Popis: Examination with the electron microscope indicates that the soap particles contained in calcium soap lubricating greases have an unusual structure. They are about 1 μ long, and consist of fibers coiled in spiral forms, or of two twisted together in a ropelike manner. The effect of two factors on the form of the dispersed soap particles was investigated. The addition of water to stabilize a dispersion of calcium soap in mineral oil was found to orientate the soap particles from minute, nondescript form to fibers having a wavy, loosely coiled appearance. The shearing action associated with the mixing of the grease during its preparation caused the fibers to assume a spiral or twisted form.
