Title:
MANUFACTURE OF CONTROLLED DENSITY METAL BODY
Document Type and Number:
Japanese Patent JPS57177902
Kind Code:
A
Abstract:
Porous metal bodies of controlled density are produced by initially forming green bodies from a slurry comprised of at least one particulate metal compound capable of undergoing reduction to its free metal state wherein the ultimate density of the metal product is established through control of the precursor metal compound particle size and temperature conditions during reduction and sintering of the green bodies. In a preferred embodiment, the particulate metal compound includes a metal oxide in an aqueous slurry that is spray dried to form green oxide spheroids which are substantially simultaneously reduced and sintered to produce porous metal spheroids that are particularly useful as a carrier vehicle in electrostatographic developer compositions.
