The Joining of Oxide Ceramics with Quartz Fiber by Interlayer

Abstract:

The joining of ZrO₂ ceramic and quartz fiber was realized by glass interlayer heat-treatment at 800 °C for 1h. Using the low-temperature liquid reaction of B₂O₃-SiO₂ and B₂O₃-ZrO₂ and the properties change of borosilicate glass, the two kind materials of different thermal expansion coefficients achieved joint by B₂O₃ as the interlayer material. Through observing the micro-morphology of joint samples at different heat-treatment temperature, and combining with the fibers’ high temperature properties, the optimum joining temperature was investigated. According to the phase diagrams of B₂O₃-SiO₂ and B₂O₃-ZrO₂ and SEM results of joints region, the joint mechanism of density ceramics and fiber weaves was discussed in detail.
