High-strength cordierite porcelain and manufacturing method thereof
The invention provides a high-strength cordierite porcelain, and relates to the technical field of ceramics. The cordierite porcelain comprises a blank material and a glaze material; the blank material of the cordierite ceramic comprises the following components: 20-40% of Guangfeng black talc, 15-35% of calcined white talc, 5-12% of aluminum powder, 15-25% of kaolin, 11-15% of feldspar, 4-7% of zirconium silicate and 2-4% of lithium chinastone; and the glaze of the cordierite porcelain comprises the following components: 5-8% of kaolin, 35-45% of feldspar, 15-20% of quartz, 5-10% of calcined talc, 10-20% of frit and 5-8% of ZnO. The high-strength cordierite porcelain disclosed by the invention not only has mild and transparent quality of high-grade bone china, but also has high strength, high transparency and quenching resistance of reinforced porcelain. The performance indexes are as follows: the breaking strength is greater than or equal to 200MPa, the whiteness is greater than or equal to 81%, the light transmittance is greater than or equal to 80%, the water absorption is less than or equal to 0.1%, and the heat stability is that cracking is avoided after three times of heat exchange at 20-220 DEG C.
本发明提供了一种高强度堇青石瓷，涉及陶瓷技术领域，所述堇青石瓷包括坯料和釉料；堇青石瓷的坯料组分为广丰黑滑石20‑40％，煅烧白滑石15‑35％，铝粉5‑12％、高岭土15‑25％，长石11‑15％、硅酸锆4‑7％、锂瓷石2‑4％；堇青石瓷的釉料组分为高岭土5‑8％，长石35‑45％，石英15‑20％，烧滑石5‑10％，熔块10‑20％，ZnO 5‑8％。本发明的一种高强度堇青石瓷既有高档骨质瓷的温润透明品质，又有强化瓷的高强度、高透度、耐急冷性能。其性能指标：抗折强度≧200MPa,白度≧81％，透光度≧80％，吸水率≦0.1％。热稳定性在20‑220℃之间热交换三次不裂。
