PURPOSE:To bond quartz components while preventing the presence of bubbles on the bonding surfaces and contamination of quarts by tying the quartz components with a high-m.p. wire rod with a specified metal piece or rod in between, and heating and bonding the parts. CONSTITUTION:The quartz components 4 such as an analytical quartz cell obtained by combining four side plates and one bottom plate is tied by a high-m. p. wire rod 2 such as a tungsten rod with the metallic piece or rod 3 (e.g., Cr) having >=1,750 deg.C m.p. and >=2.5X10<-4>/ deg.C thermal expansion coefficient in between, and heated. The loosening of the tying force due to the thermal expansion of the wire rod 2 is compensated with the expansion of the metal piece or rod 3, and the members are heated and bonded while keeping the tying force. |
