GYPSUM

2010
GyPSuM is a 3-D model of mantle shear wave (S) speeds, compressional wave (P) speeds, and density. The model is developed through simultaneous inversion of seismic body wave travel times (P and S) and geodynamic observations while using realistic mineral physics parameters linking wave speeds and density. Geodynamic observations include the global free

Salts in gypsum and calcined gypsum

Journal of Applied Chemistry and Biotechnology, 1973
AbstractChloride in a number of samples of gypsum and calcined gypsum has been determined by Surkevicius's method and by nephelometry. Results from the former method are confirmed. Sodium was determined by atomic absorption spectroscopy and the content found to be considerably greater than the equivalent of the chloride.

Estimation of gypsum hemihydrate content in recycled gypsums derived from gypsum boards

Journal of Material Cycles and Waste Management, 2014
In order to utilize reclaimed gypsums (gypsum board waste) derived from waste plasterboards as geo-materials, thermal behaviors of the reclaimed gypsums and reagent gypsum are investigated in this paper. Furthermore, simple density measuring method of judging quality of the reclaimed gypsums is examined to determine the gypsum hemihydrate content.

Raman intensities near gypsum–bassanite transition in natural gypsum

Journal of Raman Spectroscopy, 1999
The phase transition sequence of natural gypsum (CaSO4 · 2H2O) was studied by Raman spectroscopy in the temperature range 300–550 K. The reduced peak intensity of the symmetric stretching mode around 1008 cm−1 varied anomalously during the gypsum–bassanite transition.
