The phase composition of samples prepared under hydrothermal conditions at 200Β°C from a suspension of mixtures of CaO, quartz and magnesite has been studied. When I0, 20, 30 and 50 wt % of CaO were substituted by magnesite, the mole ratio CaO/SiO 2 being 0,83 and 1,20 -chiefly tober~w)rite, gyrolite
Water suspension of mixtures of CaO, and quartz (CaO/SiO o = 1,2; 1,6 and 2,0) in which I0-50 wt % CaO were substituted by dolomite, were hydrothermally treated at 20OΒ°C. X-ray phase analysis of reaction products showed that chiefly scawtite and partly calcium-and magnesium silicate hydrates were fo
