Titanium nitride coated high titanium corundum and preparation method and application thereof
The invention belongs to the field of materials, and particularly relates to titanium nitride coated high-titanium corundum and a preparation method and application thereof, the titanium nitride coated high-titanium corundum comprises a titanium nitride coating layer and a coated main body material, the main body material comprises the following components in percentage by mass: 83-96.5% of Al2O3, 3-16.5% of Ti2O3 and impurities, wherein Ti2O3 and Al2O3 in the main body material respectively exist in an independent phase form. The invention aims to solve the problems of high smelting cost and poor performance of existing corundum and brown fused alumina abrasive materials. When alumina ore is used for smelting corundum and brown fused alumina, TiO2 impurities are difficult to remove, and the process cost for removing the titanium impurities is high. According to the preparation method, the high-titanium alumina is selected as the raw material, and titanium-containing impurities in the high-titanium alumina are selectively reserved in the smelting process, so that the titanium-containing impurities finally exist in a corundum matrix in the form of Ti2O3, the high-titanium corundum (Ti2O3-Al2O3) material is prepared, and the smelting cost is greatly reduced.
本发明属于材料领域，尤其涉及一种氮化钛包覆高钛刚玉及其制备方法和应用一种氮化钛包覆高钛刚玉，包括氮化钛包覆层和被包覆的主体材料，所述主体材料包括如下质量百分比的组分Al2O383～96.5％、Ti2O33‑16.5％及杂质，其中主体材料中Ti2O3和Al2O3各自以独立相形式存在。本发明针对现有刚玉、棕刚玉磨料冶炼成本较高、性能不佳。以矾土矿冶炼刚玉、棕刚玉时，其中的TiO2杂质难以去除，除去钛杂质工艺成本高。本发明选取高钛矾土为原料，并在冶炼过程中选择保留其中的含钛杂质，使其最终以Ti2O3形式赋存于刚玉基体中，制取高钛刚玉(Ti2O3‑Al2O3)材料，大大降低了冶炼成本。
