Silicate technological know-how, quantity VIII: commercial Glass: Glazes and Enamels provides a targeted dialogue relating to glass fusion furnace building in addition to development for the potency of many of the platforms interested by glass engineering. The examine papers provided during this quantity are constrained within the dialogue of the actual and chemical response phenomena which take place in glass tank furnace and electrical furnaces of different shapes.
The booklet includes of six significant chapters the place a few chapters extra divide into elements. many of the subject matters coated during this publication comprise vital advancements within the reactions of a few batches, homogenization and fining of uncooked melts, and the habit of the glass melts in occasions the place refractories come into touch with the molten fabric.
This quantity will function a wealthy resource of data to scholars and researchers within the glass engineering, production, and expertise.

Over the temperature range from 900° to 1400°C. The solubility of C 0 2 in such melts rapidly decreases with increasing temperatures as would be expected for the C 0 2 solubility, but increases with increasing alkalinity ( N a 2 0 concentration). 0% C 0 2 . Thereaction C 0 2 + Ο 2 - -* C O 2 -s h o w s a direct proportionality to the O 2 -i o n activity, and this increases by four orders of magnitude in the experimental range. There is a remarkable similarity between these facts and the conditions observed by Pearce in borate glasses, 57 and for the solubility of H 2 0 in alkaline silicate melts.
