Abstract:
To improve the production yield rate of a synthesis corundum cell superior in translucency, chemical resistance or an optical component comprising calcium fluoride. On the other end side of synthetic corundum piece, spacer intervenes between the surfaces which will be bonded. The spacer is crushed flat by pressure force which effects the other end side of synthetic corundum piece in the case of heat-treatment after the temporary bonding. Thereby, the spacer does not disturb the synthetic optical contacting or chemical pressurized fusion bonding state of corundum piece.

Claim (Index 1):
An bonding method of the crystal body piece, put the surfaces of the pieces of the crystal body such as synthetic corundum (Al2O3), calcium fluoride (CaF2)or magnesium fluoride (MgF2) which will be bonded together to each other, strongly press the one end side of two pieces of the crystal body pieces with the condition of putting together, generate an interference fringe between the surfaces put together, dissipate the interference fringe between the surfaces put together by heating the crystal body pieces at a temperature less than the melting point of the crystal body in this state, particularly, insert a minute spacer between the other end side of the crystal body pieces bonded together to each other, the minute spacer consists of material which can be crushed flat by the pressure force at the time of heating.
