Beta'-Sialon-AlN-TiC composite ceramic material and preparation method thereof
The invention discloses a beta '-Sialon-AlN-TiC composite ceramic material and a preparation method thereof. The beta'-Sialon-AlN-TiC composite ceramic material is prepared from the following raw material components in percentage by mass: 17.21 to 32.28 percent of titanium-containing blast furnace slag, 22.47 to 28.35 percent of iron tailings, 19.43 to 35.82 percent of red mud and 18.2 to 33.87 percent of a reducing agent. The preparation process comprises the following steps: crushing, ball-milling, drying, sieving, blending carbon, uniformly mixing, carrying out compression molding, carrying out carbon thermal reduction nitridation, and removing carbon to obtain the beta'-Sialon-AlN-TiC composite ceramic material. The obtained composite powder has good corrosion resistance and stable high-temperature strength and chemical properties. According to the method disclosed by the invention, the recovery values and effects of elements in the titanium-containing blast furnace slag, the iron tailings and the red mud are fully exerted, the process is simple, the synthesized composite ceramic material integrates the excellent properties of beta'-Sialon, AlN and TiC, and the advantages are complementary, so that an effective way is provided for resource utilization of titanium-containing blast furnace slag, iron tailings and red mud, the added value of the product is improved, and the production cost of the Sialon ceramic material is reduced.
本发明公开了一种β’‑Sialon‑AlN‑TiC复合陶瓷材料及制备方法，其原料以质量分数计包括以下组分：含钛高炉渣17.21‑32.28％，铁尾矿22.47‑28.35％，赤泥19.43‑35.82％，还原剂18.2‑33.87％。制备工艺流程为：破碎、球磨、干燥、过筛、配碳混匀、模压成型、碳热还原氮化和除碳即可得到β’‑Sialon‑AlN‑TiC复合陶瓷材料。本发明获得的复合粉体具有有良好的耐蚀性、高温强度和化学性质稳定。本发明充分发挥含钛高炉渣、铁尾矿和赤泥中元素的回收价值和作用，且工艺简单，合成的复相陶瓷材料集β’‑Sialon、AlN、和TiC的优良性能于一身，三者之间优势互补，这为含钛高炉渣、铁尾矿和赤泥资源化利用提供了一项有效途径，提高产品附加值，降低Sialon陶瓷材料生产成本。
