METHOD OF MAKING A POROUS SINTERED BODY, A COMPOUND FOR MAKING THE POROUS SINTERED BODY, AND THE POROUS SINTERED BODY
A thermal formation sintering compound containing a binder, a sinterable powder material and a pore formation material, for formation into a predetermined shape in a thermal formation step, removal of the binder in a degreasing step, and sintering of the powder material in a sintering step is provided. The binder contains a low-temperature draining component which melts in the thermal formation step, begins draining at a temperature lower than a draining temperature of the pore formation material, and drains at a temperature lower than a temperature at which the pore formation material drains; and a high-temperature draining component which melts in the thermal formation step, begins draining after the pore formation material begins draining, and drains at a temperature higher than does the pore formation material.
