- the binder is removed by pre-baking (removal of binder) by holding the pressed body at 60 O in the atmosphere for 15 minutes.
- the calcined product (13.5mmX6.8mmX2.7mm) was obtained.
- the calcined body was placed in a rectangular cylindrical Kovar metal frame with a height of 5 mm and a size of 14 mm x 7 mm, and the upper and lower surfaces were 6 mm thick and a 13.5 mm x 6.5 mm carbon plate. Two pieces were sandwiched and fixed to the metal frame.
- the coloring property, the joining strength, the foaming property, the carbon adhering property, the gas releasing property, and the molding workability were evaluated as follows.
- Colorability The surface of the calcined body was visually observed, and those without coloring or discoloration were rated good, and those with slight coloring or discoloration were rated poor. This coloring or discoloration is caused by the lack of binder removal, and it is considered that the effect of the binder removal in the calcined body cannot be removed by the main firing.
- Bonding strength The Kovar metal frame of the bonded body was fixed with a jig, and a force of 147 N was applied to the glass molded body of the bonded body. A glass molded body that did not peel from the Kovar metal frame was rated good, and a peeled glass molded body was rated poor.
- Foaming property The bonded body was left standing for 1 hour under a reduced pressure atmosphere with a pressure of 3 OTorr (4000 Pa) and a temperature of 800, and was taken out. Those that were not acceptable were rated good, and those that were recognized were rated poor.
- Carbon adhesion When the carbon plate is removed after cooling after completion of the main firing, the carbon plate is not fused to the glass molded body and can be easily removed, and there is no carbon bond on the surface of the glass molded body. Good, otherwise bad.
- Outgassing The joined body was heated from room temperature to 800, and the type and amount of gas generated in the process were examined using a gas mass spectrometer. A case where remarkable gas release was observed was regarded as bad, and a case where it was not noticeable was regarded as good.
- Molding workability If granulated powder adheres to the inner surface of the mold during the production of the pressed body, problems such as a decrease in the dimensional accuracy of the pressed body and a decrease in the strength of the pressed body will occur. In order to prevent this granulation powder from sticking, the inside of the mold is cleaned to remove deposits on the mold, but the frequency should be once or less every 200 dry presses. Is preferred. The cleaning frequency was good if the cleaning frequency was less than or equal to once every 2000 times, and poor if it was not.
- Example J 1 Example 2 Example 3 Example 4 Example 5
- the sealing part or joining part of glass, metal, ceramics, etc. is not colored or discolored, its strength is high, there is no bleeding of glass, No or little gas is released, and there is no sticking to the carbon jig used at the time of sealing or joining, so that a sealing material having good press body molding workability can be obtained.
- the method of bonding and sealing the pre-fired press body by firing and bonding or sealing it depends on the shape or size of the press body. In many cases, it had to be contained, and there was a problem of insufficient binder removal. If the binder removal is insufficient, carbon remains in the fired body that has been finally fired, and the fired body is colored. And other problems may occur.
