The Use of Molybdenum Electrode in the Glass Industry


Out of all the refractory metals, Molybdenum is the most used metal. When manufactured into an alloy, it is extremely resistant against high temperatures and creeps, making it extremely corrosion resistant. With uses that range from electric furnace heating elements, spray metallizing, rocket skirts, cones, heat shields, zinc refining pumps, switch electrodes and tools for metalworking – Molybdenum is also highly commended for its use as a high performance electrode for melting glass in the glass manufacturing industry.

Molybdenum electrode can be used for glass industry, and work in the glass solution with the temperature of 1300℃. Molybdenum electrode is used as electro-heat equipment of the glass fiber kiln. It is an important part in rare earth industry. Its density is more than or equal to 10g/m3, and its purity can reach 99.5%.


The glass industry is a major consumer of metallic molybdenum electrodes, with experience demonstrating molybdenum to be a superior material for electric heating during smelting of glass and basalt. Used in the manufacturing process from broad-spectrum glass, glass fibre and optical glass to insulation materials –glass melting electrodes must be able to tolerate extremely aggressive glass melts with intensely high temperatures.


Electrical heating and boosting with molybdenum glass melting electrodes have set a new standard within the industry for efficiency in glass production:

-  homogenous temperatures in the glass tank
-  improved glass quality
-  increased productivity
-  higher flexibility regarding tonnage output
-  environmentally-friendly production with reduced CO2 emissions


Wherever operating temperatures and chemical requirements exceed the limits of conventional materials such as iron, copper, or nickel - molybdenum stands out with unique properties:

-  high material strength at high temperatures 
-  good electrical conductivity 
-  excellent corrosion-resistance against molten glass
