Definitions
- the present invention relates to a synthetic corundum (Al 2 O 3 ) used as a material of a flow cell incorporated in a micrometer for measuring fine particles contained in a liquid such as hydrofluoric acid, calcium fluoride (CaF 2 ) used as an optical component,
- the present invention relates to a method of joining magnesium fluoride (MgF 2 ) crystals.
- a flow cell made of synthetic corundum a plurality of plate-like synthetic corundum pieces are prepared, and these synthetic corundum pieces are joined.
- an adhesive is used, a boundary surface is formed on the joint surface, and light is refracted or reflected.
- heat-sealing there is a problem that bubbles are contained in the joint surface.
- Patent Documents 1 to 3 The bonding methods disclosed in Patent Documents 1 to 3 are basically the same. First, a synthetic corundum piece is cut out from the crystal block, the bonding surface of the cut out synthetic corundum piece is polished, and the polished surfaces are joined together. The two synthetic corundum pieces in the combined state are strongly pressed against one end side so that the distance between the two synthetic corundum pieces is such that interference fringes can be formed. In this state, the two synthetic corundum pieces are melted with the melting point of the synthetic corundum (2030). C.) or less, by gradually heating from one end side to the other end side, a close contact state is obtained.
- one end side of the strongly pressed state is in an optical contact state or a chemical pressure contact state, and interference fringes are eliminated by heating, so this contact state is considered to continue to the other end side.
- combination corundum pieces joined in this way do not have an optical interface, and an extremely excellent three-dimensional structure is obtained.
- the reason why the yield is not sufficient is to press the one end side more strongly than the other end side so that a gap is formed between the joint surfaces so that interference fringes are formed. Since it is not restrained, it is considered that the fine gap formed between the synthetic corundum pieces on the other end side is not constant. This problem also occurs when a crystal of magnesium fluoride (MgF 2 ) or calcium fluoride (CaF 2 ) is joined.
- MgF 2 magnesium fluoride
- CaF 2 calcium fluoride
- a crystal piece joining method is a method in which crystal face pieces such as synthetic corundum, calcium fluoride, or magnesium fluoride that are joined to each other are joined together.
- One end side of the body piece is pressed more strongly than the other end side to form an interference fringe on the mating surface, and in this state, the crystal piece is heated at a temperature equal to or lower than the melting point of the crystal body, thereby
- a fine spacer made of a material that can be crushed by pressure during heating is interposed between the other ends of the crystal pieces to be bonded to each other.
- the spacer does not prevent the interference fringes from disappearing by the heat treatment, that is, the collapsibility (elasticity) to such an extent that the crystal pieces to be bonded do not interfere with the optical contact or the chemical pressure contact state. Softness).
- the spacer is cotton fiber, but is not limited thereto. Further, since the size of the spacer forms a necessary interference fringe, it has a diameter of approximately 15 to 60 ⁇ m although it varies depending on the joining length of the synthetic corundum piece.
- the number of stripes per unit length of the combined crystal pieces is determined before the heat treatment.
- the quality of the temporarily joined state can be determined.
- the interval between the crystal pieces on the other end side is set as a spacer. Because it can be controlled accurately, the yield can be increased.
- the quality of the temporary bonding state can be determined. Can be increased.
- the part where the mark of the pressing jig is attached becomes only a part, and after joining There are fewer non-conforming parts and there is no waste of material.
- FIG. 1 is a side view showing a state in which two synthetic corundum pieces are superposed
- FIG. 2 is a plan view showing a state in which a spacer is placed on the end of one synthetic corundum piece.
- These synthetic corundum pieces 1 and 2 were cut out from the crystal block, cleaned after polishing the surfaces to be joined, and confirmed that there was no fine dust on the joint surfaces.
- two synthetic corundum pieces are overlapped, but three or more synthetic corundum pieces can be overlapped and joined simultaneously.
- the one end side of the synthetic corundum pieces 1 and 2 is strongly pressed or clamped by the jig 4.
- the pressing part by the jig 4 may be the entire area in the width direction, only a part of the center in the width direction is used as in the illustrated example, thereby reducing non-conforming parts after joining.
- a spacer 3 is interposed between the joint surfaces on the other end side of the synthetic corundum pieces 1 and 2.
- the spacer 3 is shown larger than the actual size for the sake of clarity in the figure, but in the embodiment, a cotton fiber having a diameter of 30 ⁇ m is used.
- the spacer 3 is crushed by the pressure acting on the other end side of the synthetic corundum pieces 1 and 2 during the heat treatment after the temporary joining, so that the optical contact or the chemical pressure density on the other end side of the synthetic corundum pieces 1 and 2 is collapsed. Anything that does not interfere with the wearing state is acceptable.
- gel beads or the like can be used, but those that generate a large amount of gas during the heat treatment after temporary bonding are not preferable because bubbles may remain on the bonding surface.
- FIG. 3 is a plan view showing a state in which one end portion of the superimposed synthetic corundum pieces 1 and 2 is pressed. As is clear from this photograph, a fine gap in the joint surface of the superimposed synthetic corundum pieces 1 and 2 is shown. Interference fringes originating from are observed.
- the interval between the interference fringes is proportional to the size of the minute gaps on the joint surface
- counting the number of interference fringes per unit length in the temporary joint state allows the joint surface of the synthetic corundum pieces 1 and 2 to be It can be determined in advance whether or not the minute gap is in an appropriate range. In this embodiment, five stripes are observed per unit length.
- the synthetic corundum piece in the above temporarily joined state is heated to a temperature below the melting point of the corundum and held for a certain period of time. Then, the optical contact or the chemical pressure contact state advances from one end side already in the optical contact or chemical pressure contact state to the other end side, and the gas existing between the synthetic corundum pieces along with this progress. Is completely eliminated, and the entire joining surface is in an optical contact or chemical pressure contact state.
- FIG. 4A is a photograph of two synthetic corundum pieces before joining
- FIG. 4B is a photograph after joining.
- 16 pairs of two synthetic corundum pieces overlapped in the direction perpendicular to the paper surface. It is reflected.
- a passage for allowing fluid to pass is formed in the center.
- the left and right portions sandwiching this passage are surfaces to be joined, and interference fringes are observed before heat treatment.
- the photograph of (b) which shows after heat processing in all the test pieces, the above-mentioned interference fringes were not observed at all and no optical boundary surface was recognized.
- FIG. 5 (a) is a photograph of the front surface of a structure in which three magnesium fluoride crystals are simultaneously bonded
- FIG. 5 (b) is a photograph of the back surface of the structure. It is not observed at all, and it can be seen that no optical interface is recognized.
- FIG. 6 shows a three-dimensional structure manufactured by the method of the present invention.
- This three-dimensional structure 5 includes a base plate 5a made of a synthetic corundum piece and four side plates joined along the sides of the base plate 5a. 5b, 5c, 5d, and 5e, and the base plate 5a and the side plates 5b, 5c, 5d, and 5e, and the butt portions between the side plates are applied with the method of the present invention so that the three-dimensional structure is obtained by a single heat treatment.
- the body 5 is manufactured.
- the method of the present invention can be used not only for synthetic corundum and magnesium fluoride but also for bonding calcium fluoride crystals. Furthermore, although the Example showed the example which joined synthetic
- the method of the present invention is not limited to a flow cell incorporated in a particle meter, but includes various optical parts such as lenses and prisms, mechanical parts that require hardness, and vacuum containers that use characteristics in which the joint surface is sealed, such as a variable wavelength laser.
