UltraCarb is a multifunctional hybrid of two minerals from a natural deposit: hydromagnesite (hydrated magnesium carbonate) and huntite (magnesium calcium carbonate).
Magnesite and Hydromagnesite are found visually in small outcrops within 12 km off northeastern Naein and along the Naein fault and the resulting minor faults, that is, the lands between the Serar to Soucheh farms.
2+] to produce magnesian calcite, or its precipitation with carbonate or silicate to produce, respectively, hydromagnesite and nesquehonite or sepiolite (Suarez 2005).
This could be attributed to brucite or hydromagnesite formation at higher curing ages, since sepiolite has a magnesium compound present in its composition.
DENIZLI, Apr 28, 2011 (TUR) -- Turkey exports untite and hydromagnesite mineral to 16 countries.
Hydromagnesite can grow in such mounded masses of radiating crystals, but the crystals themselves are linear and quite thin, and no evidence of breakage is seen in our examples (Deer et al.
Massive white crusts of a magnesium mineral which regularly accompany stichtite are probably hydromagnesite.
The minerals considered include calcite, gypsum, hydromagnesite, nesquehonite, and sepiolite.
Depending on the intended industrial mineral use, natural brucite competes for its share of the market with synthetic brucite, commonly referred to in the manufacturing industry by its chemical formula, magnesium hydroxide, and with other minerals and compounds such as magnesite, dolomite, huntite, hydromagnesite, MgO, CaO, zeolites and others.
Hydromagnesite is found as water-clear, terminated blades to 1 cm in cavities, and as flattened fans and rosettes on fracture surfaces.
A mixture of huntite and hydromagnesite, Ultracarb imparts a flame retardant action when mixed into polymers by means of the evolution of carbon dioxide and water at temperatures above 225 [degrees] C.
