LITEMIX FOR REFRACTORY APPLICATION

Keltech Energies Ltd., Perlite Division offer the following products which are used as lightweight and insulating ingredients in the manufacture of refractories.

A lightweight expanded perlite coarse aggregate made from naturally occurring volcanic rock having good insulating property. Essentially alumino silicate, inert with high compatibility with cement.

Colour - White Bulk Density - 100 – 150 kgs per cu. m. Particle size - 4 mm - 0.150 mm Moisture content - 0.5%

SiO2 | 71 – 75% Al2O3 | 12 – 18% Fe2O3 | 0.5 – 1.0% CaO | 0.5 – 1.0% N2 | 3 - 4% K2O | 4 – 5%

Used as a lightweight – insulating ingredient with low iron content in castables. Such refractories were originally developed for catalytic reformers, which required product with less than 1% iron content to avoid poisoning of catalyst. Because of its ability to withstand atmospheres containing carbon monoxide and high percentage of hydrogen its use has spread to other applications requiring a high purity material of lightweight and high insulating efficiency to ensure economic linings. Mainly used in sponge iron, petrochemical chemical and refinery catalytic reformers, boiler top decks and arc furnace insulation etc. Maximum service temperature 1100 C.
