Sodium-calcium-silicon transparent ceramic and preparation method thereof
The invention provides a sodium-calcium-silicon transparent ceramic and a preparation method thereof. The sodium-calcium-silicon transparent ceramic comprises the following components by mole percent: 45-50% of SiO2; 30 to 35 percent of CaO; 15 to 18 percent of Na2O; 1 to 6 percent of ZrO2; and 0 to 6 percent of B2O3. The preparation method comprises the following steps: melting the raw materials at the temperature of not lower than 1500 DEG C, clarifying and homogenizing, cooling and forming, and annealing in the temperature range of 550-650 DEG C to obtain the transparent glass. And carrying out heat treatment on the annealed glass to obtain the transparent ceramic. Compared with a traditional transparent ceramic preparation technology, the preparation method is mild in preparation condition, simple in process and low in equipment requirement, and large-size preparation can be achieved.
本发明提供一种钠钙硅透明陶瓷及其制备方法。所述钠钙硅透明陶瓷按照摩尔百分比包括如下组分：SiO2:45‑50％；CaO:30‑35％；Na2O:15‑18％；ZrO2:1‑6％；B2O3:0‑6％。所述制备方法为将所述组成的原料在不低于1500℃的温度条件下熔融，澄清均化后冷却成形，并在550‑650℃温度范围内退火得到透明玻璃；将退火后的玻璃进行热处理，得到透明陶瓷。与传统的透明陶瓷制备技术相比，本发明制备条件温和，工艺简单，对设备要求低，且可实现大尺寸制备。
