• Ceramics making [Category: Hobbies]
• Catalyst for the polymerization of formaldehyde to high molecular weight crystalline poly(oxymethylene) products; in PVC friction liners for pulleys or drive cables of hoisting engines; to improve bonding of polychloroprene to metals in wire-reinforced hoses, 10-25 parts of lead caronate are used in the elastomer; component of high pressure lubricating greases; component of high pressure lubricating greases; catalysts in the curing of moldable thermosetting silicone resins; in coating on vinyl chloride polymers to
• Prepared by passing CO2 into a cold dilute solution of lead acetate, or by shaking a suspension of a lead salt less soluble than the carbonate with ammonium carbonate at a low temperature to avoid formation of basic lead carbonate.
