Lead Oxide Plate Precipitates from Lead Nitrate Solution
In this paper, a simple and controllable method to fabricate - and -PbO is reported. Lead nitrate as precursor was dissolved in 50ml distilled water, and was heated to 80oC. Sodium chloride was added into the lead nitrate aqueous solution. During the process, -PbO deposition will be obtained when we add lead nitrate solutions with KOH pellets without chloride anion. When we add lead nitrate solutions with KOH pellets with a little chloride anion, there will produce -PbO deposition. Our results indicate that the concentration of chloride anion and temperature of reaction solution affects the crystal morphologies and modifications of lead monoxide plate precipitates from lead nitrate solution and we can selectively and controllably produce - or -PbO by this way.
