（産業上の利用分野）
本発明は、再使用可能な陶磁器全面の釉薬焼付けにおけ
る円錐状受は台に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a conical receiver for glazing the entire surface of reusable ceramics.
（従来の技術〉
一般に陶磁器は、原料を混合・混練して坏土とし、これ
を所定の形状に成形し、乾燥後素焼きして、次いで表面
に釉薬を塗布し本焼きすることにより製造される。(Conventional technology) Generally, ceramics are manufactured by mixing and kneading raw materials to make clay, molding it into a predetermined shape, drying and unglazing it, then applying glaze to the surface and firing it. .
このうち釉薬の焼付けは、通常本焼き時の台と接触する
部分を除いて釉薬を塗布して行う、しかし、一部高級品
等は、全面に釉薬の塗布を行う場合があり、従来この場
合には、アルミナからなる頂部形状が１Ｒ程度の円錐状
の受は台を使用し、陶磁器の底面を３点で保持して、釉
薬を塗布し焼付けを行っていた。Of these, glaze baking is usually done by applying glaze to the entire surface, except for the parts that come in contact with the table during final firing.However, for some high-end products, glaze may be applied to the entire surface, and conventionally this is not the case. A conical support made of alumina with a top shape of about 1R was used to hold the bottom of the ceramic piece at three points, and the glaze was applied and fired.
（発明が解決しようとする問題点）
しかしながら、従来のアルミナからなる円錐状受は台で
は、−回の使用で、頂部が破損するが摩耗してしまい、
再使用できないという問題があった。また、アルミナは
釉薬に塗れやすく、保持した部分が欠点となりやすいと
いう問題もあった。(Problems to be Solved by the Invention) However, the conventional conical receiver made of alumina wears out after being used for - times, although the top part is damaged.
There was a problem that it could not be reused. There was also the problem that alumina was easily coated with glaze, and the retained portions were likely to become defects.
本発明は、このような問題を解決するためになされたも
ので、頂部の破損や摩耗が少なく、再使用可能な釉薬焼
付けにおける円錐状受は台を提供することを目的とする
。The present invention has been made to solve these problems, and aims to provide a reusable conical receiver for glaze baking with less damage or wear on the top.
［発明の構成コ
（問題点を解決するための手段）
すなわち本発明は、釉薬の全面塗布における焼付は時の
円錐状受は台を、実質的に窒化ケイ素により形成したこ
とを特徴としている。[Structure of the Invention (Means for Solving the Problems)] That is, the present invention is characterized in that the conical receiver base used for baking in the entire surface application of glaze is formed substantially of silicon nitride.
本発明の釉薬焼付けにおける円錐状受は台は、窒化ケイ
素からなる頂部形状が０．５〜１Ｒの円錐状のものであ
る。The conical receiver in the glaze baking of the present invention is made of silicon nitride and has a conical top shape of 0.5 to 1R.
また、これを得る方法としては、緻密質で機械強度に優
れたものが得られるホットプレス法が好ましく、次いで
機械加工により所定の形状にすることにより得られる。In addition, as a method for obtaining this, a hot pressing method is preferred since it produces a dense product with excellent mechanical strength, and then it is obtained by machining it into a predetermined shape.
（作用）

に優れているため、焼付は時の温度が１２００〜１４０
０℃と高温になるが、破損や亀裂等の欠点を生じること
もない。(Function) In the present invention, silicon nitride has a large hardness and n16
It has excellent abrasion resistance, so even if the top shape is a sharp edge of about 0.5R, the top sometimes gets damaged due to seizure, and the top R is difficult to increase due to skewer wear, so it can be reused. Also, since it is difficult to apply the glaze, it is possible to prevent the holding part from becoming a drawback. Furthermore, it has excellent thermal shock resistance, so the baking temperature is 1200-140°C.
Although it reaches a high temperature of 0°C, it does not cause defects such as damage or cracks.
（実施例） 次に本発明の実施例について説明する。(Example) Next, examples of the present invention will be described.

５Ｒ５底部外径２５１１１１、高さ１５ｎｉの円錐状受
は台を形成した。Example First, 5 parts by weight of yttrium oxide and 3 parts by weight of aluminum oxide were added as sintering aids to 100 parts by weight of silicon nitride (Si3N4) powder with an average particle size of 2 to 3 μm, and after thorough mixing, the 1 paraffin as a binder
0 part by weight was added, hot-pressed under conditions of a pressure of 500 to 1000 kg/d and a temperature of 1750 to 1800°C, and then machined to form the top shape 0, as shown in Figure 1.
A conical receiver with a 5R5 bottom outer diameter of 251111 and a height of 15 ni formed a pedestal.

に耐えうる状態であった。As a result, although the top of the conventional glaze receiver made of alumina was damaged after 50 tests, the top of the conical receiver made of silicon nitride according to the present invention was damaged even after 50 tests. No damage was observed, and the shape was 0.5R, meaning it was still usable.
