SiC/(W, Ti)C ceramic composites with different content of (W, Ti)C solid-solution were produced by hot pressing. The effect of (W, Ti)C content on the microstructure and mechanical properties of SiC/(W, Ti)C ceramic composites has been studied. Densification rates of the SiC/(W, Ti)C ceramic composites were found to be affected by addition of (W, Ti)C. Increasing (W, Ti)C content led to increase the...
The effects of WO 3 on properties of MgO-based refractories were studied and microstructures analyzed using scanning electron microscopy (SEM) and EDS. WO 3 can improve the sintering of MgO-based refractories. <2wt% WO 3 is favorable to improve the cold modulus of rupture of MgO-based refractories, but high levels of WO 3 have a negative effect on cold MOR and thermal...
