Calcium magnesium silicate

Higher resolution aluminium-27 and silicon-29 NMR spectroscopy of glasses and crystals along the join calcium magnesium silicate-calcium aluminium silicate (CaMgSijOj-CaAljSiO,). American Mineralogist, 71, 705-11. [Pg.183]

The chemical properties of copper, lead, lead-zinc, and zinc slags are essentially as ferrous silicates, whereas nickel slags are primarily calcium/magnesium silicates. Table 4.13 lists typical chemical compositions of these slags. [Pg.171]

The main crystalline phases were identified (see Figs. 1 2) and the contents of amorphous material were determined from selected bed samples by XRD. Main crystalline phases are Ca9(Al 0 g) calcium aluminium oxide, Ca8,2sNai.5(Al60]g) calcium sodium aluminium oxide, calcium magnesium silicate (diopside), calcium phosphide, and magnesium silicate (enstatite). [Pg.781]

The raw materials are blended and charged into the glass furnace, which is a refractory lined bath covered by a refractory roof. The furnace is heated to about 2000 °C by burners in the space above the molten glass. As the raw materials enter the bath, the carbonates decompose and evolve carbon dioxide, which helps to agitate the bath and to disperse the solids in the melt. The solids react to produce the sodium/calcium/magnesium silicate which is the principle constituent of most glasses. [Pg.100]

Lime fusion is based on the reaction of zircon with calda, or doloma, which yields calcium zirconium silicate, calcium zirconate, calcium silicate, zirconium oxide, calcium magnesium silicate and the mixtures thereof, according to the reaction conditions ... [Pg.30]
