Abstract
The present invention provides a nano-precision sintering systemfor sintering a nano-sized powder of a material in the pulse energization and pressure sintering process to obtain a highly purified sintered compact having a nano-sized grain structure, said nano-precision sintering systemcomprising: at least one pre-process chamberdefined by at least one sealed housinghaving at least one glove and designed to be controlled into a predetermined atmosphere; a sintering process chamberdefined by a sealed housinghaving at least one glove and designed to be controlled into a predetermined atmosphere; a shut-off systemdisposed in a passage providing communication between the pre-process chamber and the sintering process chamber so as to block the communication between the two chambers selectively while keeping it in an air tight condition; and a pulse energization and pressure sintering machinehaving a vacuum chamber 'C' allowing for the sintering process to be carried out under a vacuum atmosphere, wherein the vacuum chamber is disposed in the sintering process chamber such that the former can be isolated from the latter.
