Abstract
A method of forming a heat transfer fluid includes dispersing an aluminum oxide powder in water to form a slurry; combining the slurry with water to form a first combination; adding a first amount of a chelating agent to the first combination to form a second combination; adding a first amount of a surfactant to the second combination to form a third combination; adding one of the group consisting of propylene glycol and ethylene glycol to the third combination to form a fourth combination; adding a second amount of the chelating agent to the fourth combination to form a fifth combination; adding a second amount of the surfactant to the fifth combination to form a sixth combination; and mixing the sixth combination to form the heat transfer fluid.
