Method for preparation of lead fluorozirconates
Description
An accelerated and simplified method anhydrous lead fluorozirconate preparation via lead nitrate solution interaction with ammonium fluorozirconates at the ratio of the reagents 5:1 and at 1.5-1.9-multiple excess of hydrofluoric acid is suggested. At 80-90 deg for 2.5-3 h the product Pb5ZrF6 is formed with the yield of 90.0-92.4 %
