Microwave Plasma Chemical 

Synthesis Machine

Winner of the:

Microwave Plasma Chemical Synthesis (MPCS) utilizes microwave energy to generate a plasma by ionizing the gases. The resulting high temperature vaporizes the precursors which facilitates initiating and sustaining the chemical reactions at molecular levels in the presence of microwaves. These vapors are then rapidly quenched resulting in the formation of nanopowders.

The advantages of this technique are:

• Narrow particle size distribution
• High purity
• Can handle various kinds of precursors-powders, gases and liquids
• Capable of producing metallic, ceramic and alloy powders
• Highly energy efficient
• Scaleable - presently 1 to 10 Kg per day

Typical powders that are custom made and available for sale includes:

The following are TEM micrographs of metal nanopowders synthesized using MMI's microwave plasma chemical synthesis process.

Prices vary from $1/gm to $5/gm depending on the material and the quantity. We can also deposit nanopowders on ceramic substrates.
