· HoWO3

Holmium tungstate (HoWO₄) is a rare-earth ceramic compound combining holmium oxide with tungsten trioxide, belonging to the family of rare-earth tungstates. This material is primarily investigated for photocatalytic and luminescent applications in research settings, with potential utility in optical and radiation-detection contexts due to holmium's unique spectroscopic properties. While not yet widely deployed in mainstream industrial production, HoWO₄ represents an emerging functional ceramic of interest for environments requiring combined thermal stability, optical activity, and chemical inertness.
