Preparation method of magnesium aluminate spinel transparent ceramic with high light transmittance
The invention relates to a preparation method of magnesium aluminate spinel transparent ceramic with high light transmittance. The preparation method of the high-light-transmittance magnesium aluminate spinel transparent ceramic comprises the following steps: weighing an aluminum source and a Mg source as raw materials according to an aluminum-magnesium ratio, adding calcium fluoride as a sintering aid, mixing, forming to obtain a biscuit, and finally sintering to prepare the high-light-transmittance magnesium aluminate spinel transparent ceramic, the calcium fluoride is selected from at least one of calcium fluoride powder and calcium fluoride single crystal particles; the chemical formula of the magnesium aluminate spinel transparent ceramic is MgO.nAl2O3, wherein n is greater than or equal to 1 and less than or equal to 2.5.
本发明涉及一种高透光性镁铝尖晶石透明陶瓷的制备方法。所述高透光性镁铝尖晶石透明陶瓷的制备方法包括：采用铝源和Mg源作为原料，按照铝镁比称取原料，加入氟化钙作为烧结助剂并混合，再经成型得到素坯，最后经过烧结，制备高透光性镁铝尖晶石透明陶瓷；所述氟化钙选自氟化钙粉体和氟化钙单晶颗粒中至少一种；所述镁铝尖晶石透明陶瓷的化学式为MgO﹒nAl2O3，1≤n≤2.5。
