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 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 1450degreesC, making the fabrication of BaZrO3 crucibles possible for many laboratories.
