Borides are advanced materials for use as fuel additives for energetic systems. The potential of use of metal powders (Al, Mg and others) is almost exhausted today. New additives with higher energy characteristics are required.

The use of potentially high boron exothermicity becomes possible if it is used in the form of metal borides which also have high values of the heat of combustion. It was found that borides of Al and Mg as well as Ti and Zr are the most promising ones.

This paper describes a laboratory technology of production of borides of Al, Mg etc. including double and mixed compounds. Elemental boron, boron carbide, iron boride were used as boron source. The experimental results of particle size analysis, XRD-analysis, TGA for synthesized powders in compare with pure B and Al are given.

Ignition delay and burning rate for AlB2 are determined. The same research for model mixture of borides with binder also are analyzed. Preliminary studies have indicated that it is possible to produce borides with control and high content of target phase for applications in high energy materials..
