- the average crystal grain size on the surface of the ceramic sintered body is large, the ratio of the area on the surface of the sintered surface of the crystal grain boundary that is easily corroded by plasma decreases. For this reason, it becomes difficult for particles to fall off when the burnt skin surface is exposed to a plasma gas. Therefore, since it is located in the vicinity of the outlet 16, it is possible to satisfactorily reduce the generation of particles in the first region 21 that is more easily exposed to plasmad gas than the second region 22. Therefore, the adhesion of particles to the object 2 can be reduced, and the occurrence of defects in the object 2 can be suppressed.
- the mechanical strength of the surface of the ceramic surface increases. Therefore, in the second region 22 which is located inside the main body 12 and is less exposed to the plasmad gas than the first region 21, the mechanical strength is increased while reducing the influence of the plasmad gas. Damage to the main body 12 due to mechanical stress or thermal stress can be suppressed.
- the average crystal grain size in the first region 21 is desirably 1.5 times or more than the average crystal grain size in the second region 22. As a result, the generation of particles in the first region 21 can be favorably reduced. Further, the average crystal grain size in the first region 21 is desirably 10 times or less than the average crystal grain size in the second region 22. The average crystal grain size in the first region 21 is, for example, 3 ⁇ m or more and 20 ⁇ m or less. The average crystal grain size in the second region 22 is, for example, 2 ⁇ m or more and 10 ⁇ m or less.
- the inner wall of the first hole portion 18 is a burnt surface
- the inner wall of the second hole portion 19 is a processed surface such as a ground surface or a polished surface. Therefore, since the inner wall of the first hole 18 that is easily exposed to plasma gas because it is located on the outlet 16 side of the second hole 19 is made of a burnt surface, the generation of particles can be reduced well. Can do.
- the second hole portion 19 can improve the accuracy of the position and shape by machining as compared with the case where the inner wall is made of a burnt surface.
- the second hole portion 19 which is located on the inlet 17 side of the first hole portion 18 and is not easily exposed to plasma gas, the influence of the plasma gas is reduced, and the position and shape accuracy are increased. Further, gas leakage due to poor connection between the gas nozzle 5 and the gas supply pipe 4 can be suppressed.
- the third region 23 located in the vicinity of the inflow port 17 is formed by a processing surface such as a grinding surface or a polishing surface, and thus is caused by poor connection between the gas nozzle 5 and the gas supply pipe 4. Gas leakage can be suppressed satisfactorily.
- the third region 20 is preferably a region having a distance of 5 mm or less from the inflow port 17.
- the one end surface 13 of the main body 12 is made of a sintered surface of a ceramic sintered body.
- the one end face 13 that is easily exposed to plasma gas is a burnt surface, the generation of particles can be reduced satisfactorily.
- the burnt surface is continuously formed from the one end surface 13 of the main body 12 to the first region 21 of the through hole 11. As a result, the generation of particles can be reduced favorably.
- the one end surface 13 may be a processed surface such as a ground surface or a polished surface. In this case, it is desirable that the one end surface 13 is a polished surface from the viewpoint of suppressing the falling off of the particles.
- the other end surface 14 of the main body 12 is preferably made of a ground surface or a polished surface of a ceramic sintered body.
- a main body sintered body 25 which is a ceramic sintered body before the through hole 11 of the main body 12 is formed is prepared. Specifically, for example, the following is performed.
- pure water and an organic binder are added to the ceramic powder, and then wet mixed with a ball mill to prepare a slurry.
- the slurry is granulated by spray drying to form a ceramic powder.
- the ceramic powder is molded into a predetermined shape using a molding method such as a die pressing method or a cold isostatic pressing method (CIP molding method), and the cylindrical shape shown in FIG.
- the molded body 26 is obtained.
- a recess 27 that opens to the one end surface 13 that forms the first hole 18 described above is formed in the molded body 26 by cutting.
- firing is performed at, for example, 1400 ° C. or more and 2000 ° C.
- the molded body 26 is fired by placing the molded body 26 on the mounting table 28 of the firing furnace while exposing the one end surface 13 with the recess 27 opened as an upper side. It is done in the state.
- the inner wall of the recess 27 has a first region 21 located near the one end surface 13 in the first region 21 than the first region 21. Compared with the second region 22 located inside the molded body 26, large heat is likely to be applied.
- the molded body 26 is fired. Liquid phase sintering occurs. For this reason, the crystal of the first region 21 to which heat larger than that of the second region 22 is applied is likely to grow larger than that of the second region 22. As a result, the average crystal grain size in the first region 21 can be made larger than the average crystal grain size in the second region 22 on the inner wall of the recess 27 of the main body sintered body 25.
- the first hole 18 having a diameter as small as 0.1 mm or more and 2 mm or less it is necessary to reduce the diameter of the recess 27 serving as the first hole 18. It becomes difficult to flow. Therefore, when the molded body 26 is baked, the heat applied to the inner wall of the recess 27 is likely to be uneven, and the heat applied to the first region 21 is likely to be greater than the heat applied to the second region 22. Therefore, the average crystal grain size in the first region 21 is likely to be larger than the average crystal grain size in the second region 22 on the inner wall of the recess 27 of the main body sintered body 25.
- the recess 27 has a bottom surface at the end opposite to the one end surface 13 and does not penetrate the main body 12. As a result, it becomes difficult for air to flow in the recess 27. Therefore, the average crystal grain size in the first region 21 is likely to be larger than the average crystal grain size in the second region 22 on the inner wall of the recess 27 of the main body sintered body 25.
- the molded body 26 As a molding method for forming the molded body 26, it is desirable to use a CIP molding method. According to the CIP molding method, since the pressure during molding is uniformly applied, the density of the molded body 26 can be made uniform. Therefore, when the molded body 26 is fired, crystal grains grow uniformly according to the applied temperature. As described above, the first region 21 is heated by applying heat larger than that of the second region 22 to the first region 21. The average crystal grain size in 21 is easily made larger than the average crystal grain size in the second region 22.
- Hole processing is performed from the other end surface 14 side of the main body sintered body 25 using grinding, and the second hole portion 19 that opens to the other end surface 14 and is connected to the recess 27 is formed in the main body sintered body 25. . Accordingly, the recess 27 becomes the first hole 18, and the through-hole 11 constituted by the first hole 18 and the second hole 19 can be formed. Moreover, the other end surface 14 is ground by using a grinding process to obtain a ground surface. As a result, the main body sintered body 25 can be the main body 12. In addition, you may use ultrasonic processing as a grinding process.
- the one end surface 13 can be made to be a burnt skin surface by not performing processing such as grinding or polishing on the one end surface 13.
- the grilled surface is continuously formed from the one end surface 13 of the main body 12 to the first region 21 of the through hole 11.
- the end surface 13 may be subjected to processing such as grinding or polishing.
- the processing amount along the longitudinal direction of the main body sintered body 25 is desirably, for example, not less than 0.5 mm and not more than 2 mm. As a result, the first region 21 can remain in the main body 12.
- the inner wall of the second hole 19 becomes a ground surface.
- the inner wall of the 2nd hole part 19 can be made into a grinding
- the other end surface 14 can be used as a polishing surface by polishing the other end surface 14.
