ける必要が生ずる。Conventionally, when heat treating ferrite, etc., four setters with a thickness of about 4TnIrL were placed inside the bottom of a heat treatment container (for example, a sagger), and the material to be fired was placed on top of them.
It was heat-treated at ~1400°C. The material of the container used for this type of heat treatment is A12O. is 80% SiO. is 2
0% Al2O3-SiO. It is quality. The setter is Zr
The main components are ()O and CaO, each with 98%
and 2%. If we try to automate the entire process of heat treatment, it becomes necessary to mechanically tilt the container in the process of taking out the ferrite, capacitor, etc. after heat treatment.

層容器（以下単に複層容器という）及びその製造方法を
提供することにある。However, with conventional heat treatment containers, the setter would fall along with the ferrite, condenser, etc., which could cause the setter to break, or require a process to rearrange it when setting, hindering full automation. To solve this problem, there are methods to fix the setter with adhesive or to coat it with ZrO2 slurry instead of the setter, but if the setter is fixed with adhesive, Since the coefficient of thermal expansion is significantly different from that of the conventional Al2O3-SiO2 heat treatment container, it is usually 30 to 40.
Even though it could be used continuously, the setter cracked or peeled off after a few uses. In addition, firing is required three times: firing the heat treatment container, firing the setter, and firing after bonding, which results in poor thermal efficiency and is not economical. Also, Zr
Even when applying O2 quality slurry, the thickness of the ZrO2 layer is 1~
Only 2Tf$t was obtained, and the ZrO2 layer peeled off and large cracks occurred, making it impossible to withstand continuous use.
The purpose of the present invention is to eliminate the above-mentioned drawbacks and provide a multi-layer container for heat treatment of electronic industrial parts (hereinafter simply referred to as multi-layer container) suitable for automating the entire heat treatment process, and a method for manufacturing the same. It is in.

く歩留りか更に向上する。The multi-layer container according to the present invention has ZrO2 on top of Al2O3-SiO2 mixed powder mainly composed of Al2O3 and SiO2.
and ZrO2 mixed powder containing CaO as the main component was placed flat,
After integral press molding, the temperature is preferably 1300'C or higher. The 6A1203-SlO2 mixed powder obtained by firing at 1300-1600°C contains Al2O3.
It contains 75 to 95% of SiO2 and 5 to 25% of SiO2. ZrO2 mixed powder contains 91-97% ZrO2 and CaO
It contains 3 to 9%. The thickness of ZrO2 mixed powder is
Al. O3-SiO2 mixed powder.゜When the temperature is about 16T1$t, about 20% of about 4wrm is desirable, and after firing Z
The thickness of the rO2 layer 2 is the same as that of the ZrO2 layer 2. The thickness should be approximately 10 to 50% of the total thickness of the Al2O3-S1O2 main body 1. If the thickness of the ZrO2 mixed powder is thinner than this range, the ZrO2 mixed powder will be uneven and difficult to have a uniform thickness. As a result, the ZrO2 layer 2 contains SlO. The components move and become exposed, contaminating the object to be fired. On the contrary, Z
If the rO2 mixed layer is too thick, the coefficient of thermal expansion of the ZrO2 material is larger than that of the Al2O3-SiO2 material body 1, so deformation is too large during manufacturing, resulting in distortion of the bottom surface and poor yield. On the other hand, a mixed intermediate layer of Al2O5, SiO2, and zrO2 may be provided between the Al2O3-SIO2 layer and the ZrO2 layer (,,). CaO in the ZrO2 layer is ZrO
At the same time as suppressing the abnormal expansion of 2, the residual expansion rate is
3-Main body 1 of SiO2 material should be about 0.01 to 0.05% larger. As a result, when heat is applied to the multilayer container according to the present invention, due to the difference in thermal expansion of the ZrO2 layer 2, since the edge and bottom are in contact with the container body, the ZrO2 layer 2 stretches and moves upward. A lifting stress acts, and as shown in an exaggerated manner in FIG. 2, when there is no object to be fired, the bottom of the container body 1 tends to be lifted slightly upward by this stress. However, since the object to be fired is actually placed on the container, this stress is canceled out by the weight of the object to be fired, the weight of the bottom of the container body, etc., and the stress is balanced out as a whole. In this way, ZrO2
Since upward stress is applied to the heat treatment layer 2, it is possible to prevent the bottom from collapsing due to the weight of the object to be fired and the weight of the bottom of the container body 1, and the container has higher strength in hot conditions than conventional heat treatment containers. Furthermore, as shown in Fig. 3, Al2O3-S
When the ZrO2 slurry 3 is applied to the inside of the side wall 1a of the iO2 main body 1, even if the object to be fired comes into contact with the side wall, the material will not change in quality and the yield will be further improved.

複層容器は従来の容器と比較して少くとも倍近くの寿命
がある。このほかにも、本発明には次のような効果があ
る。The one in which the ZrO2 layer is integrally press-molded in a concave shape on the bottom of the O3-SiO2 body 1 can be used when the object to be fired is small.
This is preferable because the object to be fired does not come into contact with the N2O3-SiO2 side part. As described above, according to the present invention, it is not only easy to automate the entire heat treatment process, but also the strength of the heat treatment container is increased. In view of this, the multilayer container for heat treatment according to the present invention has a lifespan that is at least twice as long as that of conventional containers. In addition to this, the present invention has the following effects.
従来の熱処理用容器ではセッターとセッターの間に継ぎ
目があり、その上には被焼成物を乗せることができなか
つた。In conventional heat treatment containers, there is a seam between the setters, and the object to be fired cannot be placed on the seam.
しかし、、本発明による複層容器には継ぎ目がなく、積

なかつたが、本発明によると１回の焼成でフェライト特
性が得られる。However, the multilayer container according to the present invention has no seams, and the loading position is not limited. Therefore, the effective area becomes larger. Furthermore, since the internal volume of the multilayer container according to the present invention increases by the thickness of the setter, the loading capacity of objects to be fired increases. In addition, in conventional ferrite firing using a heat treatment container, ferrite characteristics could not be obtained unless the heat treatment container was fired several times, but according to the present invention, ferrite characteristics can be obtained with one firing.
