Product Description Product DescriptionYellow Lead is a kind of yellow or yellowish brown powder, its specific density is 9.53 g/cm3, melting point is 888°C, boiling point is 1470°C. Heated to 300-500°C, changes into Red 1ead; With the temperature going on, changes into Yellow Lead again. It doesn't dissolve in water and alcohol, but dissolves in glacial acetic acid easily; it is poisonous while dissolving in nitric ac1d.We are the Chinese premier manufacturer and supplier of quality, gold free flux and litharge. Our quality system guarantees the levels of gold in the fire assay flux are less than 1-1.5ppb in the litharge component of the flux, making it ideal for low level assay work. The raw materials are certified for the use of fire test flow, the main ones are litharge or lead oxide with SGS certified amounts of gold <1 ppb and Silver<1 ppm. In addition is used Borax anhydrous, sodium carbonate, silicon oxide, fluorite, and other elements to order of each customer. For each batch that is made for a given customer, a counter sample is left, which is kept for three months.High level of Quality Control at each stage of productionPackaged to your requirementPrompt international shippingConsultation available as neededCounter samples kept 3 monthsTechnical specification for core material litharge with SGS reportAu< 1PPB Ag<0.5PPMComponent StandardLithargePurity:99.9%Ag≤0.2ppmAu≤2ppmSoda Ash DenNaCO3≥99.2%BoraxB203%: 68.5-69.4Equivalent Na2B07%:99.0-100.3Na20%: 30.5-30.9H20 % ≤1.0SO4 ppm≤150Fe ppm≤40Silica200mesh SiO2≥99.5%Silver NitrateAR gradePackaging & ShippingPackage with 25kgs woven bags or plastic drums, or as your request.
