Particle stabilized metallic emulsions or monotectic metallic systems with stabilized droplet size can be produced of different alloys for different purposes, such as solid lubricants or heat storage materials.

Our company has developed a new class of materials: particle stabilized metallic emulsions, or in other words monotectic metallic alloys with stabilized droplet size of the minority phase. These alloys can be produced from different metals with different average droplet size and different phase ratios of the minority phase.

These advanced metallic materials can be used as advanced solid lubricants to replace traditional lubricants (oil). This will allow increasing the temperature of engines, which would lead to their enhanced efficiency. The same can be used as advanced heat storage materials with the minority phase melting and solidifying in the heating /cooling cycles. As the matrix is a liquid metal of high heat conductivity, the rate of storing and recycling heat is much faster compared to the conventional salt systems. These materials have low viscosity, so they can serve as heat transfer materials.
