In situ studies of oxidation of ZrB2 and ZrB2–SiC composites at high temperatures

TEM Study of the High‐Temperature Oxidation Behavior of Hot‐Pressed ZrB2–SiC Composites

“…The batches consisted of 70 vol% of ZrB 2 powder and 30 vol% of SiC powder. Many previous studies have reported that ZrB 2 ‐ 30 vol% SiC composites showed improved sinterability and mechanical properties, and notably high‐temperature oxidation resistance . Therefore, composites with 70 vol% ZrB 2 and 30 vol% SiC were used for the oxidation tests in this study.…”

Microstructure evolution of SiC-ZrB2-ZrC coating on C/C composites at 1773 K under different oxygen partial pressures

“…Numerous attempts have been made to investigate the oxidation behavior and mechanism of ceramic matrix composites in air [15][16][17][18][19]. The research of Wang et al illuminated that a four-layered structure was formed during the oxidation of ZrB 2 -SiC-ZrC ceramics [20].…”

A novel method to evaluate Young׳s modulus of ceramics at high temperature up to 2100°C

“…Homogeneous graphite was prepared by isostatically pressed method. Moreover, three-phase mixture of C/SiC/ZrB 2 is also a kind of typical UHTCs and performs high fracture toughness and strength [27,28], as well as excellent thermal shock [29] and oxidation resistance [30] up to 1800 1C. In fact, Young's modulus at high temperature seems not being recognized correctly so far.…”
