Useful:

• Physical Properties: Bright-red crystalline substance or amorphous powder; density 9.1 g/cm3; decomposes on heating to 500°C, melts at 830°C under pressure and oxygen; insoluble in water and alcohol; soluble in glacial acetic acid, hot hydrochloric acid, and a dilute nitric acid-hydrogen peroxide mixture.
• Uses: Lead tetroxide has many applications. The most important use is in paint and storage-batteries. It is used as a pigment in corrosion-protecting paints for steel surfaces. It also is used in positive battery plates; in colored glasses and ceramics; in glass sealants for television picture tubes; in propellants and explosives; in radiation shields for x-rays and gamma rays; in the vulcanization of rubber; in glass-writing pencils; in adhesives for tire cords; in foaming agents and waterproofing materials; in plasters and ointments; in lead dioxide matches; and as a catalyst for oxidation of carbon monoxide in exhausts. Plasters and ointments; manufacture of colorless glass; glaze for faience; flux for porcelain painting, protective paint for iron and steel; oil-color for ship paints, varnishes; coloring rubber; cement for glass, gas and steam pipes; storage batteries; pencils for writing on glass; manufacture of lead peroxide, matches. Red lead (Pb3O4) is a brilliant red-orange colored synthetic inorganic pigment used mainly as a protective priming coat for steel work rather than a coloring pigment in paints. The toxic nature of this pigment restricts its use in modern coating systems. Lead(II,IV) oxide is used to prepare colorless glass, faience glaze, porcelain painting flux, iron and steel coatings, rubber pigment and in glass cement. It is also used in gas and steam pipes, storage batteries, writing on glass and to make lead peroxide and matches. It is associated with linseed oil and used as a thick, long-lasting anti-corrosive paint. It gives better water resistant properties by replacing magnesium oxide. Further, it is used in the manufacture of lead glass and rustproof primer paints. In addition to this, it acts as a pigment for primer paints for iron objects.
• Description: Lead oxide, a range of products that is formed by the oxidation of Lead in the forms of liquid and solid. Lead oxides are basically an oxide’s family varying in color (grey/green, red, and yellow), in degree of oxidation (PbO, Pb3O4, PbO2) and in crystal structure (in forms of PbO, orthogonal and tetragonal).Lead oxide is a term that can be either Lead monoxide or litharge Lead tetroxide or Red Lead or Gray or Black oxide which is a mixture of 30 percent metallic Lead and 70 percent Lead monoxide. Black Lead is made for specific use in Lead acid storage batteries manufacturing. Due to large use in the Lead acid battery industry, Lead monoxide is one of the most important compounds of Lead, based on volume. Due to its electrical and electronic properties, litharge is also used in various components for different types of use like capacitors, electro photographic plates, and Video tubes, even in ferromagnetic and ferroelectric materials. Their wide range of chemical and physical properties, Lead oxides have been know and used worldwide since before the ancient Romans.
