A clear and transparent solution that is colorless or nearly colorless. Odorless, non-volatile. The relative density ranged from 1. 7 to 1. 74.
results from the reaction of fluoroboric acid with lead oxide.
plating solutions for lead and its alloys.
inhalation, oral or transdermal absorption is harmful to the body. The eyes, skin, mucous membranes and respiratory tract have a strong stimulating effect, can cause eye and skin burns. In the body affect a variety of enzyme activity and sugar metabolism, causing calcium and phosphorus metabolism disorders and skeletal fluorosis. Long-term exposure can lead poisoning. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from the alkali, not mixed storage.
