Metallurgy
Metallurgical quartz is a high-purity quartz used in iron, steel and ferroalloy production as a slag former (flux) and silicon source. In metallurgical processes, quartz adjusts the viscosity of the slag, helps separate impurities and supplies the silicon in alloys such as ferrosilicon. High-purity quartz (typically SiO₂ 99.8%) delivers consistent chemical behaviour in metallurgical applications.
How to Choose Metallurgical Quartz
The criteria that define metallurgical quartz are clear. SiO₂ purity determines the amount of silicon entering the process and the composition of the slag; higher purity gives a more consistent metallurgical result. Grain size is selected according to the furnace type and charging system; the correct size ensures the quartz reacts properly in the furnace. A low level of unwanted impurities preserves the quality of the final metal or alloy. Thermal stability is important in high-temperature processes.
Recommended Product for Metallurgy
Metallurgical applications use granular quartz in a gradation suited to the furnace and process. We can determine the right grain size together according to your process (slag former, ferroalloy, etc.).
About Metallurgy
What does quartz do in metallurgy?
As a slag former (flux) it adjusts the viscosity of the slag and, in alloys such as ferrosilicon, it supplies the silicon source.
Is quartz used in ferrosilicon production?
Yes, quartz is the primary silicon source in ferrosilicon production.
Does quartz purity affect the metallurgical result?
Yes, high SiO₂ purity determines the amount of silicon entering the process and the consistency of the result.
What grain size is metallurgical quartz?
Granular quartz is used in a gradation suited to the furnace type and charging system.
