<P> Because of the hazardous nature of lead (II) nitrate, there is a preference for using alternatives in industrial applications . In the formerly major application of lead paints, it has largely been replaced by titanium dioxide . Other historical applications of lead (II) nitrate, such as in matches and fireworks, have declined or ceased as well . Current applications of lead (II) nitrate include use as a heat stabiliser in nylon and polyesters, as a coating for photothermographic paper, and in rodenticides . </P> <P> On a laboratory scale, lead (II) nitrate provides one of two convenient and reliable sources of dinitrogen tetroxide . By carefully drying lead (II) nitrate and then heating it in a steel vessel, nitrogen dioxide is produced, which dimerizes into the desired compound . </P> <Dl> <Dd> 2 NO ⇌ N O </Dd> </Dl> <Dd> 2 NO ⇌ N O </Dd>
