Abstract
Disclosed are methods to produce Thermal Barrier Coating (TBC) products using materials recycled from TBC waste. These methods include ways to produce zirconium and rare earth chemicals and raw materials appropriate for producing TBC materials.
Claims17
A method for recovery of thermal barrier coating materials from waste comprising:
- collecting and classifying TBC waste materials to determine chemical composition and impurity levels;
- processing the TBC waste to convert it to a fine powder;
- reacting the fine powder to form a soluble zirconium- and rare earth-containing material;
- and
- collecting the soluble zirconium and rare earth containing materials, including recycled zirconium and rare earth materials, which consist essentially of precursor materials suitable for use in producing TBC feedstock materials.
