Synthesis And Sintering Of Large Batches Of Barium Zirconate Nanopowders

The acrylamide gelification process is a fast, inexpensive, reproducible and easily scaled up, chemical method for obtaining nanopowders of ~BaZr03 that can be used for sintering crucibles and many electronic applications. This method enables the production of 100g 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 deg C, making the fabrication of BaZr03 crucibles possible for many laboratories.
