Boron phosphate reinforced quartziferous material and preparation method thereof
The invention relates to a boron phosphate reinforced quartziferous material and a preparation method thereof. According to the technical scheme, the preparation method comprises the following steps: mixing 80-84 wt% of natural quartz, 10-14 wt% of fused quartz, 1-5 wt% of boron phosphate, 2-4 wt% of sodium carboxymethyl cellulose and 1-3 wt% of water, grinding, and ageing to obtain a mixture; carrying out mechanical pressing under the condition of 70-80 MPa, and drying to obtain a boron phosphate reinforced quartzite material blank; and heating the boron phosphate reinforced quartziferous material blank to 1000-1300 DEG C, keeping the temperature for 1-3 hours, and naturally cooling to obtain the boron phosphate reinforced quartziferous material. The method has the characteristics of simple process flow, low cost and environmental friendliness; the prepared boron phosphate reinforced quartzite material is high in volume density, small in apparent porosity and high in breaking strength.
本发明涉及一种磷酸硼增强石英质材料及其制备方法。其技术方案是：将80～84wt％的天然石英、10～14wt％的熔融石英、1～5wt％的磷酸硼、2～4wt％的羧甲基纤维素钠和1～3wt％的水混合，研磨，困料，制得混合料；再于70～80MPa条件下机压成型，干燥，制得磷酸硼增强石英质材料坯体；然后将所述磷酸硼增强石英质材料坯体加热至1000～1300℃，保温1～3小时，自然冷却，制得磷酸硼增强石英质材料。本发明具有工艺流程简单、成本低和环境友好的特点；所制备的磷酸硼增强石英质材料体积密度大、显气孔率小和抗折强度大。
