Document Type and Number:
Japanese Patent JP2019137578
Kind Code:
A
Abstract:
To provide a degreasing apparatus for a ceramic compact, a firing apparatus for the same, a degreasing method for the same, and a production method for a ceramic body, capable of performing degreasing efficiently by enhancing the flow rate of gas passing around the ceramic compact.SOLUTION: A degreasing apparatus 1 includes: a lower gas-supplying port 25 provided on a lower side thereof; and a gas-discharging port 21 and an upper gas-supplying port 23 provided on an upper side of the lower gas-supplying port 25. Accordingly, a degreasing gas supplied from the lower gas-supplying port 25 is discharged from the gas-discharging port 21, and a rectifying gas is supplied from the upper gas-supplying port 23 into the inside of the degreasing apparatus 1. That is, a portion that functions like an air curtain is formed by the rectifying gas supplied from the upper gas-supplying port 23. Therefore, the degreasing gas supplied from the lower gas-supplying port 25 flows around the ceramic compact 3, thereby enhancing the flow rate of gas.SELECTED DRAWING: Figure 2
