Subsequently, the plastic surface is treated with a metal salt solution, containing at least one salt from the following group: 'Cobalt salt, silver salt, tin salt, lead salt'.

The polycrystalline layer may be a lead salt semiconductor material.

These detonators are made without any lead salts and sensitive primary explosives.

In the process lead acetate or other lead salt is produced which is converted to high purity litharge by precipitation with a base.

When these amounts of mercury salt and lead salt were administered, the synergistic toxicity of these two toxins killed 100 in 100 mice:
