In China, the consumption of the MoSi2 heating element continues to increase with development and upgrading of industries. However, the MoSi2 heating element .from local manufacturers still has poor quality and thus results in waste of precious molybdenum resource. In this review, the recent research results of production process of MoSi2 heating elements were briefly summarized. The purity and particle size distribution of starting MoSi2 powder as well as the mixing and sintering processes were identified as major impact fators on the performance of MoSi2 heating elements. This review points out the improving direction for local MoSi2 heating elements.展开更多
