〔産業上の利用分野〕
本発明は、高温機械部品、特にガスタービン部品のラジ

、かつ高温で高い強度を要求される部品の、炭化ケイ素

射出成形法により製造するのに適する組成物に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to high-temperature mechanical parts, particularly gas turbine parts such as radial rotors and axial rotors, which have complex shapes and require high strength at high temperatures. The present invention relates to a raw material powder made of silicon carbide for parts, and in particular to a composition suitable for manufacturing the above-mentioned parts by injection molding.

うだ複雑な形状を有する部品を製造することはできない
。In order to sinter silicon carbide at normal pressure, 2. Usually, a sintering aid is added to fine particles with an average particle size (lL5 μm or less), and the molded body is fired in an inert atmosphere.In this case, molding ,
If a forming method such as hydrostatic pressing 1 is employed, a dense (51V or more) and high-strength sintered body can be obtained. However, it is not possible to manufacture parts with complicated shapes such as radial rotors and axial rotors of gas turbine parts.
このような複雑形状の部品の成形には射出成形が最も適
するが、平均粒径が１５μｍ以下の炭化ケイ素微粒子を
原料とした場合は原料の比表面積が大きくなるため、有
機結合剤との混練時に、混線トルク値が高くなり、均一
な混合が困難となる。Injection molding is most suitable for molding parts with such complex shapes, but when silicon carbide fine particles with an average particle size of 15 μm or less are used as a raw material, the specific surface area of the raw material becomes large, so it is difficult to mold when kneading with an organic binder. , the crosstalk torque value becomes high and uniform mixing becomes difficult.
また成形時にも混線物の流動性が悪いため、射出成形体
に密度むらやつまり不良による欠陥が生じやすく、脱脂
、焼成後に割れとなって現われる。Also, during molding, the fluidity of the mixed material is poor, so defects due to uneven density or clogging are likely to occur in the injection molded product, which appear as cracks after degreasing and firing.
すなわち、射出成形性が劣る。That is, injection moldability is poor.
一方、射出成形性に優れた平均粒径が（１６μｍ以上の
粗粒子を用いること圧より成形体に欠陥は生じないが、
焼結体の密度は低下しく五〇５ｆ／ｄ以下）９強度もこ
れだ伴なって低下してしまい。On the other hand, using coarse particles with an average particle size of 16 μm or more, which has excellent injection moldability, does not cause defects in the molded product due to pressure, but
The density of the sintered body decreases (less than 505 f/d), and the strength also decreases accordingly.
焼結性および焼結体特性の低下という新たな問題が生じ
てしまう。A new problem arises: deterioration of sinterability and properties of the sintered body.
このように、射出成形性と焼結体特性の両方に優れた炭
化ケイ素粉末が要望されているが、これまでに得られて
いなかった。As described above, there is a demand for a silicon carbide powder that is excellent in both injection moldability and sintered body properties, but so far none has been available.
本発明は、上記従来技術の問題点に鑑みなされたもので
あり、成形性と焼結体特性が共に良好な炭化ケイ素組成
物を提供することを目的とするものである。The present invention was made in view of the problems of the prior art described above, and it is an object of the present invention to provide a silicon carbide composition that has good moldability and sintered body properties.
本発明の炭化ケイ素組成物は、平均粒径（Ｌ５μｍ以下
の炭化ケイ素粉末２０〜８０重量％と。The silicon carbide composition of the present invention contains 20 to 80% by weight of silicon carbide powder having an average particle size (L5 μm or less).
残部が平均粒径ＣＬ６〜５μｍの炭化ケイ素粉末とから
収ることを特徴とするものでろる。The remainder is characterized by being comprised of silicon carbide powder with an average particle size CL of 6 to 5 μm.
本発明において、平均粒径が１５μｍ以下の微粒の炭化
ケイ素（８ｉＣ）粉末は、８ｉ０．還元法等で＠−成す
ることができる。該微粒の炭化ケイ素粉末の平均粒径を
ＣＬ５μｍ以下としたのは、平均粒径が１５μｍを超え
る粒子では緻密な焼結体が得られないからである。In the present invention, fine silicon carbide (8iC) powder with an average particle size of 15 μm or less is 8i0. It can be achieved by reduction method etc. The reason why the average particle size of the fine silicon carbide powder is set to CL5 μm or less is that a dense sintered body cannot be obtained with particles having an average particle size exceeding 15 μm.
また、平均粒径が［Ｌ６〜５μｍの粗粒の炭化ケイ素粉
末は、アチェソン法等で合成することができる。該粗粒
の炭化ケイ素粉末の平均粒径を０６〜５μｍとしたのは
、平均粒径［ｌＬ６μｍ未満の粉末を用いたのでは粗粒
としての効果がなく欠陥のない成形体が得られないから
であり、また、平均粒径５μｍを超える粗大粒を用いた
のでは微粒子と混合しても、緻密な焼結体が得られない
からである。Further, coarse silicon carbide powder having an average particle size of [L6 to 5 μm] can be synthesized by the Acheson method or the like. The reason why the average particle size of the coarse silicon carbide powder is set to 06 to 5 μm is because if a powder with an average particle size of less than 6 μm is used, it will not be effective as a coarse particle and a defect-free molded body will not be obtained. Moreover, if coarse particles with an average particle size exceeding 5 μm are used, a dense sintered body cannot be obtained even if mixed with fine particles.
また、上記炭化ケイ素の形態としては、微粒のもの、粗
粒のものともアルファー（ａ）、ベータ＜ｐ）等いずれ
のものでもよい。Further, the form of the silicon carbide may be fine particles, coarse particles, alpha (a), beta<p), or the like.
微粒の炭化ケイ素粉末（これを人とする。）と粗粒の炭
化ケイ素粉末（これをＢとする）との配合割合は１重量
比でＡ／Ｂ−２／８〜８／２の割合とする必要がある。The blending ratio of fine silicon carbide powder (this is referred to as human) and coarse silicon carbide powder (this is referred to as B) is a ratio of A/B-2/8 to 8/2 by weight. There is a need to.

まう。Precise parts cannot be obtained. Further, in the case of A/B) 8/2, defects such as uneven density and clogging appear in the molded product.
