ABSTRACT:
Disclosed are methods for preparing carbon-containing materials resistant to alkali metal disruption, and compositions suitable for the preparation of carbon-containing materials resistant to alkali metal disruption. A composition in accordance with the invention comprises a mixture of (a) a binder phase having a viscosity of less than 10 Pascal seconds and a char yield in excess of 20% upon heating to a temperature of 800.degree.-1200.degree. C., and comprising at least one polymerizable resin and (b) particles of a solid material which is thermally stable at a temperature of 800.degree.-1200.degree. C., the particles having a granulometry wherein void spaces between the particles have a size of less than 20 .mu.m in diameter and the particles are coated with a layer of binder phase having a thickness of less than 2 .mu.m. When the composition is carbonized by heating to a temperature of 800.degree.-1200.degree. C., the composition forms a carbon-containing material resistant to alkali metal disruption.
