AN ELECTRIC VITREOUS ENAMELING OVEN 1 [PDF]

open access: yesJournal of the American Ceramic Society, 1921
ABSTRACT Comparison with older types of furnaces.—In marked contrast with the oil, coal and gas furnaces the electric furnace eliminates damaged ware and makes possible the utilization of the entire heating space. Its initial cost and the fuel costs are double those of the older types but it admits 25 per cent increase in weight per ...

Vitreous and Crystalline Phosphates : elaboration and electrical properties [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Interest in mixed metals titanium phosphates, both in glass and crystalline forms, for their properties as ionic conductors or non-linear optical materials, has led to large number of studies of these materials [1-3]. Our investigation of Na2O – Li2O – CaO – TiO2 – P2O5 system led to the discovery of NaxLiyCazTit(PO4)3 solid solutions which exist in ...

Vitreous composition modification after transpalpebral electrical stimulation of the eye: Biochemical analysis

open access: yesExperimental Eye Research, 2021
Electrical stimulation (ES) of the eye represents a therapeutic approach in various clinical applications ranging from retinal dystrophies, age-related macular degeneration, retinal artery occlusion and nonarteritic ischemic optic neuropathy. In clinical practice, ES of the eye is mainly performed with a transcorneal or transpalpebral approach.
