• Huntite - Wikipedia

    en.wikipedia.org/wiki/Huntite Huntite is a carbonate mineral with the chemical formula Mg 3 Ca(CO 3) 4. Huntite crystallizes in the trigonal system and typically occurs as platy crystals and powdery masses. The most common industrial use of huntite is as a natural mixture with hydromagnesite as a flame retardant or fire retardant additive for polymers.

  • Hydromagnesite - Wikipedia

    en.wikipedia.org/wiki/Hydromagnesite Hydromagnesite is a hydrated magnesium carbonate mineral with the formula Mg 5 (CO 3) 4 (OH) 2 ·4H 2 O. . It generally occurs associated with the weathering products of magnesium containing minerals such as serpentine or brucite.It occurs as incrustations and vein or fracture fillings in ultramafic rocks and serpentinites.It occurs in hydrothermally altered dolomite and marble.

As a natural mineral product, it is inherently less expensive than precipitated ATH or MDH. Hydromagnesite has low aspect ratio but huntite is a medium aspect ratio platy material which alters polymer melt flow behavior and provides some reinforcement.
