    Accés restringit per política de l'editorial
    Low-grade magnesium hydroxide (LG-MH) is a solid by-product that undergoes an endothermic decomposition in the temperature range of 300–750 C. Due to its thermal behaviour and its lower cost relative to pure Mg(OH)2, ...
  • Chemically bonded cements formulated with by-products of magnesium oxide 

    Formosa Mitjans, Joan; Aranda, Ma; Chimenos Ribera, Josep Maria; Rosell Amigó, Juan Ramón; Ginés, O.; Fernández Renna, Ana Inés (2008-10)
    Article
    Accés obert
    The casting of magnesium and potassium phosphate (KMgPO4•6H2O; K-struvite) cements becomes possible after the aqueous reaction between magnesium oxide and potassium dihydrogen phosphate. This reaction is quite exothermic ...
