The Joining of Oxide Ceramics with Quartz Fiber by Interlayer
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.
