CO induces the reduction of Mo in the glass liquid to molybdenum carbide to form glass defects in the hybrid furnace
In this work, a ceramic platinum continuous melting optical glass furnace containing oxygen combustion was taken as an example to analyze the causes of a unique glass defect. It was finally determined that the defect in the glass was composed of the top condensate, the brick skeleton, and the Mo2C generated in the glass liquid. It was determined that the monoclinic Al2O3 and ZrO2 phase in the brick desorbed the surface hydroxyl and water molecules under the high temperature environment inside the furnace, forming Lewis acid sites with the ability to adsorb electrons. CO was adsorbed on the surface of Al2O3 and ZrO2 by Lewis acid sites and fell into the glass liquid with the top condensate and the brick skeleton.CO then reduced Mo ions in the glass melt to form Mo2C, causing the formation of the defects in the glass.
期刊介绍：
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
