Abstract
The use of ceramic forming polymers to provide non-fugitive, high purity binders for densifying and sintering ceramic materials. The polymers have a backbone of silicon linked to carbon with primarily hydrogen side-groups. The advantages of the invention include dramatically strengthening the component during the pre-sintering heating.

Compositions for use as binders, densification enhancement aids, and sintering aids for ceramic powders, whiskers, and fibers comprising a silicon carbide forming polymer.
A composition for coating large particulates in order to bond the large particulates together into a component comprising a silicon carbide forming polymer as the vehicle to hold fine ceramic carbide powders in a liquid suspension.
A Method for bonding, densifying, and sintering ceramic powders, particles, whiskers, and fibers which comprises providing a silicon carbide forming polymer and applying the polymer to said powders, particles, whiskers, and fibers.
