Enhancement of Properties and Performance of MoSi2-based Heating Elements via Low Temperature Sintering



Investigation on properties and performance of MoSi2-based heating elements was carried out using high temperature sintering (HT), low-high temperature sintering (LHT), and low temperature sintering (LT) processes. Flexural strength depends proportionally on the thickness of protective surface scale, which is determined by the sintering temperature. The performance, indicated as critical damage temperature, is significantly correlated with the degree of densification, embodying dramatic deterioration with increasing porosity. LHT is more promising in industrially producing high-performance MoSi2-based heating elements because of advantages in densification and efficiency compared with HT and LT.
