We Manufacture Three Types of Lead Oxide
Lead Oxide Red (Red Lead)
Robinson International is one of the most trusted Red Lead manufacturers India that is efficiently thriving for the past three decades in this line of production and extending a wide array of high quality Red Lead chemically called Lead Tetra Oxide (Pb3O4). The Red Lead powder that we supply is in smooth reddish orange color and finds its extensive application as raw material in storage batteries and in paint manufacturing process. This apart, Red Lead forms the base for the manufacture of positive plates and tubular plates in Storage Batteries, in addition to glass, ceramic, rubber and plastic industries efficiently. Being a well reputed Red Lead Manufacturers India, we evince keen interest in maintaining transparency and business ethics in our dealings with our clients. We have installed the latest automatic Barton Plant and Red Lead furnaces in our manufacturing facility that is effectively utilized in the manufacture of Red Lead Oxide using Pure Lead as raw material having least purity of 99.98%. Our Red Lead conforms to IS: 57-1989 Type A, B and C.

Lead Oxide Yellow (Litharge)
Robinson International Litharge manufactures India and supplies Litharge that is known chemically as Lead Mono Oxide (PbO) is an odorless yellow colored powder. Our premium quality Litharge powder finds extensive usage in diverse manufacturing industry domains like ceramics, insecticides, lubricants, rubber, PVC, inorganic pigments, petroleum refining and so on. We are one of the leading Litharge manufacturers India and Litharge suppliers having streamlined manufacturing facility with fully automated Barton Plant having a heating capacity at 600°C temperature in the beginning manufacturing process and have installed Litharge furnaces for the second production phase. Our Litharge manufacturing process involves making use of Pure Lead as raw material with of 99.98% purity.
Process of Manufacturing Litharge
Making of Litharge involves a batch process. Under such process, the furnace needs to be heated up to a temperature between 575 to 600°C using a gas or an oil fired burner. Afterwards, the Lead Oxide is metered and fed into the furnace. The material fed into the furnace gets combined and agitated at the above temperature during the entire process. Since the process is exothermic, this involves lesser fuel consumption because of the exothermic process.
When the process goes on, negative draft is maintained inside the furnace and the negative draft helps in accessing fresh oxygen to the furnace. This helps to ensure that the litharge is lesser than 0.05% of metallic lead. Then the Litharge from the furnace is transferred to a crusher to break the agglomerates. This process is carried out at a temperature of 600 °C. Once this is done, the litharge is stored in silos with cooling facility.
