웹2024년 3월 28일 · Bassanite is a calcium sulfate mineral with formula CaSO 4 · 1 2 H 2 O or 2CaSO 4 ·H 2 O. In other words it has half a water molecule per CaSO 4 unit, hence its … 웹2024년 4월 11일 · Oilfield scale inhibition is the process of preventing the formation of scale from blocking or hindering fluid flow through pipelines, valves, and pumps used in oil production and processing. Scale inhibitors (SIs) are a class of specialty chemicals that are used to slow or prevent scaling in water systems. Oilfield scaling is the precipitation and …

웹2015년 3월 12일 · Abstract. Bassanite is a metastable but industrially important form of calcium sulfate, which is commonly produced by heating of gypsum. Here we show that pure bassanite can also be obtained at ambient conditions by quenching aqueous CaSO 4 solutions in ethanol. This highlights that organic solvents can actually induce the formation … 웹2012년 4월 6일 · Combined with the observation that the hemihydrate (bassanite) precipitated as a precursor to the more hydrated phase (gypsum), these findings contradict the generally accepted bulk solubility behavior ( 7, 13) for calcium sulfates. Bulk bassanite is metastable across the whole temperature range ( Fig. 3A and fig. S3). remove ants from dog food
