Preparation of high-content MoAlB by thermal explosion from Mo/Al/B2O3 system
MoAlB ceramics containing a small amount of Al2O3 and MoB as impurities were synthesized by thermal explosion technique using Mo, Al, and B2O3 as the raw materials. The effect of Al content on the reaction synthesis of MoAlB materials was investigated. Results showed that adding excess Al could comp...

description | MoAlB ceramics containing a small amount of Al2O3 and MoB as impurities were synthesized by thermal explosion technique using Mo, Al, and B2O3 as the raw materials. The effect of Al content on the reaction synthesis of MoAlB materials was investigated. Results showed that adding excess Al could compensate for the Al volatilized during the thermal explosion reaction Moreover, it could remarkably promote the formation of gaseous AlO and inhibit the synthesis of solid-phase Al2O3. Thus, it substantially promoted the synthesis of MoAlB. High-content MoAlB ceramics were prepared at 800 °C for 1 min by using 2Mo/4.6Al/B2O3 as the raw materials. The MoAlB grains were flaky and had a thickness of 500 nm and a length of 1–5 μm. |
