High-strength corrosion-resistant SiC refractory material and preparation method thereof
The invention discloses a high-strength corrosion-resistant SiC refractory material and a preparation method thereof. The SiC refractory material comprises the following raw materials in parts by weight: 80-95 parts of silicon carbide, 0.1-8 parts of ytterbium oxide and 3-15 parts of silica sol. The invention relates to a preparation method of a high-strength corrosion-resistant SiC refractory material, which comprises the following steps: uniformly mixing 80-95 parts of silicon carbide, 0.1-8 parts of ytterbium oxide and 3-15 parts of silica sol, carrying out compression molding under a certain pressure, drying, and sintering at the high temperature of 1200-1550 DEG C to obtain the high-strength corrosion-resistant SiC refractory material. The high-strength corrosion-resistant SiC refractory material prepared by the invention has the characteristics of small aperture, high strength and strong high-temperature H2O-O2 coupling corrosion resistance.
本发明公开了一种高强耐腐蚀SiC质耐火材料及其制备方法。SiC质耐火材料包括如下组分的原料：80‑95份碳化硅、0.1‑8份氧化镱和3‑15份的硅溶胶。高强耐腐蚀SiC质耐火材料的制备方法，将80‑95份碳化硅、0.1‑8份氧化镱和3‑15份的硅溶胶混合均匀，然后在一定压力下压制成型，烘干后经过1200‑1550℃高温烧成，制得高强耐腐蚀SiC质耐火材料。本发明制备的高强耐腐蚀SiC质耐火材料具有孔径小、强度大、抗高温H2O‑O2耦合腐蚀性能强的特点。
