Uses of Sillimanite Powder for Mining Industries

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 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.
