（産業上の利用分野）
本発明はセラミックス等の粉末焼結品の製造方法および
着色方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing and a method for coloring powder sintered products such as ceramics.
（従来の技術）
種々の材料の粉末を成形し、それを構成する材質の融点
以下の温度で加熱して強固な結合をつくりだし、部品と

金属粉末を利用したものは既に粉末冶金として完全に実
用化領域にある。(Prior art) Attempts have been made for some time to form powders of various materials and heat them at temperatures below the melting point of the materials that make up the material to create strong bonds and use them as parts. The material used is already in the realm of practical application as powder metallurgy.
また、この方法は、金属のみならずセラミ７クスの樺に
高融点で、溶解や鋳造では製造困難な材料においては欠
かせない工法の１つである。In addition, this method is one of the indispensable methods not only for metals but also for ceramics such as birch, which has a high melting point and is difficult to manufacture by melting or casting.
このようなセラミックスなどの粉末焼結品は高機能化が
進み、また、材質に関しても単一成分から複数成分系へ
と進んできている。Powder sintered products such as ceramics are becoming more highly functional, and materials are also progressing from single-component to multi-component systems.
（発甥が解決しようとする課題）

コストは多大なものとなり、かつ成分的にも固溶量の制
限をうけた従来の溶製材の域を出ない。(The problem that Hatsunebe is trying to solve) However, the resulting powder is not a mixture of powders of each single component of the sintered crystal component, but a powder of an alloy component in which they are dissolved as a solid solution. As a result, the cost of producing the powder is enormous, and it is no more than conventional melted lumber, which is limited in terms of the amount of solid solution.
また、焼結晶成分の各構成成分粉末を混合した場合、機
械的混合によるため、均一化が難しく、混合ムラが発生
して焼結晶に悪影響を及ぼすという課題があった。Furthermore, when the constituent powders of the baked crystal component are mixed, it is difficult to achieve uniformity due to mechanical mixing, and uneven mixing occurs, which adversely affects the baked crystal.
本発明は上記の課題を解決し、その目的とするところは
、均質な粉末焼結品を容易に得ることができる粉末焼結
品の製造方法および着色方法を提供することにある。The present invention solves the above problems, and its purpose is to provide a method for producing a sintered powder product and a method for coloring the product by which a homogeneous sintered powder product can be easily obtained.
（！ＩＮを解決するための手段）
本発明では、焼結可能な粉末と熱可塑性樹脂等を主体と

目的を達成している。(Means for solving !IN) In the present invention, a sinterable powder and a binder mainly made of thermoplastic resin are kneaded, molded by injection molding or the like, and then the binder is removed by heating or other means. The above objective is achieved by adding metal ions after removing most or all of the powder, followed by sintering to produce a powder sintered product.
また、金属イオン添加工程として、脱脂品を金属イオン
を含んだ溶液中に浸漬もしくは含浸するようにしたり、
この場合、真空中でこれを行うようにしている。In addition, as a metal ion addition step, the degreased product is immersed or impregnated in a solution containing metal ions,
In this case, this is done in a vacuum.
また、上記において、粉末にアルミナ、ジルコニア等の
セラミックス粉末を用い、かつ溶液にはクロム、コバル

している。Further, in the above, ceramic powder such as alumina or zirconia is used as the powder, and a solution containing metal ions such as chromium or cobalt is used as the solution for coloring.
（作用）
上述のように本発明では、成形品を脱脂した後に均一に
生じた空孔に金属イオンを注入・吸着するようにしたの
で、金属イオンを均一化させることができ、かつ均一に
発色させることができるようにしている。(Function) As described above, in the present invention, metal ions are injected and adsorbed into the pores uniformly generated after degreasing the molded product, so that the metal ions can be uniformized and the color can be uniformly developed. I'm trying to be able to do that.
（実施例） 以下、図面に沿って本発明の一実施例を説明する。(Example) An embodiment of the present invention will be described below with reference to the drawings.

and an organic binder such as polyvinyl acetate as binder 2 were kneaded in a pressurized niegu.
この混練された材料３を射出成形工程にて成形した。This kneaded material 3 was molded in an injection molding process.
この成形品４は脱脂工程において、例えば３５０℃まで
２４時間かけて昇温し、有機結合剤を除去した。In the degreasing step, the molded article 4 was heated to, for example, 350° C. over 24 hours to remove the organic binder.
このようにして得られた脱脂品５は内部に有機結合剤が
存在していた部分が空孔として存在し、非常にポーラス
である。The degreased product 5 thus obtained is extremely porous, with the portions where the organic binder was present existing as pores.
この脱脂品５を、第２図（ロ）に示す如く、例えば（：

As shown in FIG. 2(a), the degreased product 5 is immersed in an aqueous solution 6 in which oClg is dissolved, and more preferably, this immersion is performed in a vacuum. You may also let them do so.
そして、このＣｏイオンを含んだ脱脂品５を乾燥させて

Moreover, it is possible to use not only an aqueous solution but also an alcohol solution. In other words, it is sufficient that the required metal exists in the solution in the form of ions.

For example, by accelerating Cr ions at 1.5 MeV on a degreased product made of AIgOs,
When the 17 ions/cm" injected material was sintered, uniform color development was observed.
