Gypsos

CaSO4

GYPSOS is certified, eco friendly anhydrous calcium sulphate (anhydrite), produced by Fluorsid in its four fluorochemical sites of Cagliari, Porto Marghera, Treviglio and Odda.

Gypsos is obtained from the reaction of dried acid grade Fluorspar (CaF2 97%) and Sulphuric Acid (H2SO4) during the production of Hydrogen Fluoride (HF): CaF2(solid) + H2SO4(liquid) —› 2HF (gas) + CaSO4(solid)

Prior to be sent to further processes or storage, GYPSOS is neutralized with a small excess of lime.

Its physical and mechanical features can be adjusted depending on the specific needs, to make it suitable for different applications, in building, cement and fertilizer industries.

In the building industry, it is widely used for the production of self-levelling screeds. GYPSOS milled is also an excellent alternative to cement in many non-structural concretes and mortars, as well as in various indoor applications as plasters, blocks for fire system solutions and aerated concrete.

In the cement industry, it is used as an alternative to natural gypsum, FGD gypsum and phosphogypsum, as an additive to regulate cement’s setting time.

In fertilizers’ production, it is an excellent calcium and SO3-bearing raw material. GYPSOS based fertilizers help to improve the soil structure and workability and balance the uptake of nutrients and minerals.
