Oct 09, 2018

Lead oxide can usually be prepared by air oxidation of molten lead, lower than 470°c when the Red Square crystals.In the lead (ⅱ) salt solution by adding an appropriate amount of alkali or ammonia, the white lead hydroxide precipitation, and then at a temperature below 100°c to the loss of lead hydroxide, lead oxide yellow orthogonal crystals, water loss at 100°c, can be Red Square crystals.
