                      sol–gel process arepromising building blocks for various
                      photonic applications considered forheat management and
                      energy systems, including highly effi cient refl
                      ectivethermal barrier coatings and absorbers/emitters used
                      in thermophotovoltaicsystems. As previously shown, pure
                      zirconia microparticles deteriorate atworking temperatures
                      of ≥1000 °C. While the addition of yttrium as a dopanthas
                      been shown to improve their phase stability, pronounced
                      grain growthat temperatures of ≥1000 °C compromises the
                      photonic structure of theassembled microspheres. Here, a new
                      approach for the fabrication of highlystable ceramic
                      microparticles by doping with lanthanum, gadolinium, and
                      acombination of those with yttrium is introduced. The
                      morphological changesof the particles are monitored by
                      scanning electron microscopy, ex situX-ray diffraction
                      (XRD), and in situ high-energy XRD as a function of
                      dopantconcentration up to 1500 °C. While the addition of
                      lanthanum or gadoliniumhas a strong grain growth attenuating
                      effect, it alone is insuffi cient to avoida destructive
                      tetragonal-to-monoclinic phase transformation occurring
                      afterheating to >850 °C. However, combining lanthanum or
                      gadolinium withyttrium leads to particles with both effi
                      cient phase stabilization and attenuatedgrain growth. Thus,
                      ceramic microspheres are yielded that remainextremely stable
