Abstract Quartz ceramics have excellent properties such as low thermal conductivity, low expansion coefficient, high temperature resistance and thermal stability, but low toughness. The quenching method of quartz ceramic is as follows: (1) A hard phase is formed in the quartz ceramic. (2) Improve the surface coating. (3) Short fiber reinforcement. (4) The graphite particles are dispersed and quenched. (5) Have silicone resin reinforcer. (6) Improve mineralizers. In order to improve the toughness of quartz ceramics, a hardening mineralizer is selected in this experiment. In this experiment, quartz is used as the main raw material, and a mineralizer is selected as the aluminate, feldspar and Al2O3 powder cement. Quartz ceramics are prepared by molding. Adding 10% Al2O3 powder, adding Al2O3 powder can improve the flexural strength of quartz ceramics, and the flexural strength of quartz ceramics can reach 10 MPa. SEM analysis shows that the addition of Al2O3 can inhibit the grain boundary motion speed better and prevent grain growth, enhancement and enhancement. XRD analysis shows that the addition of aluminate cement, feldspar and calcium oxide may be beneficial to the conversion of quartz to cristobalite and the addition of Al2O3 to the conversion of quartz to phosphorus quartz.

矿化剂增韧石英陶瓷的制备研究

摘要 石英陶瓷具有导热系数低、膨胀系数低、耐高温、热稳定性好等优良性能，但韧性低。石英陶瓷的淬火方法如下： (1)在石英陶瓷中形成硬质相。(2)改进表面涂层。(3)短纤维增强。(4)石墨颗粒分散并淬火。(5)有硅树脂增强剂。(6)改进矿化剂。为提高石英陶瓷的韧性，本实验选用硬化矿化剂。本实验以石英为主要原料，选矿剂为铝酸盐、长石和Al2O3粉水泥。石英陶瓷是通过模压制备的。添加10%的Al2O3粉，添加Al2O3粉可提高石英陶瓷的抗弯强度，石英陶瓷的抗弯强度可达10MPa。SEM分析表明，Al2O3的加入可以更好地抑制晶界运动速度，阻止晶粒长大、强化和强化。XRD分析表明，铝酸盐胶结物、长石和氧化钙的加入可能有利于石英向方石英的转化，以及Al2O3的加入有利于石英向磷石英的转化。
