The fire retardant behaviour of huntite and hydromagnesite …
Alternatively huntite is contributing some as yet unidentified fire retardant behaviour. As the ratio of hydromagnesite to huntite increases to 40% there is a steady increase in oxygen index but at around 40% the oxygen index plateaus with no further significant increase, even at ratios of hydromagnesite [57].

Properties of gypsum particleboard with added mineral dolomite
Fortunately, there are some fire retardant fillers that can be used. These are categorized as inorganic and organic flame-retardants depending on their chemical na- ture. Mineral dolomite has an ideal chemical composition of CaMg(CO3)2 and belongs to a symmetry structure group in the trigonal subsystem of the hexagonal crystal system (Morrow 1982).
