【摘要】：采用硅樹脂RSN-6018為陶瓷先驅(qū)體,并引入一定比例的預(yù)固化硅樹脂,在N_2氣氛下于1200℃裂解轉(zhuǎn)化制備組分單一、孔結(jié)構(gòu)可控以及陶瓷產(chǎn)率高的硅氧碳(Si-O-C)多孔陶瓷,研究了預(yù)固化硅樹脂含量對Si-O-C多孔陶瓷微觀形貌和性能的影響。結(jié)果表明:預(yù)固化硅樹脂的加入可有效調(diào)節(jié)Si-O-C多孔陶瓷的孔形貌、孔徑以及氣孔率,當(dāng)預(yù)固化硅樹脂含量低于90wt%時,隨著預(yù)固化硅樹脂含量的增加,孔結(jié)構(gòu)從貫通圓孔變?yōu)轭w粒"搭接"貫通孔,再變?yōu)轭w粒堆積孔,且氣孔率增大;而體積收縮減小,陶瓷產(chǎn)率提高;耐壓強(qiáng)度在27.9~17.5 MPa之間。
