Meyerhofferite is a calcium hydrated borate mineral with formula Ca2(H3B3O7)2·4H2O and occurs as white complex acicular to crude crystals in sedimentary or lake-bed borate deposits. Simultaneous thermogravimetric analysis (TG) and derivative thermal analysis were performed. The TG curve shows a main decomposition at 195 °C followed by a second decomposition centered at about 436 °C. The total loss of mass is 28.1 % upon heating up to 1000 °C. The decomposition of meyerhofferite is also followed… Expand
