This compound is still widely used in detergents for domestic and industrial use. Washington DC. The material can be obtained also from sodium sulfate (melting point 884C) with carbon as a reducing agent: In 1990, 4 million tons of alkali metal silicates were produced. It is particularly useful when drill holes pass through argillaceous formations containing swelling clay minerals such as smectite or montmorillonite. Brass hulls for shotgun shells were superseded by paper hulls starting around 1877. The most common "builder" used to be sodium trimetaphosphate. chloride, sodium hydroxide, and glycerol. The effects of "hard" water calcium or magnesium ions are minimized by the addition of "builders". #T?O#lzkj,y^Fn/j^"Xt;dGXJ^YDU{xZtd>M#xD q-r6 ^"%#:P=V7v:xof\vEGXHI0{X&^^' ]KkMK@rxpX X#+C=VTQ^bQ{KOUO}(D@7 q??hSjc`XHh\HI:"nC@ORQsy2m,{}mPpIvx6cz/f~Z]k#g7Q3>TL/VZzB0b{^) D\sv4 5CHU'!@hW24r"4$\qKaQlF+VAZ7 2]\Z6jNGglh^|QRDp,(0('+mJ6Waz$c~(*p|PPtS_({Hj+%zcGMK[rju7DU$x2cbZ The common process of purifying soap involves removal of sodium [5] When the powder was exposed to moist air, it gradually formed a viscous liquid, which Glauber called "Oleum oder Liquor Silicum, Aren, vel Crystallorum" (i.e., oil or solution of silica, sand or quartz crystal). The phosphates react with the calcium or magnesium ions and keeps them in solution but away from the soap molecule. The sodium Sodium silicate solutions can also be used as a spin-on adhesive layer to bond glass to glass [19] or silicon oxide covered silicon wafers to one another. In this application, the sodium silicate (6070%) is typically mixed with kaolin (40-30%), an aluminium silicate mineral, to make the sodium silicate "glued" joint opaque. Their electrical double layer collapses due to the increase of ionic strength caused by the addition of sodium silicate (doubly negatively charged anion accompanied by two sodium cations) and they subsequently aggregate.
