Abstract
A robust coated core comprising a composite with a fused or sintered coating.
Claims11
A composite structure comprising:
- (i) a substantially spherical soda lime glass core bead with an outer surface and a diameter of from about 500 to about 2000 micrometers;
- and
- (ii) at least one continuous fused interphase layer covering the outer surface of the core bead, wherein the at least one continuous fused interphase layer consists essentially of fused soda lime glass particulates and an inorganic central atom derived from an interfacial modifier and wherein the core bead does not melt.
A composite structure comprising:
- (i) a substantially spherical soda lime glass core bead with an outer surface and a diameter of from about 500 to about 2000 micrometers;
- and
- (ii) at least one continuous fused interphase layer covering the outer surface of the core bead, wherein the at least one fused interphase layer
- consisting essentially of a plurality of soda lime glass particulates, each particulate having a longest dimension of 10 micrometers or less, and an interfacial modifier having a central atom and two or more organic substituents;
- and heating the resulting coated bead to melt the soda lime glass particulates, followed by cooling to form the at least one fused layer and wherein the core bead does not melt.

- and
- (ii) at least one continuous fused interphase layer covering the outer surface of the core bead, wherein the at least one fused interphase layer is formed by:
- coating the outer surface of the core bead with a mixture consisting of a plurality of soda lime glass particulates, each particulate having a longest dimension of 10 micrometers or 20 less, and an interfacial modifier having a central atom and two or more organic substituents;
- and heating the resulting coated bead to melt the soda lime glass particulates, followed by cooling to form the at least one fused layer and wherein the core bead does not melt.
