A liquid metal matrix thermal paste comprises a dispersion of non-reacting thermally conductive particles in a low melting temperature liquid metal matrix. The particles preferably are silicon, molybdenum tungsten or, other materials which do not react with gallium at temperatures below approximately 100°C. The preferred liquid metals are gallium and indium eutectic gallium and, tin eutectic and gallium, indium and tin ternary eutectic. The particles may be coated with a noble metal to minimize surface oxidation and enhance wettability of the particles. The liquid metal matrix thermal paste is used as a high thermally conducting paste in cooling high power dissipation components in …

Why it's free to use
- Filed June 13, 1990 and granted November 9, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 13, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
