摘要

Electrical property of joints made with polymer-derived silicoaluminum carbonitride (SiAlCN) ceramics was investigated. SiAlCN ceramics were successfully joined using polycarbosilane precursor as joining medium at 1123 K and 250 kPa. The maximum tensile strength of obtained joints reached ~3 MPa, meeting strength requirement of sensor fabrication. DC and AC conductivity of joints were measured in temperature range of 373–823 K, and were shown to follow band tail hopping mechanism. Conductive behavior of joints was evaluated via comparison with free SiAlCN ceramics. Unique amorphous structures of SiAlCN substrate and joining layer played important role in overall electrical properties. Therefore, the prepared joints presented practical application in high-temperature sensors based on polymer-derived ceramics.
