Lead-free relaxor ferroelectric ceramic material and preparation method thereof

ZHANG XIAN / PU YONGPING / ZHANG LEI / ZHANG JINBO / NING YATING / SHANG YANGCHAO / OUYANG TAO / JI JIAMIN

The invention relates to a lead-free relaxor ferroelectric ceramic material, wherein the stoichiometric formula of the lead-free relaxor ferroelectric ceramic material is (1-x)(0.94Na[0.5]Bi[0.5]TiO[3]-0.06BaTiO[3])-xBa[0.85]Ca[0.15]Ti[0.9]Zr[0.1]O[3], x is equal to 0, 0.1, 0.2, 0.3, 0.4 and 0.5, and x is molar mass percent. The material is prepared by mixing, ball-milling and drying BaTiO3 powder, Na0.5Bi0.5TiO3 powder and Ba0.85Ca0.15Ti0.9Zr0.1O3 powder which are obtained by ball-milling, calcining and crushing. The lead-free relaxor ferroelectric ceramic material has the advantages of high density, small and uniform grain size, and the method has the advantages of simple preparation process, environmental friendliness and the like.

一种无铅弛豫铁电体陶瓷材料，其配方化学计量式为(1‑x)(0.94Na0.5Bi0.5TiO3‑0.06BaTiO3)‑xBa0.85Ca0.15Ti0.9Zr0.1O3，其中x＝0,0.1,0.2,0.3,0.4,0.5，其中x为摩尔质量百分比。由经球磨煅烧粉碎后所得的BaTiO3粉体、Na0.5Bi0.5TiO3粉体和Ba0.85Ca0.15Ti0.9Zr0.1O3粉体混合球磨烘干后制得。具有致密度高、晶粒尺寸细小且均匀、制备工艺简单、环境友好等优点。
