Definitions
- the present invention relates to a jig for firing electronic components such as setters, shelves, and saggers used for firing electronic components such as dielectrics, multilayer capacitors, ceramic capacitors, piezoelectric elements, and thermistors.
- a jig for firing electronic components may not react with ceramic electronic components to be fired.
- an electronic component work such as a dielectric material comes into contact with and reacts with a firing jig, there are problems such as fusing or a change in the composition of the work, resulting in deterioration of characteristics.
- an alumina-based material an alumina-lite-based material, an alumina-magnesia-based spinel material, an alumina-lite-colite-based material, or a combination thereof is used.
- zirconia zirconium oxide, ZrO
- Zircoure has low reactivity with the base material, but due to the large difference in thermal expansion coefficient from the base material, problems such as cracking or peeling of the jig coating under the usage environment where repeated thermal cycles occur. There is. Also, when the jig is used repeatedly, if the particles contained in the surface zirconia surface layer fall off and the particles have a low abrasion resistance and a low abrasion resistance, fine particles are mixed into the electronic components, causing a serious problem. Furthermore, zircon undergoes a phase change from monoclinic to tetragonal at around 1100 ° C.
- a method of forming a zirconia surface layer (or a zirconia film) on the surface of a base material of an electronic component firing jig there are an application method, a dip coating method, a spray coating method and the like. These methods are relatively inexpensive and are suitable for industrial production, but the resistance of the formed zirconia surface layer is Abrasion resistance: abrasion resistance is not enough! , In some cases.
- the surface layer of the zirconia may peel off the base material or may be degranulated.
- the zirconia surface layer is formed using coarse particles, the zirconia surface layer does not become dense, and a large number of pores are formed so that the difference in thermal expansion from the base material is reduced.
- the adhesion between the zirconia film and the base material is poor, and the sinterability of the film is reduced, which may cause peeling.

The liquid phase 6 gradually penetrates through the zirconia surface layer in the direction of the substrate (FIG. 1 (B)).
- Substrate 1 usually contains a silica component, and when this liquid phase penetrates into substrate 1, the silica in substrate 1 is sucked up into the surface layer of zirconia (Fig. 1 (C)).

- the content of force lucia was about 3% by weight at maximum, but in the first invention, the force lucia content is 4 to 15% by weight. If the amount is less than 4% by weight, the improvement of the long-term peeling resistance by addition is insufficient, and if the amount exceeds 15% by weight, further improvement of the long-term peeling resistance cannot be expected.
- the long-term peeling resistance increases as the content increases, but the short-term peeling, warping, and shedding (ragging) content is 4 to 15% by weight. No substantial difference is seen within the amount range.

- an electronic component firing jig having excellent long-term exfoliation resistance and exfoliation resistance can be obtained, and have reached the second invention.
- the gap is more likely to be closed by the intermediate grain zirconia, so that the porosity is further reduced. Due to this decrease in porosity, peeling due to thermal cycling is slightly more likely to occur, but the zirconia surface layer becomes denser and suppresses penetration of the liquid phase, greatly reducing the possibility of peeling due to reaction, and overall peeling resistance Sex is improved.

If it exceeds sinterability, the sinterability decreases. If the average particle size of the fine zirconia is less than 0.1 ⁇ m, the effect of improving the adhesion between the coarse zirconia and the base material becomes too small due to a too large difference in particle size between the coarse zirconia and If it exceeds, the effect of the addition of fine zirconium is reduced by approaching the intermediate zirconia.

Only the use under the condition of not less than 3% by weight and not less than 3% by weight is implied, and there is no known effect proved by experimental data. In other words, it is unclear whether or not the performance of the jig for firing electronic components is improved by actually adding tantalum to the partially fused binder.
