“…It has the following chemical formula [26] and thermally decomposes [1,3], between about 450°C and 750°C in two stages, releasing only carbon dioxide, leaving a solid residue of magnesium oxide and calcium oxide. The thermal decomposition of mixtures of these minerals through endothermic release of carbon dioxide and water has led to several studies showing their potential applications, including fire retardant additives for polymer compounds [2,4,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46], controlling burning rates in cigarettes [47,48], and as a potential material for fighting forest fires [49][50][51][52][53]. Due to its high decomposition temperature it has been suggested [40,41,43] that huntite has little more influence than an inert diluent filler in terms of fire retardancy.…”
