Monoclinic celsian ceramic material based on solid-phase synthesis method and preparation method of monoclinic celsian ceramic material
The invention relates to a monoclinic celsian ceramic material based on a solid-phase synthesis method and a preparation method of the monoclinic celsian ceramic material. According to the technical scheme, the preparation method comprises the following steps: burdening, mixing, ball-milling and drying according to the molar ratio of oxides contained in raw materials of BaO: Al2O3: SiO2 being 1: (1-1.1): 2 to prepare mixed powder I; the raw material is a mixture of a barium source, an aluminum-silicon source and a silicon source supplement; wherein the barium source is barium carbonate or barium hydroxide, the aluminum-silicon source is one of mullite, kyanite, andalusite and sillimanite, and the silicon source supplement is fused quartz. And carrying out mechanical pressing on the mixed powder I at 50-80MPa, drying, heating to 1200-1500 DEG C, carrying out heat preservation for 3-6 hours, and naturally cooling to obtain the monoclinic celsian ceramic material based on the solid-phase synthesis method. The method has the characteristics of simple process, short production period and low cost, the ceramic material with the main crystal phase of monoclinic celsian can be synthesized at lower temperature and shorter heat preservation time, and the prepared product is high in phase purity, small in volume density and large in apparent porosity.
