Abstract
Provided is a method for producing a metal solid, the method being capable of easily producing a metal solid. A method for producing a metal solid, the method comprising covering at least a portion of the periphery of a metal powder with a high-melting-point material having a melting point higher than the melting point of the metal powder; and irradiating the metal powder, at least a portion of the periphery of which is covered with the high-melting-point material, with microwaves to heat the metal powder, thereby sintering or melt-solidifying the metal powder.
Claims21
A method for producing a metal solid, the method comprising:
- covering at least a portion of a periphery of a metal powder with a high-melting-point material having a melting point higher than the melting point of the metal powder;
- and
- irradiating the metal powder, at least a portion of the periphery of which is covered with the high-melting-point material, with microwaves to heat the metal powder, thereby sintering or melt-solidifying the metal powder,
- wherein in the portion of the metal powder covered with the high-melting-point material, the metal powder and the high-melting-point material are in contact with each other, and the high-melting-point material includes a mixture of:
- an insulation material that has a lower degree of absorption of the microwaves than the metal powder, and
- an absorbent material that absorbs the microwaves in a temperature zone at least a portion of which is lower than a temperature zone in which the metal powder absorbs the microwaves.
