Product Description

 

Great Quality Sillimanite Use as Refractory Materials
Sillimanite is a kind of high-temperature metamorphic mineral, commonly found in the contact zone between igneous rocks and argillaceous rocks, the crystal is needle or columnar, the aggregate is radial or fibrous, belongs to the rhombotic crystal system, the color is generally grayish green, light green, grayish yellow, light yellow, brown, light brown, white or colorless, ductile. The melting point of sillimanite is 1850ºC, the density is 3.2~3.27g/em, the hardness is 6.5~7.5, the coefficient of thermal expansion is low, the chemical composition is relatively pure, the impurity content is very small, the chemical properties are very stable, insoluble in water and acid, and the corrosion resistance of metal and glass melt slag is good. It has good thermal shock resistance, slag erosion resistance, mechanical strength, wear resistance, chemical corrosion resistance and high fire resistance.
 
Advantages

 

Sillimanite decomposed at high temperature to produce mullite and silica, accompanied by a certain volume expansion, so the product with sillimanite as the main raw material or the addition of sillimanite to other products, the use of its volume expansion effect can effectively offset the volume shrinkage of the product in the high temperature sintering process, limit the local stress, prevent and passivate the generation of cracks. The thermal shock resistance of the product is improved, the mechanical peeling is reduced, the performance of the product is improved, and the service life of the product is extended.
 

Application

High-purity sillimanite can be used to smelt aluminum-silicon alloys to make aircraft and ships, or to make ceramic components such as spark plugs, thermocouple bushings, and heap collapses. High-purity sillimanite can be used to smelt aluminum-silicon alloys to make aircraft and ships, or to make ceramic components such as spark plugs, thermocouple bushings, and heap collapses. The conversion temperature of sillimanite is high, and it is difficult to compensate the shrinkage of refractory at low temperature. Therefore, sillimanite is suitable for refractory materials sintered at higher temperatures. For example, synthetic mullite is used as coarse aggregate, natural sillimanite is used as fine aggregate, and ground sillimanite, high alumina soil and kaolin are used as matrix to manufacture sintered refractory materials for glass kilns by mud casting. Of course, kyanite group minerals are also used to make refractory materials.
