| This paper contains the results of an
attempt made to use Indian sillimanite and
kyanite for the purpose of making insulating
bricks. In both cases fireclay has been used
as binding material. Saw dust has been
used in the case of sillimanite to impart
cellularity and in the case of kyanite
to act as a padding for its expansion.
Trials made were successful. Chemical
analyses, thermal conductivity, cold crushing
strength and other physical properties have
been mentioned. |
