Talc-clay-frit system talc domestic porcelain and preparation method thereof
The invention relates to the technical field of domestic ceramics, and particularly discloses talc-clay-frit system talc domestic porcelain and a preparation method thereof. Comprising the following preparation raw materials: calcined talc, clay and frit. The frit comprises lithium carbonate, aluminum oxide and quartz; the burnt talc comprises frit and raw talc. Theoretical research is carried out on the mechanism that the traditional talc porcelain is narrow in firing range, on the basis of the mechanism research, a new preparation process formula of a talc-clay-frit (small amount) system is proposed for the first time, a lithium frit is used as a flux, clay and decomposition products of the clay are dissolved by the lithium frit before SiO2-MS-M2A2S ternary eutectic reaction, and then the clay and the decomposition products of the clay are dissolved by the lithium frit before the SiO2-MS-M2A2S ternary eutectic reaction. Therefore, the ternary eutectic reaction is avoided, the total liquid phase quantity generated in the system is reduced, the sintering temperature range and the clay consumption of the talc porcelain are obviously improved, the forming performance of the talc porcelain is ensured, and the contradiction between the forming performance and the sintering performance in the production of the talc porcelain is fundamentally solved.
本发明涉及日用陶瓷技术领域，具体公开一种滑石‑粘土‑熔块体系滑石质日用瓷及其制备方法。包括如下的制备原料：烧滑石、粘土、熔块；所述熔块包括：碳酸锂、氧化铝、石英；所述烧滑石包括：熔块、生滑石。本发明针对传统滑石瓷烧成范围窄的机制行了理论研究，在机理研究基础上，首次提出滑石‑粘土‑熔块(少量)体系的新制备工艺配方，应用锂熔块作为熔剂，通过锂熔块在SiO2‑MS‑M2A2S三元低共熔反应之前先溶解粘土及其分解产物，从而避免三元低共熔反应，进而减少系统中产生的总液相量，显著提高滑石瓷的烧结温度范围和粘土用量，保证了其成形性能，从根本上解决了滑石瓷生产中成形性能与烧结性能的矛盾。
