What is zirconium hydroxide powder used for?
Zirconium hydroxide powder Zr(OH)4 main applicationsIt is an amorphous white powder with high specific surface area and abundant surface hydroxyl groups. Its largest role is as a precursor for zirconia and other zirconium chemicals, and it is also widely used as adsorbent, catalyst raw material and functional filler.
Precursor for high‑purity zirconia powder (most important use)
When calcined at 500–600 °C, it decomposes into nano‑zirconia. It is used to produce 3Y/5Y yttria‑stabilized zirconia, dental ceramics, structural wear‑resistant ceramics, refractory materials, thermal barrier coatings and ceramic target materials. It can also synthesize various zirconium salts such as zirconium oxychloride, zirconium sulfate and zirconium acetate.

Catalyst & catalyst support
It is the starting material for solid‑acid catalysts (sulfated zirconia). Used in petroleum cracking, isomerization, organic synthesis, automotive three‑way catalysts and industrial denitrification/VOC removal. It can carry noble metals to form high‑stability catalytic systems.
Water‑treatment adsorbent (environmental protection)
Selectively adsorbs fluoride, phosphate, arsenic, heavy metals (lead, cadmium, chromium) and radioactive ions. Applied in drinking water defluoridation, electroplating wastewater and groundwater remediation. It can also serve as deodorant and gas‑purification medium.
New energy & electronic materials
Used for surface coating and doping of lithium‑ion battery cathode materials (NCM, LFP) to improve cycle stability. It is also an additive for MLCC, oxygen sensors, solid oxide fuel cell electrolytes and semiconductor dielectric thin‑film precursors.
Pigments, polymers and light industry
Raw material for zircon‑based high‑temperature ceramic pigments (praseodymium‑zircon yellow, vanadium‑zircon blue, zircon iron red) for tiles and glass glazes.
Flame‑retardant and weather‑resistant filler for plastics, rubber and coatings.
Tanning agent intermediate in leather industry and analytical reagent in laboratories.
Biomedical & daily chemicals
Calcined into biocompatible zirconia for dental crowns and orthopedic implants. It can be used as mild UV‑reflecting raw material in sunscreen formulations.
