Thermal barrier coatings (TBCs) can enhance the durability and energy efficiency of the hot section components of gas turbines. The most common material used as the ceramic topcoat is 3.4–4.5 mol% yttria-stabilized zirconia (YSZ), applied either by electron beam physical vapor deposition (EB-PVD) or atmospheric plasma spraying (APS). As second-generation thermal barrier oxide materials, rare-earth zirconates (RE2Zr2O7) has higher stability and lower thermal conductivity at a higher temperature, which attracted more and more attention in recent years. In addition to the standard 3.4–4.5 mol% YSZ nanopowder, Grirem Advanced Materials Co., Ltd. can supply a wide range of second-generation rare-earth zirconates (RE2Zr2O7) TBCs nanopowder according to customized requirements.
