［従来の技術］
ファインセラミックスは耐熱性、耐熱衝撃性、耐食性等
に優れ、また機械的にも化学的にも安定な物性を有する
ことから、今日、電子、機械部品をはじめとして、多方
面での利用が注目されている。しかし、セラミックスは
一般に機械加工性に乏しく、成形や組立に支障を来たし
て適用が妨げられることが多い。このため、その接着技
術を確立することが重要な課題とされる。[Conventional technology] Fine ceramics have excellent heat resistance, thermal shock resistance, corrosion resistance, etc., and have mechanically and chemically stable physical properties, so today they are used in many fields including electronic and mechanical parts. The use of is attracting attention. However, ceramics generally have poor machinability, which often causes problems in molding and assembly, thus hindering their application. Therefore, establishing the adhesive technology is an important issue.
従来、セラミックスとセラミックスあるいはセラミック
スと金属とを接着する方法の主なものとして、ホットプ
レス法や高融点金属を用いるろう付は法などが知られて
いる。Conventionally, hot pressing methods and brazing methods using high-melting point metals are known as main methods for bonding ceramics to ceramics or ceramics to metals.
前者は、高温高圧下でセラミックス界面の拡散接合を行
うものであり、界面に基利粉末を挟んで接着する場合も
ある。The former method involves diffusion bonding of the ceramic interface under high temperature and high pressure, and may also include bonding by sandwiching base material powder at the interface.

Ａｇ−Ｃｕ合金やＡｇ−Ｐｂ合金等を用いて接着する方
法（特開昭５８−１６１９７８号公報）である。On the other hand, for the latter, fine powder such as Mo, Mo-Mn, etc. is applied to ceramics, metallized at a temperature of 1-300 to 1700°C in humidified hydrogen or humidified forming gas, and then nickel plated on top. This is followed by bonding using an Ag-Cu alloy, Ag-Pb alloy, or the like as a brazing material (Japanese Unexamined Patent Publication No. 161978/1983).
［発明が解決しようとする問題点コ
しかしながら、上記の接着方法には次のような問題があ

具合がある。[Problems to be Solved by the Invention] However, the above adhesive method has the following problems. In other words, although it is known that the hot press method can produce a bonded body with high strength, it tends to cause creep deformation of ceramics etc. during bonding, resulting in molding defects in the bonded area and base material, and requires large auxiliary equipment such as press equipment. There is a problem that occurs.
また、高融点金属によるろう骨法では、強固な接合体を
得るためにはやはり相当高い温度に加熱する必要がある
ことに加え、貴金属を主成分とするろう材を多量に使用
することと、接着工程が複雑になることにより、コスト
高を招来する不利がある。In addition, in the brazing bone method using high-melting point metals, it is necessary to heat the joint to a considerably high temperature in order to obtain a strong joint, and it is also necessary to use a large amount of brazing filler metal whose main component is noble metal, This has the disadvantage of increasing costs due to the complicated process.
本発明は、かかる問題点に鑑み、セラミックス同士ある
いはセラミックスと金属とを簡単で安価に接着すること
ができるセラミックス接着剤を新たに提供するものであ
る。In view of these problems, the present invention provides a new ceramic adhesive that can easily and inexpensively bond ceramics together or ceramics and metals.
［問題点を解決するだめの手段及びその作用］本発明の
セラミックス接着剤は、基本的には、ホウ素酸化物（８

も差し支えない。[Means for solving the problems and their effects] The ceramic adhesive of the present invention basically contains boron oxide (8
203) is mainly composed of manganese oxide and cobalt oxide, and depending on the adhesion mode and conditions, other oxide components described below may be added and used. It is preferable that the manganese oxide takes the form of MnO and the cobalt oxide takes the form of Coo, but other oxide forms may be used.
接着剤成分のうち、Ｂ２Ｏ３とＭｎＯは被接合物間の接

起こし接着力を強化する。Ｂ２Ｏ３とＭｎＯとの混合比
は、広い範囲で選ぶことが可能であるが、接着剤層の熱
膨張率が被接着物のそれと近似するように調整される。Among the adhesive components, B2O3 and MnO form the skeleton of the overall structure in the adhesive layer between the objects to be joined. In particular, MnO diffuses into the ceramic or metal to be bonded and strengthens the bonding force. Further, when bonding ceramics and iron-based alloys, CoO causes electrochemical erosion with Fe (Fe+Co2+→Co+Fe2+) to strengthen the adhesive force. The mixing ratio of B2O3 and MnO can be selected within a wide range, but it is adjusted so that the coefficient of thermal expansion of the adhesive layer approximates that of the object to be adhered.
被接着物が異なる場合は、両者の中間的な熱膨張率を示
すように調整される。また、ＣｏＯは１０重量％以下で
足り、この範囲の含有量で十分効果を発現する。If the objects to be adhered are different, the thermal expansion coefficient is adjusted to be intermediate between the two. Further, CoO is sufficient at 10% by weight or less, and a content within this range can sufficiently exhibit the effect.
以上に述べた主成分の他に、本発明の接着剤では、必要
に応じて更に以下の酸化物を添加して用いることができ

めるのに効果があり、前記主成分のみの配合では接着剤
強度が不足する場合に、添加が有効となる。なお、その
含有量は５〜１５重量％である。Aluminum oxide (Ag2O3) is effective in increasing the strength of the adhesive, and its addition is effective when the strength of the adhesive is insufficient when only the main component is blended. In addition, its content is 5 to 15% by weight.
また、ＩＡ族元素の酸化物、例えばに２０． Ｎａ２Ｏ
等は、接着剤の熱膨張率の調整に有効な成分であって、
前記主成分比（Ｂ２０３ ／Ｍｎ０）を変えても所望の

わち、これらの酸化物の一種又は二種以上を含むことで
、より広範囲なセラミックス等の接着に利用できる。Also, oxides of Group IA elements, such as 20. Na2O
etc. are effective ingredients for adjusting the coefficient of thermal expansion of the adhesive,
Addition becomes effective when a desired coefficient of thermal expansion can be obtained even if the ratio of the main components (B203/Mn0) is changed. That is, by containing one or more of these oxides, it can be used for bonding a wider range of ceramics and the like.
さらに、接着するセラミックスが特にジルコニアである
場合には、その安定化剤（Ｙ２Ｏ２等）を含有させるの
が好適となる。ジルコニアセラミックスでは、その相転
移を防ぐため安定化剤を含有しているが、接着時乃至接

接着剤中に拡散して欠乏することがある。かかる安定化
剤の拡散を抑え、強度劣化を防止するため、接着剤には
０．１〜１０重量％の安定化剤を予め含ませるのが良い
。Furthermore, especially when the ceramic to be bonded is zirconia, it is preferable to include a stabilizer thereof (such as Y2O2). Zirconia ceramics contains a stabilizer to prevent phase transition, but depending on the temperature during bonding or during use, the stabilizer in zirconia may diffuse into the adhesive and become depleted. . In order to suppress the diffusion of such a stabilizer and prevent strength deterioration, it is preferable that the adhesive contains 0.1 to 10% by weight of a stabilizer in advance.

は真空に調整すると良い。When bonding ceramics together or ceramics and metals (mainly iron-based alloys) using the adhesive of the present invention, it can be applied to the surface of one base material either in powder form or by using an organic binder. After applying the adhesive, the other base material may be placed on top of the adhesive and heated to -42° above the melting point of the adhesive (approximately 800 to 1,200°C). At this time, slight pressure may be applied to improve the adhesion between the object and the adhesive. Also,
The atmosphere during bonding is preferably adjusted to a reducing or weakly reducing gas or vacuum.
