摘要
以高炉炉渣为原料,用高温自蔓延燃烧工艺合成了较为纯净的单相(Ca,Mg)α-sialon粉料(简称炉渣α-sialon粉),并用无压和热压烧结工艺将炉渣α-sialon粉烧结成了炉渣α-sialon陶瓷。对炉渣α-sialon陶瓷的力学性能进行了检测。结果表明,炉渣α-sialon陶瓷有较好的力学性能,优良的抗冲刷性能和抗酸腐蚀性能。
(Ca,Mg) a-sialon powder containing rather pure α-sialon phase (abbreviated as salg α-sialon) was synthesized successfully by self-propagating high-temperature synthesis (SHS) technique, using slag as a raw material. The slag α-sialon powder was pressure-less and hot-pressed and the mechanical properties, the scour resistance to YAG, SiC, the erosion resistance to acid of slag a-sialon ceramics were studied. The results show that slag α-sialon ceramics have good mechanical properties and excellent scour resistance to YAG and SiC and erosion resistance to acid.
