研究了两种工业级硬脂酸镁的润滑性能。它们的含水量和晶体结构相似。它们的脂肪酸组成略有差异，但这些差异并不影响润滑性能。润滑性能与颗粒尺寸分布和比表面积有关。这些参数的影响，进一步研究了未经研磨和研磨的化学纯硬脂酸镁。球磨降低了颗粒尺寸，增加了比表面积。在这两种情况下，具有较小粒度和较大比表面积的批料具有相当好的润滑性。
The lubrication properties of two commercial-grade magnesium stearates were studied. Their moisture contents and crystal structures were similar. There were minor differences in their fatty acid composition, but the differences did not affect the lubrication properties. The lubrication properties correlated with particle size distributions and specific surface area. The effect of these parameters was further studied with unmilled and milled chemically pure magnesium stearate. Milling decreased the particle size and increased the specific surface area. In both cases, the batch with a smaller particle size and larger specific surface area had considerably better lubricity.
