Abstract
Studies were carried out for development of machinable ceramics
from indigenous mica. A composition containing mica, 8-12% glass
and sintering aids up to 10% resulted in dense and impervious bodies
on heat treatment up to 1100°C. XRD patterns and SEM fractographs
were used to study the phase changes and microstructure of the
sintered compacts. Properties like degassing rate and electrical
breakdown strength were measured. The samples were machinable
and showed no chipping during machining.
