Sobre IBD

Opracowano skład szkła borokrzemowego domieszkowanego fluorkiem krzemu sodu, który był bardziej wyrafinowany, wolny od ziaren, pęcherzyków i splotów. Dodatek związku fluorku przyspieszył topienie szkła, ale zmniejszył jego lepkość i napięcie powierzchniowe. Wprowadzono wiele zmian w standardowym składzie szkła borokrzemowego (7740) w celu opracowania nowego składu, który można było topić w warunkach ekonomicznie dostępnych. Piec elektryczny z systemem mieszania był bardzo drogi, co uniemożliwiało Pakistanowi opracowanie tak kosztownego szkła. W związku z tym do topienia tych rodzajów szkła zamiast pieca elektrycznego zastosowano piec gazowy bez systemu mieszania, pracujący w stosunkowo niższej temperaturze. Szkło to zostało opracowane po raz pierwszy w Pakistanie w skali laboratoryjnej, przy użyciu zasobów naszego kraju i dostępnych urządzeń.
