CSIR-IMMT/MAT - 04

Production of fused mullite powder from fly-ash

Advantages / Salient Technical Features Application/Uses
• Plasma processing is very fast and efficient. • Refractories for glass and steel industries,
Kiln furniture Spark plug bodies.

Problem being addressed
• Mullite is being imported in huge quantities from Scale of Development
other countries. Fused mullite has superior properties • Lab Scale validation is well established. (Cur-
than commercially available sintered mullite powder rent TRL Level : 04)

Environmental Considerations (if any) Commercialization Status
• Utilization of industrial waste like Fly ash will reduce • Not yet
soil/land pollution thereby giving a positive impact
on environment
Techno-economics
• NA
Major Raw Materials to be Utilized
• Fly ash Calcined alumina
Technology Package
• Basic process flow sheet, Can be demonstrated
IPR Status / Details (India/Abroad)
• NA No IPR
