, As, it is formed by adhering and closing a frit made of appropriate ingredients, but the compounding ingredients for kneading this frit are usually about 400 to 100% as well as adjusting the viscosity.
It is desirable that the adhesive be completely thermally decomposed during bonding at a high temperature of 0°C.

っている。However, methyl cellulose or ethyl cellulose is used as a conventional frit compounding agent, and a part of these becomes a thermal decomposition residue and has an adverse effect on the Pt wire. In other words, in methylcellulose and ethylcellulose, the ratio of oxygen to the combustible carbon and hydrogen is small, so the supply of oxygen from the atmosphere produces unburned carbon as a thermal decomposition residue, and the phosphate compounds contained in the frit,
Reacts with boron compounds, arsenic compounds, etc. to reduce oxides,
Generates P, B, As, etc. that easily react with metals,
These react with Pt to produce brittle intermetallic compounds, causing poor adhesion and leading to breakage of the Pt wire due to so-called corrosion. Furthermore, even if the wire does not break, the resistance value changes and the temperature indication becomes defective, making it practically unusable.

A Pt wire 1 with a small diameter of 17 μmφ is folded back and inserted into the two longitudinal holes of the Al2O3 pipe 2, and two wires are inserted at the end.
A Pt rhodium lead wire 3 with a diameter of 50 μm is connected,
The inside of the tube is filled with magnesia powder 4 and insulated. Further, frits 5 are bonded to both tube ends and sintered at about 1100°C.

。[0009] However, the nitrocellulose contained in this frit 5 contains a large amount of oxygen in the unit molecule, and the amount of oxygen is almost the same as that of combustible materials, so it has self-combustibility. , during sintering, almost no unburnt carbon is generated, so it is possible to prevent the generation of corrosive gases that are likely to be generated in a reducing atmosphere, and also to prevent the generation of intermetallic compounds, thereby preventing poor adhesion of the frit 5. Deterioration and disconnection of the Pt wire 1 can be prevented, and changes in the resistance value of the Pt wire 1 and temperature indication failures caused by the change can also be prevented.
