Chemische Eigenschaften
Basic lead carbonate forms white hexagonal crystals; it decomposes when heated to 400 °C. It is insoluble in water and alcohol, slightly soluble in carbonated water, and soluble in nitric acid.
Chemische Eigenschaften
dense white powder
Verwenden
Lead(II) carbonate is used in ceramic glaze and exterior paint.
Verwenden
Lead(II) carbonate basic can be used as pigment in oil paints and water colors; in cements; for making putty and lead carbonate paper; in the processing of parchment.
Definition
Acid-soluble, heavy, white powder or crystalline substance, insoluble in water and alco- hol.
Vorbereitung Methode
Basic Lead Carbonate is produced by several methods, in which soluble lead acetate is treated with carbon dioxide. For example, in the Thompson-Stewart process, an aqueous slurry of finely divided lead metal or monoxide, or a mixture of both, is treated with acetic acid in the presence of air and carbon dioxide. High quality, very fine particle-size basic lead carbonate is produced, ranging in carbonate content from 62 to 65% (vs 68.9% PbCO3, theoretical).
synthetische
Many commercial processes have been developed for manufacturing basic lead carbonate. These include: Thomson-Stewart process, Carter process, and Dutch process. The method of preparation involves treating lead with acetic acid vapors in the presence of carbon dioxide at 60°C. In the Thomson-Stewart process, finely divided lead monoxide or lead metal is mixed with water to give aqueous slurry, which is then mixed with acetic acid in the presence of air and carbon dioxide. All these processes are slow, taking weeks to obtain products of desired composition.
Basic lead carbonate also is precipitated by dissolving lead monoxide in lead(II) acetate solution, and treating the solution with carbon dioxide. It also is produced by electrolysis of sodium nitrate or sodium acetate using lead anode and then precipitating out the product by adding sodium carbonate.
