Elongated Grain Growth Mechanism of Alumina Ceramics with Additives

摘要：

　　The elongated grain evolution of alumina ceramics doping with Al2O3-CaO-SiO2(CAS),Nb2O5,and 3Y-TZP was studied under pressureless sintering.From in-situ growth elongated grain cooperating with second phase to toughen the alumina ceramics,microstructure and sintering properties were firstly studied systematically.The effect of additives on the alumina ceramics with columnar grain were analyzed by means of TEM,SEM,XRD,etc.Basing on the analyzed sintering process by the principle of dynamics,the elongated grain growth mechanism was further studied.
