説明する。Hereinafter, the case where a non-oxide ceramic sintered body is formed from a silicon carbide sintered body will be explained together with the respective conditions.
非酸化物セラミック焼結体を炭化珪素焼結体てもって形
成する場合は、丁記（ａ）及び（ｂ）工程からなる製造
方法を適用することか有利である。When a non-oxide ceramic sintered body is formed using a silicon carbide sintered body, it is advantageous to apply the manufacturing method consisting of steps (a) and (b).

得られた生成形体（Ｉｌａ）を非酸化性雰囲気中で１７
００〜２：１００°Ｃの温度に加熱して焼結する工程。(a) A mixed powder of silicon carbide powder with an average particle size of 10 gm or less, a sintering aid, a carbonaceous additive, and a forming aid is used, and a solid lubricant (12) is placed at the desired location. Generated form (
(b) Molding the formed body (Ila) obtained in step (a) above in a non-oxidizing atmosphere for 17
00-2: A step of heating and sintering at a temperature of 100°C.
この場合、平均粒径か１０ｇｍ以下の炭化珪素粉末を使
用する理由は、平均粒径かｌ０ｇｍ以下の粉末は生成形

素粒子相互の結合か極めて生じ易く、高密度で高強度の
焼結体を得ることかてきるからである。特に、前記炭化
珪素粉末は平均粒径か５ｇｍ以下であることか有利てあ
る。In this case, the reason why silicon carbide powder with an average particle size of 10 gm or less is used is that the powder with an average particle size of 10 gm or less has a relatively large number of contact points with the particle phase W when forming the formed body (Ila), and Since the thermal activity at the firing temperature is large and the diffusion and movement of atoms between silicon carbide particles is significant, mutual bonding of silicon carbide particles is extremely likely to occur, and a high-density and high-strength sintered body can be obtained. This is because it comes. In particular, it is advantageous that the silicon carbide powder has an average particle size of 5 gm or less.
ところて、前記炭化珪素の結晶型にはα型結品、β型結
晶及び非晶質のものかあるか、本発明によれば、前記炭
化珪素粉末はβ型結晶の炭化珪素を少なくとも３０％含
有する炭化珪素粉末であることが好ましい。その理由は
、β型結晶は比較的低温で合成される低温安定型結品で
あり、焼結に際して炭化珪素粒子相互の結合か起こりや
すく。By the way, the crystal type of silicon carbide includes α-type crystal, β-type crystal, and amorphous.According to the present invention, the silicon carbide powder contains at least 30% β-type crystal silicon carbide. It is preferable that it is a silicon carbide powder containing. The reason for this is that β-type crystals are low-temperature stable crystals that are synthesized at relatively low temperatures, and bonding between silicon carbide particles is likely to occur during sintering.
高密度で高強度の焼結体を製造できるからであり、なか
でもβ型結晶を５０％以上含有する炭化珪素粉末である
ことか有利である。This is because a high-density and high-strength sintered body can be produced, and it is particularly advantageous to use silicon carbide powder containing 50% or more of β-type crystals.
また、焼結助剤及び炭素質添加剤か混合される理由は、
焼結助剤及び炭素質添加剤は焼結に際して炭化珪素の焼
結を促進させる作用を有するものてあり、焼結に際して
炭化珪素粒子相互の結合を強め高強度の焼結体を製造す
ることかてきるからである。Also, the reason why sintering aids and carbonaceous additives are mixed is as follows.
Sintering aids and carbonaceous additives have the effect of promoting sintering of silicon carbide during sintering, and they strengthen the bonds between silicon carbide particles during sintering to produce a high-strength sintered body. Because it will come.

) is advantageously between 0.01 and IO% by weight. The content is 0. The reason why it is advantageous to set the concentration to 10% is that the content is 2 to 0%. This is because if it is less than the original weight percent, the effect of promoting the bonding between silicon carbide particles during sintering will be small, and sintering must be performed at a relatively high temperature. This is because silicon carbide loses its original properties due to the increased amount of carbon contained in the sintered body.

とか右利である。When the free carbon is present at the same time as the sintering aid, it is effective in optimizing crystal growth and producing a high-strength silicon carbide sintered body. It must be less than 5% of the generated form (I la) at the time of formation, or it is right-handed.

るためである。Furthermore, the sintering temperature in step (b) is 1700~2300''
The reason why C is preferable is that at temperatures lower than 1700°C, the yield of the sintered body decreases! This is because since the amount of the sliding member (12) is small, the solid-to-solid lubricant (12) is insufficiently fixed, making it difficult to form a sliding member (lO) with excellent sliding properties. Also, 23
This is because when heated to a temperature higher than 00°C, the strength of the silicon carbide sintered body tends to decrease because the crystals of the silicon carbide sintered body become coarse or silicon carbide begins to sublimate. .
