发明名称 METHOD OF PRODUCING EFFECTIVE POROUS GLASS SHAPES
摘要 Porous glass shapes with effective pores are produced by a method which also reduces the frequency of breakage of the glass shapes. The method includes: producing a plurality of the glass shapes, depositing a fluid chemical treatment with one or more carbonaceous materials on a substantial portion of the surfaces of the glass shapes, heat treating the glass shapes to phase separate components of the glass, leaching the phase separated glass shapes to remove leachable components to produce pores in the glass shapes, and removing any residual carbonaceous material. The various forms of glass shapes include particles, platelets, flakes, beads, fibers both solid and hollow, tubes and capillaries, which are essentially free of carbonaceous material.
