calcined powder meaning in English

煅烧粉末

Compared with cmo and cpm , scm had many advantages not only simpling preparation process , lowing calcining and sintering temperatures , shorting reacting time , but also preparing ceramics with excellent dielectric properties . with identical calcining conditions , the content of perovskite phase in calcined powders prepared by scm was much higher than that by cmo , what ' s more , by scm , the sintered ceramics had clear crystal boundaries , large - sized crystal grains and high density
、 pbo bi仙混合助烧剂（摩尔比为1 ： 1 ： 1 ）都达到了理想的助烧效果，可将烧结温度降低到900oc ，且介电性能优良，样品介电常数分别不小于is000和22000 ，介电损耗分别不大于0
In the systems of pfw - pt , the effects of excess pbo , and fe2o3 , the content pt on the phase structure , microstructure and dielectric properties of pfw ceramics were investigated respectively in detail . the results revealed that by adding excess pbo and fe2o3 , not only the content of perovskite phase in calcined powders and sintered ceramics increased , but also the dielectric constant increased , especially
和“作为pw pt陶瓷助烧剂的研究中发现， pbo作为助烧剂，属于液相烧结机制，在烧结中后期， pbo会停留在晶粒表面，因稀释铁电相而恶化介电性能。
