摘　　要：就硅铝钙、硅铝钡合金中硅量的测定进行了试样的混合熔剂熔融试验,发现在石墨（粉）坩埚中熔融试样,硅鉬蓝分光光度法测定硅铝钙、硅铝钡合金中硅含量,可测定硅的含量范围为10%～25%,能够满足日常分析要求。The sample is melted to determinate silicon content in Si-Al-Ba and Si , Al , Ca. Melting sample can be found in the graphite crucible. Spectrophotometry with silicon molybdenum-blue has been applied to determine silicon content in Si-Ca and Si-Al-Ba alloy, the measuring range is 10%～25%, which can meet daily request for analysis.
