Bricks

Kyanex Shapes are highly volume stable at elevated temperatures. Besides, it has also very low impurities such as Iron Oxide, Titania and Alkalies. They have a very good resistance to thermal shocks. "Kyanex" an ideal choice for critical high temperature applications. Kyanex shapes ensures a dense uniform structure, after careful drying the shapes and sintering at high temperatures.

Kyanex is the best choice for Burner Blocks, Refractory Quarls, and Burner Throat Tiles as they must have a low Iron-Oxide to withstand spalling due to Carbon Monoxide attack. These shapes are also subjected to sharp thermal gradients, therefore they need to have excellent thermal spalling resistance. Hence shapes made out of Kyanex are ideally suited for the above application areas.

Also, our Element Holding Bricks offer low iron contamination in industry application.

Xlite Insulating Bricks (High Temperature Energy Efficient Shapes)

Xlite series of insulating bricks are specially formulated with independent pores so as to ensure maximum insulating efficiency. These bricks are suitable for hot face insulation since gas permeation is prevented. Apart from low thermal conductivity, bricks have low density, high strength, high PCE and low iron content.

Xlite is a unique development made with energy saving as the prime consideration. Xlite is a foamed Sillimanite shaped refractory - a hybrid of Sillimanite refractory insulation brick incorporating the best insulating properties. Sillimanite being highly volume stable at elevated temperatures, extremely intricate shapes can be made out of Xlite with close dimensional tolerances. Xlite being foamed, has strengths greater than any conventional insulation brick of corresponding densities. Foamed structure enables Xlite for a better thermal shock resistance. Xlite range can be safely used for service temperatures upto 1650°C for hot face linings.

Mortars (Insulating)

These mortars are used as jointing material for High Alumina Bricks and Insulation Bricks.

Some of the mortars are supplied as two-component system, where liquid binder is separately provided with powder material. In such a case, liquid component should be used only as per our recommendation. Where water is used as a liquid component, the amount of water used should be such that it results in trowelling consistency.
