Abstract

The invention discloses a hollow glass microsphere. The hollow glass microsphere is prepared by a soft-chemistry method; a thin wall of the hollow glass microsphere contains the ingredients in content (by weight): 55-88% of silicon dioxide, 3-30% of boron oxide, 2-32% of sodium oxide, 0-15% of calcium oxide, 0-5% of aluminum oxide, 0-5% of magnesium oxide, 0-5% of potassium oxide and 0-2% of lithium oxide, and has the density of 0.1-0.7g / cm<3>. The hollow glass microsphere is high in compressive strength, good in fluidity and dispersity and thin and uniform in wall and is lightweight, low in alkali content and waterproof.
