A New Method for the Preparation of Transparent AION Ceramic

摘要：

　　Transparent AION ceramics are prepared with single-phase AION powder synthesized from micron-sized aluminum and nano-sized alumina.The ceramics are prepared through sintering at the temperature of 1880℃ for 10,20 and 40 hours in flowing-nitrogen atmosphere,respectively.The effects of powder and temperature holding-time on transparent ceramic preparation and microstructure and transparency are investigated.The results show that all samples are transparent and of a single-phase AION and,with increasing holding-time,the average pore size and porosity decreases and consequently,the ceramics are dense and their transparency is improved.
