Cement-bonding-free silicon carbide ceramic as well as preparation method and application thereof
The invention provides a cement-bonding-free silicon carbide ceramic as well as a preparation method and application thereof. The cement-bonding-free silicon carbide ceramic is prepared from the following raw materials in parts by weight: 3-6 parts of silica-alumina sol; 60-80 parts by weight of silicon carbide particles; 6-12 parts by weight of silicon carbide micro powder; 8-12 parts by weight of silica powder; 10-15 parts by weight of alumina micro powder; 1-3 parts by weight of carbon black; 0.5-1 part by weight of dispersed aluminum oxide; 0.1 to 0.5 part by weight of explosion-proof fiber; 0.1-0.5 part by weight of a dispersing water reducing agent; and 4-8 parts by weight of water. Compared with the prior art, the cement-bonding-free silicon carbide ceramic provided by the invention adopts specific components with specific contents to realize relatively good overall interaction, and the obtained cement-bonding-free silicon carbide ceramic can keep excellent high-temperature performance at 1500 DEG C and is suitable for being applied to combustors.
本发明提供了一种无水泥结合碳化硅陶瓷及其制备方法和应用；所述无水泥结合碳化硅陶瓷由包括以下组分的原料制备而成：硅铝溶胶3～6重量份；碳化硅颗粒60～80重量份；碳化硅微粉6～12重量份；硅微粉8～12重量份；氧化铝微粉10～15重量份；炭黑1～3重量份；分散氧化铝0.5～1重量份；防爆纤维0.1～0.5重量份；分散减水剂0.1～0.5重量份；水4～8重量份。与现有技术相比，本发明提供的无水泥结合碳化硅陶瓷，采用特定含量的特定组分，实现整体较好的相互作用，得到的无水泥结合碳化硅陶瓷在1500℃可保持优异的高温性能，适合在燃烧器中应用。
