Celestite. Celestite (SrSO 4) is a member of the barite group of minerals and its structure is similar to that of barite, with Sr taking the place of Ba. There is a complete solid-solution series between BaSO 4 and SrSO 4, but solid solution of CaSO 4 in SrSO 4 is limited. Natural specimens, however, rarely contain more than 2% or 3% of the Ba ...Web

The reactive layer consisted of celestite (or celestine, SrSO 4) with a bimodal grain size distribution (<63 μm and 125–400 μm). A barium chloride solution was then injected into the flow cell, leading to fast dissolution and replacement of celestite by barite (or baryte, BaSO 4).
