Abstract

A calcination stage or a high-energy milling is needed before sintering the BaTi4O9 and Ba2Ti9O20 ceramics via traditional oxide route or mechanochemical process. While in this reaction-sintering process, the calcining stage or the high-energy milling was bypassed and a mixture of raw material powders for BaTi4O9 and Ba2Ti9O20 ceramics were pressed and sintered directly. This process is simpler than the traditional oxide route or the mechanochemical process.
