Preparation method and application of pyrochlore ceramic material Er2Ti2O7
The invention discloses a preparation method and application of a pyrochlore ceramic material Er2Ti2O7, and relates to the field of ceramic materials.The method comprises the steps that 0.004 mole of erbium oxide Er2O3 and titanium dioxide TiO2 powder are taken, and a sample Er2O3 + 2TiO2 = Er2Ti2O7 is weighed according to the mole ratio of 1: 2; pre-burning the weighed powder in a corundum crucible at 1000 DEG C, and calcining for 10 hours; adding deionized water into the pre-sintered powder, and carrying out ball milling in a ball mill to uniformly mix the powder; placing the ball-milled material in an electrothermal blowing drying box, keeping the temperature of 105 DEG C constant for 4 hours, drying the material, and sieving the dried powder material by a stainless steel sieve; putting the sieved powder material into an agate mortar, adding a polyvinyl alcohol ceramic adhesive, mixing, and grinding by using a grinding rod, so that the adhesive and the powder are uniformly mixed; and sieving the ground material with a stainless steel sieve. The ceramic material is prepared through forming and high-temperature sintering. The alloy has the advantages of high melting point, high hardness, high wear resistance, oxidation resistance and the like, and has good application performance.
本发明公开了一种烧绿石陶瓷材料Er2Ti2O7的的制备方法及应用，涉及陶瓷材料领域，所述方法包括取0.004摩尔的氧化铒Er2O3、二氧化钛TiO2粉末按照1:2的摩尔比称量样品Er2O3+2TiO2＝Er2Ti2O7；称量后的粉末在刚玉坩埚中预烧1000℃，煅烧10小时；将预烧后的粉末加去离子水在球磨机中球磨，使其混合均匀；将球磨后的材料放在电热鼓风干燥箱中设置105℃的温度恒温4小时，使其烘干，将烘干后的粉体材料经过不锈钢筛子过筛；过筛之后的粉体材料放入玛瑙研钵中加聚乙烯醇陶瓷胶混合并用研磨棒研磨，使得胶和粉体混合均匀；将研磨之后的材料用不锈钢筛子过筛。本发明经过成型和高温烧结，制备出陶瓷材料。它具有高熔点、高硬度、高耐磨性、耐氧化等优点，具有良好的应用性能。
