Westmoreland Advanced Materials™ manufactures Premium Grade Ultra-Low Cement Castables using mullite as the alumina source. High quality, fully homogenized and fired mullite grains are purchased in the exact sizes needed to make an installation optimized castable. The mixes are formulated using Software Optimized Particle Size Distribution to obtain the best installation characteristics at the minimum water additions. The use of mullite grains instead of bauxite insures a mineralogical consistency not obtainable in less beneficiated raw materials. Mullite has the useful feature of slight expansion at higher temperatures, insuring that most linings will remain in a compressive state even as moisture is driven off during heat-up. Although not listed here, each of these products readily accepts our unique aluminum penetration resistant additive package for service in the aluminum industry. Call Westmoreland Advanced Materials™ for further information.
