Synthesis of Plumbum Titanate used in PTCR in chotic liquid

摘要: 以电子级金红石二氧化钛、硝酸钡为原料 ,氨水 -二氧化碳为混合沉淀剂 ,在悬浊液中合成出碳酸铅与二氧化钛的均匀混合物 ,经煅烧制备 Pb Ti O3 基质粉体 .产品纯度≥ 99.5 % ,Pb O/ Ti O2 (摩尔比 ) =1

Abstract: Plumbum titanate which is used in PTCR is prepared in chaotic liquid.TiO 2 in rutile mould and Ba(NO 3) 2 are used as starting material,NH 3 CO 2 are used as mixed precipitator.The powder of plumbum titanate were synthesized with this technology.The results are that,the purity≥99.5%,PbO/TiO 2(molar/molar)=1.
