Ba (Mg1/3Ta2/3) O3 powder and preparation method thereof
The invention relates to the field of ceramic materials, in particular to Ba (Mg1/3Ta2/3) O3 powder and a preparation method thereof. Mixing a tantalum-containing inorganic substance, a barium-containing inorganic substance and a magnesium-containing inorganic substance with an alkali solution to obtain a mixed solution; carrying out a hydrothermal reaction on the mixed solution at 150-250 DEG C for 10-40 h, and then taking a precipitate in a reaction product; and freeze-drying the precipitate to obtain powder. A tantalum-containing inorganic substance, a barium-containing inorganic substance and a magnesium-containing inorganic substance are adopted as starting raw materials and are mixed with an alkali solution, a hydrothermal reaction is carried out to synthesize BMT powder, and the BMT powder is prepared into powder through freeze drying. The primary particles of the BMT powder obtained by the technical scheme are spherical or sphere-like, the particle size is smaller, the primary particles are agglomerated, and the particle size is more uniform; and the material has higher density and better activity. According to the method, high-temperature sintering is not needed, the process difficulty is reduced, energy is saved, preparation is faster, and industrial application is facilitated.
本申请涉及陶瓷材料领域，涉及一种Ba(Mg1/3Ta2/3)O3粉体及其制备方法。将含钽的无机物、含钡的无机物和含镁的无机物与碱溶液混合，得到混合液；将混合液于150℃～250℃水热反应10h～40h，然后取反应产物中的沉淀物；将沉淀物冷冻干燥为粉体。通过采用含钽的无机物、含钡的无机物和含镁的无机物作为起始原料，与碱溶液混合，进行水热反应合成BMT粉体，并采用冷冻干燥将其制备为粉体。上述技术方案得到的BMT粉体一次颗粒粒径为球形或类球形，粒径更小，一次颗粒之间为团聚，粒径更均匀；材料致密度更高，具有更优的活性。该方法不需要高温烧结，降低了工艺难度，节约了能源，制备更快，有利于工业化应用。
