Preparation method of fluorescent transparent ceramic with high optical performance
The invention relates to a preparation method of fluorescent transparent ceramic with high optical performance. The preparation method comprises the following steps: (a) calcining metal oxide powder of yttrium oxide, aluminum oxide and cerium oxide; (b) putting the calcined metal oxide powder, calcium carbonate powder and tetraethoxysilane into a ball milling tank, adding a ball milling medium at the same time, and carrying out ball milling to obtain slurry; (c) drying the slurry, grinding and sieving the dried powder to obtain uniformly dispersed powder, calcining and cooling again, and sieving again to obtain final powder; (d) adding the final powder into a mold, carrying out dry pressing molding, and then carrying out cold isostatic pressing to obtain a biscuit; (e) sintering the biscuit; (f) annealing and processing the sintered biscuit to obtain the fluorescent transparent ceramic. Compared with ceramic obtained through one-step vacuum sintering, the fluorescent transparent ceramic is excellent in appearance, and the fluorescent transparent ceramic excellent in optical quality is obtained.
本申请涉及一种高光学性能的荧光透明陶瓷的制备方法，其包括以下步骤：(a)对氧化钇、氧化铝和氧化铈的金属氧化物粉体煅烧；(b)将煅烧后的金属氧化物粉体及碳酸钙粉、四乙氧基硅烷放入球磨罐中，同时加入球磨介质，进行球磨，得到浆料；(c)对浆料进行干燥处理，并将干燥后的粉体碾碎，过筛后，得到分散均匀的粉体，再次进行煅烧，冷却之后再次过筛，得到最终粉体；(d)将最终粉体加入模具内，干压成型之后，再冷等静压，得到素坯；(e)烧结素坯；(f)对烧结后的素坯进行退火、加工，得到荧光透明陶瓷。本申请比一步真空烧结的陶瓷外观优异，得到了一种光学质量优异的荧光透明陶瓷。
