原始语种摘要: Abstract(#br)The crystallization of four Y 2 O 3 -Al 2 O 3 -SiO 2 (YAS) glasses were investigated to prepare YAS glass ceramics precipitated singly/mainly Y 2 Si 2 O 7 or Y 4.67 (SiO 4 ) 3 O apatite, and to explore the crystallization difference between the stoichiometric parent glass (SPG) and non-stoichiometric parent glass (NSPG). The DSC results revealed that glass locating at the higher liquidus surface temperature has lower crystallization peak temperature, which indicating that the corresponding glass has higher crystallization potential to crystallize easily. Crystallization of the NSPG samples is along surface and caused by phase separation, while SPG sample is the surface crystallization at the first exothermic peak temperature and overall crystallization at the second...
