<P>PROBLEM TO BE SOLVED: To provide a setter for the heat-treatment of a glass substrate, which is a setter for the heat-treatment of the glass substrate which has a high strain point and contains 5-30% Na<SB>2</SB>O and K<SB>2</SB>O in total, provided that the setter hardly warps, even when repeatedly used in the temperature range for the heat-treatment of the glass substrate. <P>SOLUTION: As the setter for the heat-treatment of the glass substrate, a Li<SB>2</SB>O-Al<SB>2</SB>O<SB>3</SB>-SiO<SB>2</SB>based ceramic sintered compact is used, wherein the sintered compact has a porosity of 10-60% and contains at least 0.01% of (Fe<SB>2</SB>O<SB>3</SB>+MgO+CaO+ZnO+TiO<SB>2</SB>) and has petalite, β-eucryptite or β-spodumene as a crystal layer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
