Lead Sub Oxide
99.97% – 99.985% Pure Lead
Lead Sub Oxide is produced from lead in the ball mill plant & the process is an endothermic reaction. In this process, heat is generated and the temperature of oxide is increased to control the temperature within the range of 115 to 135°C.
The Lead Sub Oxide is used extensively in the preparation of plates for lead acid batteries
