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

Abstract

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.
