'''Barit''', [[kemijska formula]] BaSO<sub>4</sub>, je glavni in najpogostejši [[barij]]ev [[mineral]]. Lahko je različno obarvan običajno pa je brezbarven ali bel. Ne razstaplja se v [[voda|vodi]] in [[kislina]]h. [[Specifična teža]] je 4.5 g-cm3, [[trdota]] 3- 3.5. Uporablja se v industriji keramike, gumarski industriji, in proizvodnji [[eksploziv]]a.
