Lamellar highly textured ceramic and preparation method thereof
The invention relates to a preparation method of lamellar highly textured ceramic, which comprises the following steps of mixing lamellar ceramic powder with a solvent according to the mass-volume ratio of 20-40 g/L, and carrying out high-speed shearing at the speed of 10<4>-4*10<4> r/min to obtain an ultrafine powder dispersion liquid, drying the ultrafine powder dispersion liquid in sequence toobtain nano-micron powder, and pouring the dried powder into a mold, carrying out heat treatment at 300-800 DEG C, carrying out heat preservation for 5-10 minutes, and demolding to obtain the lamellarhighly textured ceramic. According to the lamellar highly textured ceramic and the preparation method thereof provided by the technical scheme, the problems of high energy consumption, long sinteringtime and large equipment input in the existing processing method can be effectively solved.
本发明涉及一种层状高度织构陶瓷的制备方法，包括以下步骤：将层状陶瓷粉体与溶剂按照20～40g/L的质量体积比混合，之后在104～4×104转/分的速度下进行高速剪切工序，即得超细粉体分散液；将超细粉体分散液依次经过干燥工序后得到纳微米粉体；将干燥粉体倒入模具中，于300～800℃温度下进行热处理，保温5～10min后进行脱模，即得层状高度织构陶瓷。上述技术方案中提供的层状高度织构陶瓷及其制备方法，其能有效解决现有加工方法存在的所需能耗较高、烧结时间较长以及设备投入量较大的问题。
