Use

Lead monoxide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. Aluminum carbide is oxidized with incandescence on warming with lead oxide, [Mellor, 1946, Vol. 5, 872]. Mixtures of lead oxide with aluminum powder(as with other metals: sodium, zirconium) give a violent explosions, [Mellor, 1946, Vol. 5, 217, 1941].
