AB - Two types of CaO-Al2O3-SiO2 (CAS) glass powder applied spray coating on the surface of sintered Al2O3 were researched for sintering behavior; (1) Si-rich, glass containing high content SiO2, (2) Ca-rich, containing high content CaO. Foaming of bubbles remaining inside the Ca-rich glass was produced at a viscosity of approximately 107~109 poise,resulting in decreasing shrinkage (interfering with sintering) and increasing surface roughness. In case of Si-rich glass, there was no serious foaming bubbles phenomenon like Ca-rich below 1000°C, however cristobalite crystals with low density occurred at 1200°C and then produced re-foaming of bubbles, resulting in abnormal sintering behavior. These phenomenon is considered to be a decrease in viscosity due to an increase in the Ca content of the glass according to the formation of low-density cristobalite crystals. Therefore, in case of CAS glass, it is necessary to consider the increase of surface roughness and the sintering interference because of foaming bubbles phenomenon at low temperature sintering. Especially,when containing high SiO2 content, abnormal foaming phenomenon due to crystallization at high temperature should be predicted.
