THERMOPLASTIC MOLDING OF SINTERABLE SILICON CARBIDE Abstract of the Disclosure A thermoplastically moldable ceramic composition comprised of from about 40% to about 60% by volume of a sinterable silicon carbide powder and a binder comprised of an organic acid and a copolymer of ethylene and from greater than about 12 weight % to about 33 weight % vinyl acetate, said organic acid having a melting point ranging from about 44°C to about 88°C and ranging from greater than about 18% by weight up to about 45% by weight of the binder. The ceramic composition is thermoplastically molded into a body which is baked to remove the binder and then sintered.
