Method of making a porous sintered body, a compound for making the porous sintered body, and the porous sintered body
A method of making a porous sintered body includes a formation step S102 where a sintering compound which contains a binder and a sinterable powder material is into a predetermined shape; a degreasing steps S103, S104 and S105 where the binder is removed from a formed body obtained in the formation step; and a sintering step S108 where a degreased body after the degreasing step is sintered into a sintered body. The binder contains a component which drains at a temperature higher than a draining temperature of the pore formation material drains. The pore formation material is drained in the degreasing step, with part of the binder remaining un-drained. The present invention enables to manufacture porous sintered bodies which are highly porous, and highly accurate in shape and dimensions. The present invention also enables to manufacture porous sintered bodies which offer functionalities not available before.
