Assay Litharge

DECENT Assay Litharge is a highly refined and critically important chemical reagent, specifically developed to ensure superior accuracy in the determination of gold and silver through the fire assay method. As a special, high-purity form of lead oxide (PbO), its quality is paramount to the integrity of precious metal analysis. In the demanding environment of assay laboratories, where even trace impurities can compromise results, the exceptional purity of Assay Litharge makes it an indispensable fluxing agent. It efficiently collects precious metals during the fusion stage, forming a lead button that encapsulates the gold and silver, enabling their precise separation and quantification.

DECENT Group’s commitment to delivering premium-grade analytical reagents guarantees that our Assay Litharge provides reliable and consistent performance, solidifying its role as a cornerstone for accurate and trustworthy precious metal assays worldwide.

The efficacy of Assay Litharge stems from its unique chemical properties and high purity, making it vital for successful fire assay operations. During the fusion process, it acts as a powerful collector, reacting with metal oxides and silicates to form a molten slag, while simultaneously binding with gold and silver to form a lead alloy. Its distinct reddish-orange color, characteristic of lead(II) oxide, serves as an initial visual indicator, though it can change upon light exposure. With a melting point of approximately 888-890°C and a high relative density, Assay Litharge ensures efficient separation of the lead button from the lighter slag.

DECENT’s meticulously produced Assay Litharge consistently meets stringent purity standards, including specifications like Lead(II)oxide 99% and Lead(II) oxide 99+%, ensuring minimal interference from contaminants. This adherence to high-quality benchmarks provides assayers with the confidence required for critical analysis, directly contributing to the precision and reliability of gold and silver determination.
