BZMT transparent ceramic, preparation method thereof and optical element
The invention relates to a BZMT transparent ceramic, a preparation method thereof and an optical element, and belongs to the technical field of transparent ceramic manufacturing. The preparation method comprises the following steps: mixing Ba (ZrxMgyTaz) O3 ceramic powder with a dispersing agent and water to obtain ceramic slurry; wherein x + y + z = 1, x > 0, y > 0, and z > 0; the solid content of the ceramic slurry is 70%-90%, and the Zeta potential is (-25 to-31) mV or (25 to 31) mV; when the shear rate is 10 (1/s), the viscosity of the ceramic slurry is 300-550mPa. S; injecting the ceramic slurry into a mold, standing and settling to obtain a plain blank; and sintering the blank at a certain temperature. The preparation method does not need to add an organic binder, does not need to discharge glue, also does not need to adopt complex processes such as dry pressing and cold isostatic pressing, and the prepared BZMT transparent ceramic has high transmittance and low scattering points, and can be effectively used for manufacturing optical elements.
本申请涉及一种BZMT透明陶瓷及其制备方法、光学元件，属于透明陶瓷制造技术领域。该制备方法包括如下步骤：将Ba(ZrxMgyTaz)O3陶瓷粉体与分散剂、水混合，得陶瓷浆料；其中，x+y+z＝1，x＞0、y＞0、z＞0；陶瓷浆料的固含量为70％～90％，Zeta电位为(‑25～‑31)mV或(25～31)mV；当剪切速率为10(1/s)时，陶瓷浆料的粘度为300～550mPa.s；将陶瓷浆料注入模具，静置沉降，获得素胚；将素胚在一定温度下烧结。该制备方法无需添加有机粘结剂、无需排胶，也无需采用干压、冷等静压等复杂工艺，制得的BZMT透明陶瓷具有高透过率和低散射点，可有效用于制作光学元件。
