    摘要: There is provided hollow microspheres comprising: at least 45 wt % of recycled glass based on the total weight of a feed composition from which the hollow microspheres are derived, wherein the hollow microspheres have a density of less than 1.25 g/cm 3 , strength at 20% volume reduction greater than 20 MPa and have a substantially single cell structure. There is also provided hollow microspheres comprising: a blend of recycled glass and glass feed, wherein the hollow microspheres have a density of less than 1.25 g/cm 3 and are made from a feed composition that is essentially free of an added effective blowing agent. There is provided a method for making hollow microspheres.

    摘要: Glass particles comprise glass microbubbles. The glass particles have a size distribution with a d 50 in the range of from 15 to 100 microns, and have a true density of less than 0.7 g/cm 3 . The glass particles comprise, on an equivalent weight basis: from 50 to 70 weight percent silica; from 2 to 7 weight percent of boria; from 0.5 to 4 weight percent of weight zinc oxide; from 8 to 17 weight percent of calcia; from 0.8 to 7 weight percent of phosphorus pentoxide; and from 2 to 9 weight percent of sodium oxide.
