Burnt talc-clay system talc domestic porcelain and preparation method thereof
The invention relates to the technical field of domestic ceramics, and particularly discloses fired talc-clay system talc domestic porcelain and a preparation method thereof. Comprising the following preparation raw materials: calcined talc and clay. The calcined talc comprises the following preparation raw materials: potassium carbonate and raw talc. Theoretical research is carried out aiming at the mechanism that the traditional talc porcelain is narrow in firing range, on the basis of the mechanism research, a talc-clay firing system is proposed for the first time, potassium carbonate is used as a flux, the flux is added in advance when talc is calcined, clay and decomposition products thereof are dissolved before SiO2-MS-M2A2S ternary eutectic reaction, the total liquid phase amount generated in the system is reduced, and the total liquid phase amount generated in the system is reduced; the preparation method has the advantages that the sintering temperature range and the clay dosage of the talc porcelain are obviously increased, the forming performance is guaranteed, compared with a certain factory, the light transmittance is increased by 21.5%, the whiteness is increased by 10.9%, the breaking strength is increased by 10%, the contradiction between the forming performance and the sintering performance in talc porcelain production is fundamentally solved, and the green development of the talc porcelain is facilitated.
本发明涉及日用陶瓷技术领域，具体公开一种烧滑石‑粘土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；所述烧滑石包括如下的制备原料：碳酸钾、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，首次提出烧滑石‑粘土体系，将碳酸钾作为熔剂，熔剂在煅烧滑石时提前加入，在SiO2‑MS‑M2A2S三元低共熔反应之前先溶解粘土及其分解产物，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，保证成形性能，相比某厂滑石质日用瓷透光度提升21.5％，白度提升10.9％，抗折强度提升10％，从根本上解决滑石瓷生产中成形性能与烧结性能的矛盾，有利于滑石质日用瓷的绿色发展。
