ABSTRACT:
An inorganic composition useful as material for Lehr rolls at temperatures above 500.degree.C consists essentially of 15-45% chrysotile asbestos, 40-75% talc component and 2-35% inorganic binder. The composition is also used in manufacturing millboard by forming a water slurry of said composition and transferring said slurry to a rotating screen cylinder, then to a moving belt and then to a rotating drum upon which layers of said slurry accumulate upon each other and are thereafter slit, dried and formed into a flat sheet.
