During sand casting, the binders produces gases in cores because high temperature molten metals dissolve the binders into gases and causes gas defects in the casting products. In the present study, quantitative analysis of inorganic binder gas generation was performed using Thermo Gravimetry (TG) and Mass Spectrometer (MS) analyses. The specimen was prepared using organic binders in liquid and solid state, and a mixture of sand and binders. Moisture loss by catalysts was calculated by TG results from liquid and solid binder specimens; it was found that components of gases were different. Quantitative analysis was discussed for generated gases with individual gas component results obtained using TG and MS. It is expected that gas generation can be predicted in the casting simulation using the technique proposed in the present study.
