Ceramic material sintering shrinkage adjusting method
The invention discloses a method for adjusting the sintering shrinkage rate of a ceramic material, and relates to the field of manufacturing of high-temperature co-fired ceramic materials. Raw materials comprise plate-shaped aluminum oxide, granular aluminum oxide and a sintering aid, wherein the aluminum oxide accounts for 95% (the sum of the plate-shaped aluminum oxide and the granular aluminumoxide) and the sintering aid accounts for 5%. The shrinkage adjusting method comprises the following steps: a) setting an initial proportion of plate-shaped/granular aluminum oxide; b) uniformly mixing the components in the raw materials; c) adding an organic additive, drying and molding the components; d) sintering the mixture at 1500-1600 DEG C to form ceramic, and e) correspondingly adjusting the ratio of plate-shaped/granular alumina according to the initial shrinkage rate. In the invention, the green body density and sintering shrinkage rate of the ceramic material are effectively adjusted by compounding the plate-shaped alumina and the granular alumina.
本发明公开了一种陶瓷材料烧结收缩率调整方法,涉及高温共烧陶瓷材料制作领域。所用原材料包括:板状氧化铝、粒状氧化铝、烧结助剂,其中氧化铝占比95%(板状氧化铝与粒状氧化铝之和)、烧结助剂占比5%。收缩率调整方法包括以下步骤:a)设定板状/粒状氧化铝的初始比例;b)将原料中各组分混合均匀;c)加入有机添加剂干燥成型;d)于1500℃~1600℃下烧结成瓷;e)根据初始收缩率相应地调整板状/粒状氧化铝的配比。本发明通过板状氧化铝与粒状氧化铝相复合的方式,有效地调整了陶瓷材料的生坯密度以及烧结收缩率。
