DEFINITION

Classification: 264/669

Utilizing binder to add green strength to preform:

(under subclass 603) Process wherein a, usually organic, material is utilized to join particulate into a cohering self-sustaining preform capable of maintaining shape without disintegration.

(1) Note. During sintering, the shape of this temporary preform (i.e., green body) is retained due to particle-to- particle surface bonding, while organic binder is simultaneously removed by volatilization or decomposition.
