Refractory Cement is a kind of quality castable refractory material with refractoriness that is not less than 1580℃. This unshaped refractory has many excellent properties of thermal shock resistance, strong acid resistance and high wear resistance, which can be used to cement refractory bricks or repair linings of all kinds of industrial furnace.
Acidic Refractory Uses. Because the properties of acidic refractory are quite different from basic refractory, the acidic refractory uses are also different from that of basic refractory.The anti slag corrosion performance, refractoriness under load, the volume change at high temperature burning and thermal shock resistant ability determines the using temperature of acidic refractory.

This part of ISO 21068 specifies analytical techniques for the determination of change in mass by thermal treatment at specified temperatures, and methods for the determination of the total carbon content, free carbon, silicon carbide, silicon, total silica and free silica content of silicon-carbide-containing raw materials and refractory products.
3.1 The oxidation of silicon carbide refractories at elevated temperatures is an important consideration in the appliion of these refractories. The product of oxidation is amorphous silica or cristobalite, depending upon the temperature at which oxidation takes place. This oxide formation is associated with expansion and degradation of strength.
Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
