Manganese antimonate powder as well as preparation method and application thereof
The invention discloses manganese antimonate powder as well as a preparation method and application thereof, and belongs to the technical field of inorganic material preparation. The preparation method comprises the following steps: ball-milling and drying a manganese source and an antimony source in a molar ratio of (1.8-2.2): 1, adding a eutectic solvent according to a molar ratio of a hydrogen bond acceptor to the manganese source of (0.5-1): 1, uniformly mixing, drying, crushing, and finally carrying out solid-phase sintering, crushing, washing and drying at 700-800 DEG C to obtain the submicron pure-phase manganese antimonate powder, the manganese source is one or more of manganese dioxide, manganese carbonate and manganese nitrate, and the antimony source is one or two of antimony trioxide and antimony pentoxide; the deep-eutectic solvent takes choline chloride as a hydrogen bond acceptor and one of malonic acid, urea and acetamide as a hydrogen bond donor. The manganese antimonate powder prepared by the method disclosed by the invention is of a standard tetragonal crystal structure, is uniform in granularity and good in monodispersity, and is suitable for being used as a dopant of a high-power piezoelectric ceramic material.
本发明公开了一种锑酸锰粉体、其制备方法和应用，属于无机材料制备技术领域。本发明将摩尔比为1.8~2.2：1的锰源和锑源经球磨烘干后，按照氢键受体与锰源摩尔比0.5~1:1加入低共熔溶剂，混合均匀后烘干、粉碎，最后经过700‑800℃固相烧结、粉碎、洗涤和烘干，得到亚微米级纯相锑酸锰粉体；所述锰源为二氧化锰，碳酸锰，硝酸锰中的一种或几种，锑源为三氧化二锑、五氧化二锑中的一种或两种；所述低共熔溶剂是以氯化胆碱作为氢键受体，以丙二酸、尿素、乙酰胺中的一种作为氢键供体。本发明方法所制备的锑酸锰粉体，为标准的四方相晶体结构，粒度均匀、单分散性好，适合作为大功率压电陶瓷材料的掺杂物使用。
