Definitions

  • the present invention relates to a boron nitride sintered body composed of boron nitride alone or boron nitride and another ceramic component, and a method for producing the same.
  • BN Powder of boron nitride
  • a small amount of oxide such as ⁇ 2 ⁇ 3 or Ca 0 is added to the BN powder as a sintering aid.
  • oxide such as ⁇ 2 ⁇ 3 or Ca 0
  • the present invention has been made in view of the above problems, high purity, you to obtain a large double ⁇ shaped BN sintered body strength Sintered its purpose a
  • amorphous BN powder is not added to the raw material BN powder or a powder that forms amorphous BN in the sintering process is added, high-density, high-strength sintering is performed at normal pressure without using a sintering aid. Solidification is obtained.
  • the entire amount of the starting material of the BN component can be replaced with the above-mentioned amorphous BN powder or a powder that produces amorphous BN.
  • the compounding amount of ⁇ -lfas BN powder in the starting material of the BN component or the powder that produces amorph ⁇ is more than 5% by weight. Good.
  • a part of or all of the BNI component as a starting material is made into amorphous B powder, and after the raw material powder has been carved, it is manufactured in a reduced nitriding atmosphere and then reduced in size. Law.
  • a part or all of the starting material of the BN component is converted into powder that forms amorphous BN in the sintering process, and after forming the raw material powder, it is sintered in a reduced nitriding atmosphere H.
  • a method for producing a sintered body is produced.
  • the amount of “powder that produces amorphous BN by sintering” in the starting material of the BN component is at least 5% by weight of the BN component powder, and is described in £ 3. Production method of a silicon nitride sintered body.
  • a feature of the present invention is that at least a part of the BN component as a starting material is Rufus BN powder or a powder that produces amorphous BN in the sintering process.
  • the amount of the powder is preferably 5% by weight or more of the starting material of the BN component. The reason is that if it is less than 5% by weight, the strength is low and it is not practical.
  • a typical example of a powder that produces amorphous BN during the sintering process is boron (B) powder.
  • B boron
  • the temperature is changed to a relatively low temperature of 8 N, and when the temperature is extremely high, a stable high quality is obtained. Therefore, boron changes to amorphous at a temperature below the sintering temperature, and the sintering reaction is substantially in the same form as sintering of non-atomic powder.
  • boron nitride laminate when blending BN with other tz laminates (eg, silicon nitride, aluminum nitride, oxides such as alumina, etc.), the distribution of t To less than 50% by weight, the characteristics of boron nitride laminate can be secured.
  • tz laminates eg, silicon nitride, aluminum nitride, oxides such as alumina, etc.
  • Example 2 1 The following were prepared as raw material powder
  • boron nitride-based sintered body can be obtained even under normal pressure sintering, and (2) a sintered complex with a complicated shape can be easily obtained. Obtainable.
  • the boron nitride-based sintered body of the present invention is used as, for example, various electrical components.
