Research Results For 'Silicate'

EGYPTIAN BLUE

Egyptian blue was the first pigment prepared by artificial means. It is a crystalline silicate of copper that produces a fine rich blue colour that was much used in fresco work.

FUSIBLE PORCELAIN

Fusible porcelain is a silicate of alumina and soda obtained from cryolite and sand, fused and worked as glass.

MAGNESIUM SILICATE

Magnesium Silicate is a fine, white, odourless, tasteless powder with variable hydration. It is insoluble in both water and alcohol and is used as a rubber filler, a bleaching agent, and odour absorber and in the manufacture of paints and resins.
Research Magnesium Silicate

SILICATE

A silicate (sillic acid) is a compound formed by the combining of silica (SiO2) and water in various proportions.

WATER-GLASS

Water-glass or soluble glass is an aqueous solution of sodium or potassium silicate. Upon exposure to the air water-glass solidifies, and is used for painting frescoes, as a fire-retardant paint and for pickling eggs.

ZIRCONIUM

Zirconium is a lustrous, greyish-white, strong, ductile, metallic element, with the symbol Zr. It occurs in nature as the mineral zircon (zirconium silicate), from which it is obtained commercially. It is used in some ceramics, alloys for wire and filaments, steel manufacture, and nuclear reactors, where its low neutron absorption is advantageous.

AGARIC MINERAL

Agaric Mineral or mountain-meal is one of the purest of the native carbonates of lime. It is found chiefly in the clefts of rocks and at the bottom of some lakes in a loose or semi-indurated form resembling a fungus. The name is also applied to a stone of loose consistence found in Tuscany, of which bricks may be made so light as to float in water, and of which the ancients are supposed to have made their floating bricks. It is a hydrated silicate of magnesium, mixed with lime, alumina, and a small quantity of iron.

ALLANITE

Allanite is a silicate containing a large amount of cerium. It is usually black in colour, opaque, and is related to epidote in form and composition. It occurs as a minor constituent of many igneous rocks and is frequently associated with epidote. Found in some magnetic bodies. It has the formulae (Ce,Ca,Y)2(Al,Fe)3(SiO4) 3(OH) and a relative hardness of 6. It is named after T. Allan who discovered it.

ALUM SCHIST

Alum schist or alum slate is a variety of shale or clay slate, containing iron pyrites, the decomposition of which leads to the formation of alum, which often effloresces on the rock. It is named on account of much alum being prepared from it. It is greyish, bluish, or iron-black in colour; often possessed of a glossy or shining lustre; chiefly composed of clay (silicate of alumina), with variable proportions of sulphide of iron (iron pyrites), lime, bitumen, and magnesia.

ANORTHOCLASE

Anorthoclase is a feldspar closely related to orthoclase, but triclinic. It is chiefly a silicate of sodium, potassium, and aluminium.
