On the other hand, heating hydrated sulfate above 150°C yields magnesium oxysulfate, a hydrolysis reaction. No dehydration or thermal decomposition occurs. [Pg.537]

U.S. Pat. No. 5,767,178 [24] describes a thermoset (or a cold-set) composition of a phenol-aldehyde, a urea-aldehyde, or a polyurethane, mixed with cellulose fibers and latex, containing magnesium oxychloride or magnesium oxysulfate to improve fire resistance of the resulting composite. [Pg.80]

Magnesium oxyacetate binder may be produced by combining calcined magnesia with magnesium acetate [Mg(CH3.COO)2] (Harmuth et al., 1998). The setting characteristics of the binder are similar to those of the magnesium oxysulfate cement. The binder develops considerable strength. The nature of the reaction products has not yet been studied. [Pg.239]

Magnesium oxysulfate cement pastes can be produced through reaction of MgO and an aqueous solution of MgS04 7H20.t Alternatively magnesium chloride solutions can be added to calciiun sulfates or calcium phosphate-sulfate mixtures. The presence of phosphates enhances the water resistance of this cement system. [Pg.360]

Four magnesium oxysulfate complexes are formed in the MgO-MgS04-H20 system in the temperature range, 30-120°C. These are ... [Pg.361]

Magnesium oxysulfate cement systems have many similar characteristics to those of magnesium oxychloride cement systems. They are, however, less sensitive to elevated temperatures, hence more suitable to some industrial processes incompatible with the use of magnesium oxychloride cement. [Pg.361]

Magnesium oxysulfate cement pastes are generally considered to be weaker than oxychloride pastes. Beaudoin and Ramachandran exam-... [Pg.361]
