Composite oxide refractory material based on BaO and ZrO2 system and preparation method thereof
The invention discloses a barium-zirconium oxide complex-phase refractory material, which is characterized in that the barium-zirconium oxide complex-phase refractory material has chemical components of BaO and ZrO2 systems, and the adopted raw material composition ratio is as follows: zirconium dioxide: barium carbonate = 1: 1-1: 2 according to molar percentage. The barium zirconium oxide multiphase refractory material is a two-phase coexisting composite phase of a BaZrO3 phase and a Ba2ZrO4 phase; the size of the BaZrO3 phase is greater than that of the Ba2ZrO4 phase; the BaZrO3 phase is in an irregular polygonal form, and the Ba2ZrO4 phase is in a spherical particle form. According to the prepared barium-zirconium oxide complex-phase refractory material, by forming the composite barium-containing phase and the composite zirconium-containing phase, the refractoriness and density of the refractory material are improved, the apparent porosity is reduced, the compression strength is improved, and the comprehensive performance is improved.
本发明公开了一种钡锆氧化物复相耐火材料，其特征在于，具有BaO和ZrO2体系的化学成分组成，按摩尔百分比计算，采用原料组成比例为：二氧化锆:碳酸钡＝1:1‑1:2；所述钡锆氧化物复相耐火材料为BaZrO3相和Ba2ZrO4相的二相共存复合相；所述BaZrO3相的尺寸大于所述Ba2ZrO4相的尺寸；所述BaZrO3相为不规则多边形态，所述Ba2ZrO4相为球状颗粒形态。本发明所制得的钡锆氧化物复相耐火材料通过形成复合含钡相和复合含锆相，提高耐火材料的耐火度，密度，降低显气孔率，提高耐压强度，提升综合性能。
