Dakota Formation Refractory Clays and Silts in Kansas

Abstract

Routine ceramic testing (supplemented by chemical analysis and hot load testing) of samples of refractory clay and silt from the Dakota Formation from 25 locations in Kansas showed that some of the clays can be formed into a good grade of semi-silica refractory brick. The brick exhibit excellent volume stability and hot-load-carrying characteristics at temperatures as high as 2500° F.
