Abstract:
Molybdenum disilicide nanocomposite powder was produced successfully in Iran Materials and Energy Research Center, in addition to titanium carbide.

Iranian Researchers Find New Way to Produce Molybdenum Disilicide Nanocomposite

Tehran, Iran | Posted on November 5th, 2012

The powder was produced via an in-situ synthesis from the mixture of molybdenum, silicon, titanium, and carbon powders through mechanical alloying method.

Raw materials of MoSi2 have been used as thermal elements in air atmospheric furnaces for years. Fragility at high temperatures is the main problem of this component. However, the problem can be solved by making nanocomposite and by decreasing its particle size down to nanometric scale.

"The purpose of the research was to study the feasibility of the synthesis of the nanocomposite from molybdenum, silicon, titanium, and carbon powders. In this regard, we studied the effects of parameters such as milling time and the ratio of the mill weight to the powder weight (BPR) on the reactions. We also studied the feasibility of the synthesis in various circumstances," Mohammad, one of the researchers of the plan, told the news service of Iran Nanotechnology Initiative Council.

In the past, MoSi2 and TiC powders were separately produced and mixed to obtain the desired composite. It sometimes resulted in heterogeneous distribution and improper meshing. However, in the production of this composite from the mixture of pure powders, the background and strengthening phases are produced simultaneously, and the problem of particle distribution of the strengthening phase has been solved. The meshing problem has been solved too, and the composite has homogenous meshing at nanometric scale.

Results of the research have been published in March 2012 in Ceramics International, vol. 38, issue 2, pp. 1353-1357.
