Abstract: In order to develop dense Sr-hexacelsian and Sr-celsian ceramics, amorphous materials (nSrO-Al[2]O[3]-2SiO[2],n = 1.0 -1.2) prepared by calcining the mixtures of elutriated pure kaolin with strontium carbonate were pressed and heat-treated between 900 and 1200℃. Heat-treatment of the reactive amorphous powders above 950℃ produced densely sintered hexacelsian ceramics and phase transition of hexacelsian to celsian was observed at higher heat-treatrnent temperatures. With the increase in n value,transition temperature lowered from 1100 to 1000℃. When the stoichiometric specimens( n = 1.0) were heat-treated above 1150℃, cracks appeared at the surface of specimens owing to the phase transition of hexacelsian to celsian. Increase in n value above 1.1 depressed the crack formation and gave a crack-free polycrystals.
