Preparation method of high strength high aluminum ceramic thin plate
The invention relates to a preparation method of a high strength high aluminum ceramic thin plate. The preparation method comprises following steps: (1) processing raw materials: ball-milling coal based kaolin, calcined bauxite, common kaolin, potash feldspar, soda feldspar, and talcum in a ball-milling machine, sieving, and saving the powder for later use; (2) proportioning and mixing raw materials: weighing raw materials according to percentages by weight, adding a blank enhancer, and mixing to obtain a mixture; (3) carrying out granulation and aging; (4) carrying out semi-dry pressing and moulding; (5) drying; (6) glazing; and (7) sintering: placing a dried blank in a roller kiln, and sintering to obtain the high strength high aluminum ceramic thin plate. Calcined bauxite is used to replace industrial alumina to introduce Al2O3 into the system; densely grown short rod like mullite of coal based kaolin is used to enhance the strength of the thin plate; the impurity namely TiO2 of calcined bauxite and added TiO2 are used to reduce the sintering temperature; the prepared thin plate has the characteristics of high strength and low sintering temperature, and the cost is reduced.
本发明涉及一种高强高铝质陶瓷薄板的制备方法，其步骤如下：1)原料处理：将煤系高岭土、煅烧铝矾土、普通高岭土、钾长石、钠长石和滑石分别用球磨机球磨，过筛备用；2)原料配比与混合：各原料质量百分数称取原料并加入坯体增强剂后混合，得到混合料；3)造粒和陈腐；4)半干压成型；5)干燥；6)施釉；7)烧成：将干燥好坯体放入辊道窑中烧成，得到高强高铝质陶瓷薄板。本方法通过煅烧铝矾土代替工业氧化铝引入AlO以及通过煤系高岭土引入富集生长的短棒状莫来石实现增强陶瓷薄板强度的同时，还利用煅烧铝矾土本身的杂质TiO及外部添加的TiO降低了烧成温度，使制得的高强高铝质陶瓷薄板同时具备强度高和烧成温度低的特点，且节约了成本。
