- Lead Oxide / Grey Oxide
R R Metal Industries is the largest Lead Oxide Manufacturer in India. The Greyish color Lead oxide is also known as lead sub oxide, grey oxide, battery oxide. The chemical formulae of Lead suboxide are (2PbO.Pb) The Lead Sub-oxide (Grey Oxide) is widely used in the production process of Lead Acid Storage Battery plates, Electroplating Anode, in addition to Sulphuric Acid Tank Liners.
As a Leading Lead Sub-oxide Manufacturer We always used Only the Pure Lead With the Minimum Purity Level Of 99.97% as raw material in the Production of Grey Oxide. The Grey Oxide is produced in the Ball Mill Plant & The process is an endothermic process in this process we focus our attention in maintaining the temperature in the level of 115-135 C For Smooth Conversion of lead to Lead Sub-oxide,the Ball Mill is cooled with the Constant flow of air and also with the water spraying system Contolled through a Solenoid Valve.
