Formula and process of opaque porcelain
The invention relates to a formula and a process of opaque porcelain. The adopted technical scheme is as follows: the transparency of the porcelain powder is controlled by changing the content of chemical substances in the porcelain powder, all the components are weighed, uniformly mixed and then sintered at high temperature in a crucible for use, a certain amount of zirconium-tin-titanium opacifier and nucleating agent are introduced into a frit, and the frit is opacified or devitrified by recrystallization or phase division action, so that the opaque porcelain is formed. The preparation method has the beneficial effects that the zirconium opaque glaze, the tin opaque glaze and the titanium opaque glaze are added, two or three of the zirconium opaque glaze, the tin opaque glaze and the titanium opaque glaze can be combined to form a mixed opaque state according to different opaque forms, the three combined effects are adopted in the process formula, the nucleating agent calcium fluoride is introduced, and the opaque is formed through original crystal grain suspension; and when the thickness of the porcelain powder is 0.2 mm, the color requirement can be met, and the aesthetic form of teeth can be reproduced.
本发明涉及一种不透明体瓷的配方及工艺。采用的技术方案是：通过改变瓷粉里化学物质的含量来控制瓷粉的透明度，称量各组分混合均匀后在坩埚里高温烧结后使用，在熔块中引入一定量的锆锡钛乳浊剂和成核剂，重结晶或分相等作用而使其乳浊或失透，从而形成不透明体瓷。本发明的有益效果：通过加入锆乳浊釉，锡乳浊釉和钛乳浊釉，根据乳浊的形态不同还可以两者或三者结合形成混合乳浊状态，本工艺配方采用三种联合作用，并引入成核剂氟化钙，通过原始晶粒悬浮形成乳浊，使瓷粉的厚度在0.2mm时就能满足色彩需求，并能再现牙齿的美学形态。
