    Abstract: A glass ceramic is composed of glass frit powder (1) and 1-10 wt.% - cordierite fine powder (2) with the average particle size of 0.01- 0.2 μm. The glass frit powder (1) contains 45-55 wt.% SiO2, 15- 25 wt.% Al2O3, 15-25 wt.% MgO, 0.4-0.5 wt.% CaO, 0.9-1.5 wt.% B2O3 and 1.4-1.5 wt.% P2O3. A weight ratio of coarse glass frit powder to fine glass frit powder is 1:1.5-2.5. The above powder is molded by pressure molding method or doctor blade molding method, and it is heated to the temperature range of 800-1000 deg.C at a rate of 180-360 deg.C/hr, maintained for 20-120 min, and cooled at a rate of 120-240 deg.C/hr.

    Abstract translation: 玻璃陶瓷由玻璃粉末(1)和1-10重量%的平均粒度为0.01〜0.2μm的堇青石细粉末(2)组成。 玻璃料粉末(1)含有45-55重量%的SiO 2,15-25重量%的Al 2 O 3,15-25重量%的MgO,0.4-0.5重量%的CaO,0.9-1.5重量%的B 2 O 3和1.4〜 1.5重量%的P2O3。 粗玻璃料粉末与细玻璃料粉末的重量比为1:1.5-2.5。 上述粉末通过加压成型法或刮刀成型法成型,以180〜360℃/ hr的速度加热到800〜1000℃的温度范围,保持20〜120分钟, 并以120-240℃/ hr的速率冷却。
