摘要
本文研究了助烧剂Ｙ２Ｏ３对ＧＰＳＺｒＯ２（３ｍｏｌ％Ｙ－ＴＺＰ）－Ｓｉ３Ｎ４系统中ＺｒＯ２相结构的影响。研究结果表明：ＺｒＯ２（Ｙ－ＴＺＰ）－Ｓｉ３Ｎ４系统中不添加Ｙ２Ｏ３助烧剂，ＺｒＯ２相组成主要以ｍ－ＺｒＯ２形式存在，并有少量氮稳定ＺｒＯ２；ＺｒＯ２（Ｙ－ＴＺＰ）－Ｓｉ３Ｎ４系统中添加５ｗｔ％Ｙ２Ｏ３助烧剂，ＺｒＯ２相组成为ｃ－ＺｒＯ２、不能相变的过稳定ｔ－ＺｒＯ２。
ffect of sintering aid Y_2O_3 on the phase composition of ZrO_2 in ZrO_2(Y-TZP)-Si_3N_4 system was studied.The experimental results indicated that phase composition of ZrO_2 were m-ZrO_2 and a small amount of N-stabilized ZrO_2 if no sintering aid Y_2O_3 was added into the ZrO_2(Y-TZP)-Si_3N_4 System;c-ZrO_2 or non transformable t-ZrO_2 if 5wt% Y_2O_3 as sintering aid was added into the ZrO_2(Y-TZP)-Si_3N_4 System.
