On this Wikipedia the language links are at the top of the page across from the article title. Lead oxide (PbO) exists in two crystalline modifications: red tetragonal (-PbO) and yellow orthorhombic (-PbO). The electrodeposition is carried out galvanostatically, by applying a current of about 100A/m2 for about 30 minutes. Chlorination of plumbite solutions causes the formation of lead's +4 oxidation state. During thermal oxidation of lead, first a PbO layer forms on the metal surface, followed by an oxidation reaction that proceeds via a solid .

A mixture of PbO with glycerine sets to a hard, waterproof cement that has been used to join the flat glass sides and bottoms of aquariums, and was also once used to seal glass panels in window frames. Preparation of MnO2-modified graphite sorbents from spent Li-ion batteries for lead, cadmium and silver contaminated water treatment. The drawback of this method for the production of lead dioxide anodes is its softness, especially compared to the hard and brittle PbO2 which has a Mohs hardness of 5.5. It dissolves in dilute nitric acid, hydrochloric . It is a dense, soft metal that is very resistant to corrosion and poorly conductive compared to other metals. The reaction of Pb3O4 with nitric acid produces the dioxide. Separation of lead oxide using electrolysis to form lead dioxide on the anode and subsequent EDTA titration is a popular method, applied to 50-100mg of PbO after nitric acid-hydrofluoric acid treatment of the glass in a platinum dish. By the 1770s the use of white paint was general, and a positive electrode of lead oxide (PbO2). [7] Heating mixtures of the monoxide and the sulfide forms the metal.[2].

Thermal decomposition of lead(II) nitrate or lead(II) carbonate also results in the formation of PbO: PbO is produced on a large scale as an intermediate product in refining raw lead ores into metallic lead. [6] Both allotropes are black-brown in color and always contain some water, which cannot be removed, as heating also causes decomposition (to PbO and Pb3O4). High concentrations can be absorbed through skin as well, and it is important to follow safety precautions when working with lead-based paint. The chloride of this oxidation state is formed only with difficulty and decomposes readily into lead(II) chloride and chlorine gas. exists in two crystalline forms. 3 Pb + 8 H + + 8 NO 3 3 Pb 2+ + 6 NO .
