Карбонат бария

Карбонат бария (BaCO₃) — это белый кристаллический порошок без запаха, нерастворимый в воде и этаноле, но растворимый в кислотах; он термически устойчив и разлагается при температуре выше 1300 °C с выделением углекислого газа. С химической точки зрения это неорганическая соль щелочноземельного металла, относящаяся к классу карбонатов. В промышленности карбонат бария широко применяется как исходное сырьё для получения других соединений бария — в частности, оксида бария, пероксида бария и нитрата бария — а также как компонент в производстве специальных стёкол, керамики и электротехнических ферритов. Его ключевое применение связано с электронной промышленностью (в качестве добавки в диэлектрические материалы и магнитные компоненты), а также с производством пигментов, огнеупорных материалов и некоторых типов полимерных наполнителей.
