Sillimanite is mineral composed of Aluminum and silicon pent oxide. It was named after the chemist B. Silliman (1779-1824). Sillimanite occurs throughout the world in metamorphosed peri-aluminous sedimentary rocks. Sillimanite Powder is widely used all over the world for manufacturing of Refractory Bricks, Iron Foundries, Spark Plugs, Glass, and Chemicals.

Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. It is one of the three allotropic varieties of mineral corresponding to the formula Al2O3 SiO2. The other two are an adalusite and Kyanite. They all contain 63.2% Al2O3 and 36.8% SiO2. They are distinguished from one another by their modes of occurrence and physical and optical properties. Anand Talc placed in Rajasthan state of India, who is a leading Sillimanite Powder Manufacture in India. It offers you Sillimanite Powder for industrial uses in various industries.
A common variety of Sillimanite is known as Fibrolite, so named because the Mineral appears like a bunch of fibers twisted together when viewed under thin section or even by the naked eye. Both the fibrous and traditional forms of Sillimanite are common in Metamorphosed Sedimentary Rocks. We are best Sillimanite Powder Exporter in Udaipur , Rajasthan, and India.
The sillimanite mineral in raw or calcined form is specially used in manufacturing of refractory bricks, shapes, castings, monolithics, ramming and gunning mixtures.
Anand Talc offers you Sillimanite Powder for various industrial applications; it is one of the best Mining Mineral Exporter in India. They are used in manufacturing of spark plugs and other insulated materials, when mixed with china-clay. We make them available in Pure Powder form as well as we also customize them as per the buyer’s requirements. There are several uses of sillimanite powdersillimanite powder in various mining industries as in form of raw material in powder form .They are as Follows:-
*) Sillimanite Powder used as Refractory Products:-Between 1545º to 1550ºC, as it changes over to mullite there is a fairly rapid permanent expansion of 2-3%. The mineral thus shows negligible expansion while changing over to mullite and can hence be used without pre-calcinations.
Minimum increase in porosity upon heating: One outstanding feature of sillimanite is that the volume porosity of grains hardly exceeds 6% after heating. Moreover, if heating is prolonged, it tends to decrease as a consequence of vitrification. It has low electrical conductivity. Anand talc is an established supplier of raw, refractory grade sillimanite; we are a best Talc Powder Manufacturers in India. Our sillimanite gives successful results whether used raw or post calcinations.
*) Sillimanite used in Ceramic:- Anand Talc offers high purity sillimanite powder, containing minimum basic impurities like sodium and calcium to encourage the formation of the needle shape mullite in ceramic manufacture. We are Sillimanite Powder Exporter for Ceramic Industry in Udaipur .
*) Sillimanite Powder in Electrical Components: – We offers you best form of sillimanite powder for industrial use, that containing minimum iron oxide, which otherwise alter the electrical conductivity of the product.

Product Description
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.
