There is a method of adding oxide powder such as MgO to β-SiAlON raw material powder and sintering it, but the sintered body obtained by this method has improved room temperature strength, but has decreased strength at high temperatures.

It has been discovered that the desired β-sialon sintered body can be obtained by sintering a powder composition obtained by adding a predetermined amount to sialon raw material powder, and based on this knowledge, the present invention has been completed. It came to this.

Each component of is Si 6-X Al X O X N 8-X (however,

It is desirable that the particles be 50 μm or less, preferably 20 μm or less. If particles with a particle size larger than 50 μm are contained, they remain as unreacted substances in the obtained sintered body, significantly reducing the strength of the sintered body.

It is generally well known that SiC is itself a hard material and does not lose strength at high temperatures. However, the level of this compound is significantly lower than that of β-sialon, and depending on the amount added, β-sialon's original characteristics of oxidation resistance and low reactivity with molten metal may be affected. will cause you to lose. Therefore, in the present invention, the compound powder is blended in an amount of 5 to 40 parts by weight to 95 to 60 parts by weight of the β-sialon raw material powder, assuming the total amount is 100 parts by weight.

A powder mixture containing silicon carbide powder can be prepared by a method conventionally used for producing ceramic sintered bodies.
For example, sintering can be performed by a reaction sintering method, a hot press method, an atmosphere pressure sintering method, a HIP method, or the like.
緻密な焼結体を得るためには、焼結条件とし
て、不活性雰囲気下、1600〜2200℃の温度、常
圧、好ましくは100〜500Kg／cm2の圧力で焼結を行
うことが望ましい。 In order to obtain a dense sintered body, it is desirable to carry out sintering under an inert atmosphere at a temperature of 1600 to 2200°C and normal pressure, preferably at a pressure of 100 to 500 kg/cm 2 .
焼結温度が1600℃未満では反応は十分に進行せ

においては、焼結温度が1900℃より高いと生成し

などにおいては、その雰囲気の圧力を、該β―サ
イアロンの分解を抑制しうる圧力まで高めること
によつて、該焼結温度を2200℃まで上昇させるこ
とが可能である。 If the sintering temperature is lower than 1600°C, the reaction will not proceed sufficiently, resulting in a sintered body with low density. In addition, in the normal sintering method, if the sintering temperature is higher than 1900℃, the generated β-sialon will thermally decompose, making it impossible to obtain a dense sintered body, but atmospheric pressure sintering method and HIP method In this case, the sintering temperature can be raised to 2200° C. by increasing the pressure of the atmosphere to a pressure that can suppress the decomposition of the β-sialon.
焼結時間は通常15時間内、好ましくは１〜８時

高圧の条件下では焼結時間が短縮されることはも
ちろんのことである。 The sintering time is usually within 15 hours, preferably in the range of 1 to 8 hours. If the time is too short at a low temperature, the reaction will be insufficient and the sintered body will not be densified.
Moreover, if it exceeds 15 hours, the crystal particles may grow abnormally or decompose. Since this sintering time depends on the temperature and pressure during sintering, it goes without saying that the sintering time is shortened under high temperature and high pressure conditions.
本発明方法においては、焼結は非酸化性雰囲気

サイアロンの熱分解を防ぐためである。 In the method of the invention, sintering is carried out under a non-oxidizing atmosphere, for example under nitrogen or an inert atmosphere containing nitrogen.
Alternatively, it is carried out in an atmosphere containing nitrogen and carbon monoxide. This prevents the oxidation of the raw material powder and the produced β-sialon.
This is to prevent thermal decomposition of Sialon.

ある。 The formation of β-SiAlON is generally thought to occur due to the dissolution reaction of Si 3 N 4 and AlN in the x-phase, which has a high oxygen content, and the densification of the sintered body progresses. In the production and sintering process of β-sialon, carbides such as silicon carbide promote sintering even when added in small amounts, and the strength of the resulting β-sialon sintered body is significantly improved.
Furthermore, it has become clear that by arbitrarily changing the amount of silicon carbide added, not only the strength but also the thermal conductivity of the sintered body can be greatly improved. From this point of view, the amount of silicon carbide added in the method of the present invention improves the strength of the sintered body,
In addition, in order to maintain the excellent properties of the β-sialon sintered body, β-sialon raw material powder is added at 95 to 60% by weight.
It is necessary that the amount is in the range of 5 to 40% by weight.
このようにして、炭化ケイ素を添加して得られ

なり、高温における強度低下を生じない。 In this way, in the β-SiAlON sintered body obtained by adding silicon carbide, a part of the added silicon carbide diffuses into the generated x phase and grain boundary phase, and the crystals in the grain boundary phase development is promoted. In this way, by promoting crystallization at the grain boundary phase, it has superior high-temperature properties compared to products containing oxides such as Y 2 O 3 and MgO as additives. No decrease in strength occurs.

品に有効に用いられる。 The high-strength heat-resistant ceramic sintered body obtained by the method of the present invention has excellent oxidation resistance, low coefficient of thermal expansion, high thermal shock resistance and corrosion resistance against molten metal, and has excellent high-temperature strength. Due to its properties, it can be effectively used as a high-temperature structural material in various devices and parts.
