标准所规定的要求，也是生产工艺中配方的主要依据。 中国已有6。个供耐火材料化学成分分析用的国家标准和行业标准。 (郑祥华)huaXUe Chengfen fenX}化学成分分析(chemical comPositionanalysis)应用化学和物理学原理，确定材料化学成分组成的方法。分为定性分析(鉴定含有的成分)和定量分析(确定该成分的含量)。化学成分分析包括
