example 1

[0106] A 52% solids slurry was prepared by combining 35.00 g of titanium dioxide, 11.00 g of silicon dioxide, 59.20 g of barium carbonate, 10.71 g of calcium carbonate, and 3.81 g of sodium borate while mixing. Prepare powder. 54g of deionized water was added to 96.07g of the powder to form a 64% solids slurry. The slurry was placed in a ceramic grinding jar filled with zirconia media and ground for 4 days. An additional 10 g of deionized water was added on the third day of milling and 25 g of deionized water was added on the fourth day for a total of 89 g of water to obtain a slurry with 52% solids. Then 1.92 g of surfactant and 8.96 g of D sodium silicate liquid binder (PQ Corporation, Berwyn, PA) were added to the slurry.

[0107] The resulting composition was then manually spread with a squeegee on a surface with a 2.4 x 10 7 cc tapered micro-mold on the tool to fill the mold. The filled molds were placed in an oven at 204.8°F (96°C) and dried for 3 hours. The molded ...

Abstract

The present invention provides a method for preparing inorganic metal oxide spheres, the method comprising: exposing hardened molded particles comprising a glass precursor composition to a temperature sufficient to convert the molded particles into molten glass; and cooling the molten glass to form inorganic metal oxide spheres.

Description

Background technique [0001] The present invention relates to the formation of inorganic metal oxide spheres from molded particles. [0002] Various methods are currently used to prepare glass beads, also known as glass microspheres. These methods often require repeated steps of comminution and classification of particulate material in an effort to obtain glass beads with a relatively narrow particle size distribution. Some methods of making glass beads include generating a granular feed material and then converting the granular feed material to glass by melting. The particulate feed material can be formed by crushing glass particles (or components that form glass when heated at a sufficiently high temperature) and, for example, by grinding to volatilize the crushed particles with a volatilization agent such as water. Sexual liquid is fully blended. Binders such as dextrin or starch are sometimes added to bind the ground particulate raw materials together. The ground materi...
