Abstract

Abstract: Some factors that affect the behavior of sol-gel process, such as pH value, H₂O concentration and heating temperature were investigated. TG-DTAand XRD analysised the procedure of dried gels with increasing temperature and the structure of as-calcined powders. The results indicated that the crystallizing temperature of BaNd₂Ti₅O₁₄was 509℃ and the size of the crystallized powders calcined at 800℃ for 2h was 50nm.

Key words: gelation, autocombustion, BaNd₂Ti₅O₁₄, crystallize
