Improving the Suspension Property of Non-Plastic Material Slurry with Lecithin


Article Preview

Lecithin is a natural amphipathic surfactant. In this paper, lecithin was experimented to improve the suspension property of non-plastic materials with aluminum oxide slurry. The suspension property was compared by adding different types and amounts of lecithin into the aluminum oxide slurry in acid and alkaline conditions. The experiments showed that the 6090-type lecithin with the optimal amount (0.2%) of dry base best modified the suspension property of the aluminum oxide slurry.
