Burning furnace,burnt body producing method, and burnt body

A method of manufacturing a sintered object, wherein the sintered object is formed by radiating microwaves to an object to be sintered, comprising the steps of:

• providing an inner shell (25) which can heat itself with microwaves and which defines a sintering chamber (16);
• disposing an object to be sintered (10) within the sintering chamber (16), the amount of heat generated with the microwaves per unit volume of the inner shell (25) being larger than the amount of heat generated per unit volume of the object to be sintered (10);
• and
• forming the sintered object by radiating microwaves to the object to be sintered (10) via the inner shell (25) using a microwave generator (12) in order to make the temperature of the inside surface of the inner shell (25) substantially the same as the surface temperature of the object to be sintered (10).

A sintered object obtained by a manufacturing method of a sintered object, wherein the sintered object is formed by radiating microwaves to an object to be sintered, the method comprising the steps of:

• providing an inner shell (25), which can heat itself with microwaves, the inner shell (25) defining a sintering chamber (16);
• disposing an object to be sintered (10) within the sintering chamber (16), the amount of heat generated with the microwaves per unit volume of the inner shell (25) being larger than the amount of heat generated per unit volume of the object to be sintered (10);
• and
• forming a sintered object by radiating microwaves to the object to be sintered (10) via the inner shell (25) using a microwave generator (12) in order to make the temperature of the inside surface of the inner shell (25) substantially the same as the surface temperature of the object to be sintered (10).

A continuous sintering furnace for sintering an object to be sintered (10) with microwaves comprising:

• an insulating wall (28) permeable to microwaves, wherein the insulating wall (28) defines a sintering chamber (16) and the object to be sintered (10) are disposed in the sintering chamber (16);
• a microwave generator (12) for radiating microwaves to the object to be sintered (10) via the insulating wall (28);
• and
• a feeding system for feeding the object to be sintered (10) into the sintering chamber (16),
• wherein the temperature within the sintering chamber (16) is changed in order to correspond to the sintering process of the object to be sintered (10) in the direction of feeding the object to be sintered (10).

A sintered object obtained by a manufacturing method of sintered object where the sintered object is formed by radiating microwaves to an object to be sintered (10), the method comprising the steps of:

• providing an insulating wall (28) permeable to microwaves, the insulating wall (28) defining a sintering chamber (16);
• disposing an object to be sintered (10) within the sintering chamber (16) by a feeding system;
• and
• forming the sintered object by radiating microwaves to the object to be sintered (10) fed into the sintering chamber (16) via the insulating wall (28) using a microwave generator (12) so that the temperature within the sintering chamber (16) is changed in order to correspond to the sintering process of the object to be sintered (10) in the feeding direction of the object to be sintered (10).
