Lead compounds are poisons. 55) form at temperature 170K (103C). 0000005392 00000 n Adding PbO to industrial ceramics (as well as glass) makes the materials more magnetically and electrically inert (by raising their Curie temperature) and it is often used for this purpose. These salts are all poorly soluble in water. At 580C, the reaction is complete. if lime is replaced by lead oxide (PbO) and if potash (K2O) is used as a partial replacement for soda, lead-alkali-silicate glasses result that have lower softening points than lime glasses. If the heating occurs in presence of air, the compounds decomposes to give the monoxide and the sulfate. In organic synthesis, lead dioxide anodes were applied for the production of glyoxylic acid from oxalic acid in a sulfuric acid electrolyte.[13].
