Title: Preparation of formed glass
Inventor: YANO ATSUSHI
IPC: C03B19/08
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a foamed glass without using carbon and a harmful material such as antimony oxide or arsenous acid by adding boron oxide and/or boric acid as foaming agent to glass. SOLUTION: Boron oxide and/or boric acid are added by 10-50 wt.% as a foaming agent to a waste glass for obtaining a foamed glass by foaming a glass. A heating temp. in the foaming is below or at a softening temp. of the waste glass or a softening temp. of a waste glass added with the foaming agent, e.g. <=800 deg.C. Therefore, energy needed for preparing the foamed glass can be reduced and composing materials of a furnace itself can be made to have a longer life resulting from enhancement of its durability. In practice, the waste glass and the foaming agent are charged in a ball mill of an alumina earthen-ware and then they are mixed for 24 hours after adding an alcohol thereto.  The mixed slurry material is made into a powdery product after drying, and then, the foamed glass is obtained by maintaining temp. at 800 deg.C for one hour after raising temp. by heating the powdery product in an alumina crucible.
