Lead (II) Oxide / Litharge (Yellow Lead Oxide), 99.5% purity, PbO, 100 GMS and up

Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula PbO. PbO occurs in two polymorphs, one litharge having a tetragonal crystal structure and the other massicot having an orthorhombic crystal structure. Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components.

Litharge is one of the natural mineral forms of lead(II) oxide, PbO. Litharge is a secondary mineral which forms from the oxidation of galena ores. It forms as coatings and encrustations with internal tetragonal crystal structure. It is dimorphous with the orthorhombic form massicot. It forms soft (Mohs hardness of 2), red, greasy-appearing crusts with a very high specific gravity of 9.14–9.35. PbO may be prepared by heating lead metal in air at approx. 600°C (lead melts at only 300°C). At this temperature it is also the end product of oxidation of other lead oxides in air. [1] This is often done with a set of bellows pumping air over molten lead and causing the oxidized product to slip/ fall off the top into a receptacle where it quickly solidifies in minute scales.[2]

PbO2 –(293 °C)→ Pb12O19 –(351 °C)→ Pb12O17 –(375 °C)→ Pb3O4 –(605 °C)→ PbO

Historically, the term "litharge" has been combined to refer to other similar substances. For example, litharge of gold is litharge mixed with red lead, giving it a red color; litharge of silver is litharge that comes as a by-product of separating silver from lead; litharge of bismuth is a similar result of the oxidation of bismuth. The term has also been used as a synonym for white lead or red lead.[3]

Returns & exchanges

I can not offer returns, refunds or exchanges on chemical materials due to the fact that there is no guarantee that the material has not been tampered with and I can not resell it to someone else with confidence that I have the same materials that was originally purchased from my supplier. Therefore I repeat there are NO returns on chemical materials.

I offer exchanges only on Ceramic art for equal or greater value item. The buyer is required to pay to return the original item shipping and the new item shipping as well as 25% restocking fee. Also for clarity the Free shipping is no longer applicable on exchanged items. The new item will be shipped when the original item is received intact and the additional fees have been paid.
No item will be exchanged of a lesser value item with the buyer expecting refund.
