Synthesis and Sintering of Large Batches of Barium Zirconate Nanopowders

Abstract

The acrylamide gelification process is a fast, inexpensive, reproducible, and easily scaled up chemical method for obtaining nanopowders of BaZrO3 that can be used for sintering crucibles and many electronic applications. This method enables the production of 100 g of high‐purity powders in one run, using simple laboratory equipment and low‐cost raw materials. The gelification process, synthesis temperature, and gas conditions required for obtaining high‐quality powders were the subjects of the present study. Fine powders were sintered to full density at 1450°C, making the fabrication of BaZrO3 crucibles possible for many laboratories.
