High-temperature high-whiteness porcelain formed by secondary firing of fritted glaze and preparation method of high-temperature high-whiteness porcelain
The invention discloses a high-temperature and high-whiteness porcelain formed by secondary firing of fritted glaze and a preparation method of the high-temperature and high-whiteness porcelain, and belongs to the technical field of ceramic preparation and processing. The preparation raw materials of the daily high-temperature high-whiteness porcelain comprise a blank and fritted glaze, the blank material formula comprises the following components in percentage by weight: 20-40% of lithium china clay, 30-40% of lithium feldspar, 20-40% of kaolin and 5-10% of quartz; both the lithium china clay and the lithium feldspar are selected from Yichun 414 tantalum-niobium ore. Starting from the formula of the blank material, the lithium china clay and the lithium feldspar are selected, and the use amount is reasonably controlled, so that the defect of cracking of the glaze surface after secondary glaze firing of the fritted glaze on the blank material can be effectively improved. The daily high-temperature high-whiteness porcelain disclosed by the invention is simple in preparation process and low in preparation cost, has whiteness and transparency comparable to those of high-grade bone china, and has a very good market prospect.
本发明公开了一种上熔块釉二次烧成的高温高白瓷及其制备方法，属于陶瓷制备及加工技术领域。本发明日用高温高白瓷的制备原料包括坯料和熔块釉；所述坯料配方按重量百分比组成如下：锂瓷土20％‑40％、锂长石30％‑40％、高岭土20％‑40％、石英5％‑10％；所述锂瓷土、锂长石均选自宜春414钽铌矿。本发明从坯料配方入手，选用锂瓷土、锂长石并合理控制用量，能够有效改善坯料上熔块釉二次釉烧后釉面出现惊裂的缺陷。本发明日用高温高白瓷制备工艺简单，制备成本低，且白度、透度媲美高档骨质瓷，具有很好的市场前景。
