Abstract

Despite the fundamental nature of sintering and its importance as a low cost fabrication process, little information exists on the sintering behavior of the structural silicide Mosi2. The sintering of commercial Mosi2 powders in the range of 1-10 μm was investigated as a function of sintering temperature, sintering time, and sintering atmosphere. Initial densities for uniaxially cold pressed powders were in the range of 47-56% theoretical. A maximum sintered density of 90% of theoretical was achieved for 1 μm Mosi2 powders after sintering for 100 hours at 1600 °C in an argon atmosphere. Larger 10 μm Mosi2 powders achieved lower sintered densities under these conditions. Avenues to optimize the sintering behavior of Mosi2 are suggested.
