Low-temperature sintered ceramic material and preparation method thereof
The invention discloses a low-temperature sintered ceramic material and a preparation method thereof. The low-temperature sintered ceramic material is prepared from the following components in percentage by mass: 10.0 to 15.5 percent of MgO, 31.0 to 35.5 percent of Al2O3, 44.5 to 50.5 percent of SiO2, 1.0 to 7.0 percent of B2O3 and 2.0 to 5.0 percent of Li2O. According to the preparation method, main components including a part of MgO, b parts of Al2O3 and c parts of SiO2 and additives including d parts of B2O3 and e parts of Li2CO3 are co-fired at low temperature to obtain the ceramic material, a is 13.1%-14.5%, b is 33.2%-36.7%, c is 48.8%-53.7%, a + b + c is 100.0%, d is 2.0%-7.0%, e is 9.0%-12.0%, and d and e are the percentages of the corresponding additive content relative to the main component content of the ceramic material respectively. According to the prepared low-temperature sintered ceramic material, the sintering temperature of a ceramic material of an Mg-Al-Si system can be reduced to 900 DEG C or below, and therefore co-firing matching with silver paste is achieved.
本发明公开了一种低温烧结陶瓷材料及其制备方法，其中低温烧结陶瓷材料包括以质量分数计10.0～15.5％的MgO、31.0～35.5％的Al2O3、44.5～50.5％的SiO2、1.0～7.0％的B2O3和2.0～5.0％的Li2O。其制备方法，以质量分数计使用主成分a份MgO、b份Al2O3、c份SiO2以及添加剂d份B2O3和e份Li2CO3低温共烧得到所述陶瓷材料，其中，a为13.1～14.5％，b为33.2～36.7％，c为48.8～53.7％，a+b+c＝100.0％，d为2.0～7.0％，e为9.0～12.0％，d、e分别为对应添加剂含量相对于陶瓷材料主成分含量的百分比。本发明制得的低温烧结陶瓷材料能够实现将Mg‑Al‑Si体系的陶瓷材料烧结温度降低至900℃以下，从而实现和银浆共烧匹配。
