MINERAL COMPOSITION BASED ON CALCIUM AND MAGNESIUM CARBONATES MIXED SOLID PHASE, PREPARATION METHOD AND USE THEREOF Russian patent published in 2016 - IPC C04B2/10 C04B14/26 

FIELD: physics.

SUBSTANCE: invention relates to mineral composition based on calcium and magnesium carbonates mixed solid phase, to method of its production and application. Mineral composition based on calcium and magnesium carbonates mixed solid phase, consisting of crystalline calcium and magnesium fractions, crystallized in form of plates, wherein crystals of calcium and magnesium fractions are combined in form of combined units, wherein said units themselves are at least partially agglomerated, and said calcium fraction contains at least one carbonate, selected from group consisting of calcite, aragonite and mixtures thereof, and said magnesium fraction contains hydromagnesite in plate-like form, wherein said mixed solid phase has bulk density, measured according to norm EN 459.2, less than or equal to 250 kg/m³ and more or equal to 80 kg/m³.

EFFECT: technical result consists in reduction of bulk density and heat conductivity.
