PRODUCTION OF MICROSPHERES IN GLASS

1. A method of forming hollow microspheres from particles of glass having dimensions of less than 50 microns by bringing said particles into suspension in a gaseous current, passing said particles through a burner for recovery of the microspheres formed, characterized in that a fluidifying agent is...

Beschreibung
Zusammenfassung:	1. A method of forming hollow microspheres from particles of glass having dimensions of less than 50 microns by bringing said particles into suspension in a gaseous current, passing said particles through a burner for recovery of the microspheres formed, characterized in that a fluidifying agent is mixed with the particles of the glass, the fluidifying agent being an organic compound comprising a polar part having an affinity for the glass and a non-polar part.
