Abstract

A thermalgravity analysis on the white precipitates obtained by solution reaction of lead nitrate and alkali with adding NaCl was presented. Two thermal absorption peaks on the thermal absorption curve correspond to decomposition of lead hydroxide nanorods and melting lead oxide nanorods. And the melted temperature of the lead oxide nanorods is about 700 ºC, it is obviously lower than that of body lead oxide. A serial of controlled thermal treatment experiments confirm these results. This gives a simple and effective strategy to obtain lead oxide nanorods by thermal treatment in the temperature range from 400ºC to 600ºC.
