Examples
- Combined core - shell method with scm , pmw - pnn - pt ceramics with core - shell structure , which have excellent dielectric temperature stability , were successfully prepared . the new mechanism of improving temperature stability of dielectric properties was put forward . the main contents are lis ted as bellows : in the systems of pmn - pt , the effects of the chemical reactivities of the starting materials such as soluble mg - salts instead of mgo , pb - salts instead of pbo and ti ( oc4h9 ) 4 instead of tio2 respectively on the formation of perovskite phase were investigated in detail
Scm法与cpm法的工艺相比，工艺简单，预烧温度和烧结温度低，反应时间短；陶瓷致密，介电性能比cmo法和cpm法明显得到改善，而且在没有pt存在时，仍可制得纯钙钛矿结构的pmn基、 pnn基、 pfw基陶瓷。
