MOLYPAUL CLAIM PARTICLE SIZE FOR MoS2 DOWN TO QUARTER‐MICRON Available to Purchase

The advantages of Molybdenum Disulphide powders for dry lubrication under extremes of temperature are well known and these products have solved a great number of extremely dfficult lubrication problems where conventional lubricants have completely failed. It is also known that, although liquid dispersions of Molybdenum Disulphide provide most valuable lubricants for many industrial purposes, it is in dry lubrication that MoS2 has proved the most valuable. This is probably because, hitherto, quasi‐colloidal dispersions lose some of the advantages of the dry powders, possibly due to oxidation. Again, this may, in turn, be due to the fact that the particle size of these powders has, up to now, not been smaller than three‐quarters of a micron and usually ranging from this size up to three microns.
