LAS계 내열충격성 재료의 미세구조 제어 (I): $Li_O$.$4B_2O_3$ 프릿트 첨가가 $\beta$-Eucryptite 세라믹스의 미세구조 및 열팽창특성에 미치는 영향 = A Study on the Microstructural Control of LAS Ceramics (I): $Li_O$.$4B_2O_3$ Frit Addition on the Microstructure and Thermal Expansion of $\beta$-Eucryptite Ceramics

다국어 초록 (Multilingual Abstract)

Influence of Li2O.4B2O3 frit addition on the microstructure and thermal expansion properties of $\beta$-eucryptite ceramics was studied. With 1.0~10.0wt% frit addition, sintering temperature range was enlarged and densified body was obtained. Thermal expansion was increased from -6.67$\times$10-6 $^{\circ}C$-1 of pure sintered body to 1.03$\times$10-6$^{\circ}C$-1 of 6 wt% added body, but this increasement was accompanied by inhibition of thermal expansion anisotropy, so that improved microcracking property.
