The global anhydrite market is segmented into soil treatment, construction, fertilizers, industrial applications, drying agents, and others.
The properties a filler offers are largely determined by its own physical and chemical characteristics. Several types of fillers used in plastics are alumina trihydrate, kaolin clay, calcium carbonate, talc etc. Carbon black and silica (precipitated, highly dispersed) are mainly used as fillers in elastomers.
A process is disclosed for making dead burn calcium sulfate anhydrite.

Nov 01, 2013· The filler size was estimated using an Alpine vibrator. The squeeze flow testing was done according to EN 1015-2, EN 1015-3 and EN 13279-2. The metallic plate was 300 mm in diameter; the mould ring 60 mm high, 100 mm in diameter at the base and 70 mm at the top.
Powdered anhydrite has also been found as a filler in the gesso grosso ground layers of Italian paintings and polychromed sculpture. Currently, the colorless, inert pigment is often used as a filler in paper, paints, and plastics.
Statistical analysis showed that both filler loading (P = 0.0092) and CA contents (P = 0.0330) had significant effects on tensile strength. Tensile strength might be reduced due to the poor adhesion between the polar natural filler and nonpolar plastic matrix. The addition, MAPE coupling agent improved the tensile strength of the composites.
