BERYL AS A CONSTITUENT IN HIGH TENSION INSULATOR PORCELAIN [PDF]

Journal of the American Ceramic Society, 1922
ABSTRACT Two series, one of 9 bodies and one of 6, were prepared, in which flint and feldspar were partially replaced, weight for weight, by beryl. Bars and discs were fired to cone 8 3/4, to 10, or to 10 3/4 and tested for shrinkage, transverse strength, impact strength, heat resistance ...

Study on Thermal/Moisture Expansion Stress of a Drop-Out Fuse Insulator

Journal of Applied Science and Engineering
Drop-out fuses are widely used electrical devices, and their reliability directly affects the safety of power supply systems. Porcelain insulators, as a critical component, are prone to cracking, which significantly disrupts the order of power production.

The effect of kaolin and silica variation on the properties of porcelain insulators

, 2019
Clay, Al2O3, feldspar and silica have been used to produce shackle-type porcelain insulators using slip casting method. The amounts of silica and kaolin were varied from 10 to 30 wt. % while keeping the amounts of other constituents constant. The samples

Porcelain and other Ceramic Insulating Materials [PDF]

Nature, 1944
THE pottery industry is almost virgin territory for the worker in applied science. Despite the trails blazed by J. W. Mellor in Great Britain and H. Seger in Germany, there are still wide tracts quite unexplored. There is still no institution of university status in Great Britain offering a full-time course in ceramics, and the number of qualified ...
