Dè a th 'annBarium hydroxide agus barium hydrowxide octahydrateair a chleachdadh?
Gu gnìomhach,barium Hydroxideair a chleachdadh mar ro-ruitheadair barium eile. Tha am monohydrate air a chleachdadh gus a bhith a 'dehydrate agus a' toirt air falbh sulfate bho ghrunn thoraidhean. Mar a bhios cleachdadh obair-lann, barium hydroxide air an cleachdadh ann an ceimigeachd anailis airson tiomnadh luchd-riaghlaidh lag, gu sònraichte suids organ organas.Barium Hydroxide octahydarteair a chleachdadh gu farsaing ann a bhith a 'saothrachadh barium salann agus todhar organach barium; mar chuir-ris ann an gnìomhachas na peatrail; Ann an saothrachadh alkali, glainne; Ann an synthetic rubair gòrach, ann am barrancion creimichean, puinnseanan; leigheas meud goileadair; Bidh luchd-glanaidh goileadair, ann an gnìomhachas siùcair, socraich oils beathaich is glasraich, uisge-sùcan, glainneachan, peant am mullach; Taiste airson companachd CO2; Air a chleachdadh airson tasgaidhean reamhar agus leaghadh silicate.
