01.06.2014· Most silica refractories (crystalline or amorphous) are produced from silica-rich minerals such as quartz and flint and have SiO 2 contents of 98 wt% or higher. Because of the relatively low theoretical density of cristobalite and tridymite (2.3 g/cm 3), silica bricks are often used to construct arched furnace crowns .
A moulded silicon carbide-based refractory article is obtained by reaction sintering of a mixture containing silicon carbide grains, silicon metal and 0.05-1.5% boron, at temperature of 1100-1700°C to form silicon nitride (Si 3 N 4 ) binder. The weight ratio Si 3 N 4 /SiC of the sintered material is in the range of 0.05-0.45.

01.01.1991· Most industrial refractories are composed of metal oxides or of carbon, graphite or silicon carbide. Other newer refractory materials such as carbides, nitrides, borides and silicides are generally used only for special appliions, because of economic considerations. The most commonly used refractory oxides are SiO 2, Al 2 O 3, MgO, CaO, Cr 2

Silicon carbide is one of the major artificial inorganic materials widely applied in the manufacture of abrasive tools, high-temperature radiators, refractory ceramics as well as in metallurgy. The largest amount of silicon carbide in the world industry is produced by the method suggested by Acheson at the end of the 19th century [1]. The
A sintered material based on silicon carbide (SiC) reactively sintered between 1,100° C. and 1,700° C. to form a silicon nitride binder (Si 3 N 4 ), intended in particular for fabriing an aluminum electrolysis cell, including 0.05% to 1.5% of boron, the Si 3 N 4 /SiC weight ratio being in the range 0.05 to 0.45.
Silicon carbide’s resistance to high temperature and thermal shock is the property that allows SiC to be used in the manufacturing of fire bricks and other refractory materials. The decomposition of silicon carbide starts at 2000°C [2]. Conductivity. If SiC is purified, its behaviour manifests that of an electrical insulator.
Refractory materials are commonly grouped into (1) those containing mainly aluminosilies; (2) those made predominantly of silica; (3) those made of magnesite, dolomite, or chrome ore, termed basic refractories (because of their chemical behavior); and (4) a miscellaneous egory usually referred to as special refractories.

30.04.2015· Silicon carbide is another refractory material. It is very strong at high temperatures, but will burn in the presence of oxygen, if the protective silica coating comes off. Refractories must be chosen according to the temperature inside the unit and the chemical nature of the material being processed.
