HIGH ALUMINA DENSE REFRACTORY SHAPES
Kyanex Shapes are made from Natural Sillimanite. Natural Sillimanite is highly volume stable at elevated temperatures. Besides, it has also very low impurities such as Iron Oxide, Titania and Alkalies. Sillimanite has a very good resistance to thermal shocks. Sillimanite make "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.
The best choice for Burner Blocks, Refractory Quarls, and Burner Throat Tiles 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 Sillimanite are ideally suited for the above application areas.
Also our, Sillimanite Element Holding Bricks offer low iron contamination in industry application.
