| titleOfInvention | Method for manufacturing mullite ceramic substrate |
| abstract | (57) [Summary] [Objective] A mullite-based ceramic substrate is obtained by low-temperature baking at 800 to 1200 ° C without performing calcination. [Structure] Alumina sol prepared by hydrolysis of aluminum alkoxide is converted to Al 2 O 3 in an amount of 50 to 70. 20% by weight in terms of SiO 2 of silica sol prepared by hydrolysis of silicon alkoxide and having silica particles in the dispersed phase coated with boehmite, and B 2 by firing. The first compound capable of generating O 3 is 1 to 15% by weight in terms of B 2 O 3 , and the second compound capable of generating CaO by firing is Ca. A ceramic slurry containing 1 to 20 wt% in terms of O and 1 to 7 wt% in terms of MgO of a third compound capable of forming MgO by firing is prepared. The ceramic slurry is dried to form a green sheet, and the green sheet is fired at a temperature of 800 to 1200 ° C. to obtain a mullite ceramic substrate. |
