Transparent ultraviolet-proof ceramic material and preparation method thereof
The invention discloses a transparent ultraviolet-proof ceramic material and a preparation method thereof. The preparation method comprises the following steps: treating a mixed material of yttrium oxide, zinc powder, lanthanum oxide and neodymium oxide in a manner of calcining for three times and ball-milling for three times to prepare a relatively homogeneous yttrium oxide-zinc oxide composite material; and placing a yttrium oxide and titanium dioxide mixed material on the surface layer of a ceramic material after annealing, during first-stage microwave sintering, fusing titanium dioxide again, and forming a thin film on the surface of the ceramic material through the fused titanium dioxide. Not only is the transmission of light of the ceramic material not affected, but also the ultraviolet-proof performance is enhanced, and yttrium oxide sinks into the ceramic material; The annealing treatment is carried out before the sintering, then the microwave sintering is carried out, first-stage microwave sintering is carried out under the pressurization condition, and second-stage vacuum microwave sintering is carried out; and the ceramic material taking the yttrium oxide-zinc oxide composite material as the main body has the ultraviolet-proof performance and also has the light transmission performance.
本发明公开了一种透明防紫外线的陶瓷材料及其制备方法，使用三次煅烧三次球磨的方式处理氧化钇、锌粉、氧化镧和氧化钕混料制得较为均质的氧化钇‑氧化锌复合材料；退火后置于陶瓷材料表层的氧化钇与二氧化钛混合材料，第一段微波烧结时，二氧化钛重新熔融，熔融二氧化钛在陶瓷材料表面形成薄膜，不仅不会对陶瓷材料透光性长生影响，还增强了防紫外线性能，而氧化钇下沉进入陶瓷材料；烧结前先进行一次退火处理，再进行微波烧结，在加压条件下进行第一段微波烧结，第二段为真空微波烧结；使这种以氧化钇‑氧化锌为复合材料为主体的陶瓷材料，在具备防紫外线的性能的同时，还具备透光性能。
