Additives, high temperature steam and CO2 are effective methods to reduce the viscosity. The viscosity property and colloidal stability variation of samples with or without additive were studied.
Some tests were made on colloidal borates of different constitution with respect to the antiwear property. It was found that hydrated sodium metaborate possessed the best antiwear property.
