Abstract

A discussion of the relative merits and problems of using Ba(OH)2, BaO, and Ba as starting materials for the synthesis of barium titanate by the alkoxide method is presented. The Ba(OH)2 process is promising because it does not involve the synthesis of barium alkoxide, whereas the BaO (93% pure) process suffers from complex chemical reactions; the impurities in BaO cause unknown effects on the composition and properties of the final ceramic. Use of high‐purity Ba metal (99.99%) for the synthesis of barium alkoxide is more desirable since it results in high‐purity, ultrafine barium titanate powders.
