| ABSTRACT |
|
Effect of Li2O.4B2O frit on the microstructural and thermal expansion behaviour of $beta$-spodumene ceramics was investigated. With 4.0~8.0 wt.% frit addition, sintering temperature range was enlarged and densification was enhanced through liquid phase sintering. As the amount of frit addition was increased, thermal expansion coefficient was increased to 1.72$times$10-6$^{circ}C$-1 of its highest value, which indicated that the increment of thermal expansion coefficient due to the second phase was constrained. |
