摘要

测定莫来石反应热和生成的新方法。应用热传导原理，设计了一种反应热测量装置，研究了Al2O3与SiO2之间的反应速度。在750℃以上，由Al2O3和SiO2粉末混合形成莫来石，其活化能约为40 Kcal/mol。

熱分析による固相反應速度の研究 (第4報) アルミナとシリカの反應

New method of measuring the reaction heat and Formation of mullite.Applying the principle of the thermal conduction, the writer devised an apparatus of measuring the reaction heat by which the reaction velocity between Al2O3 and SiO2 is studied. Mullite is formed from the mixture of Al2O3 and SiO2 powder at above 750°C and this activation energy is about 40 Kcal/mol.
