Aluminum Oxide/ Titanium Oxide/ Cerium Oxide as Spray Grade
Aluminium Oxide – Titanium Oxide – Cerium Oxide spray-grade powder is a tri-oxide thermal spray feedstock engineered for demanding wear-, corrosion-, and dielectric-critical coating applications. Building on the well-established Al2O3-TiO2 thermal spray platform, a controlled cerium oxide addition densifies the deposited coating and sharpens its corrosion resistance without sacrificing the hardness and dielectric strength that make alumina-titania blends an industry standard. Supplied as a free-flowing, 40-60 micron composite powder at greater than 99.8% purity, it is optimised for consistent melting and splat formation in atmospheric plasma spray (APS) and HVOF guns. Aerospace, automotive, energy, and marine engineers specify this blend where a hard, wear-resistant, electrically insulating coating must also stand up to aggressive, chloride-rich or high-humidity service environments. Blend ratios are fully customizable, letting the coating be tuned along the hardness-toughness-corrosion resistance spectrum for a specific component and duty cycle.
Alumina–Titania–Ceria (Al₂O₃–TiO₂–CeO₂) is a mechanically blended ceramic composite rather than a single chemical compound, with the exact oxide ratio tailored to the application. Al₂O₃ provides high hardness, abrasion resistance, and electrical insulation; TiO₂ improves plasma melt fluidity, splat bonding, and toughness; while small CeO₂ additions promote grain refinement and densification. As a spray-grade powder, the blend is designed for thermal-spray deposition rather than sputtering, with atmospheric plasma spraying (APS) and HVOF producing dense, adherent coatings with controlled thickness and porosity. CeO₂ can reduce coating porosity, promote stable α-Al₂O₃ formation, and improve corrosion resistance. These coatings are used for wear-resistant, corrosion-resistant, and electrically insulating protection of metallic components in demanding environments.
Answer: This composite material is used in various industries, including aerospace, automotive, energy, marine, and oil & gas, due to its versatility in high-performance coatings, such as thermal barrier coatings, catalyst supports, and wear-resistant layers.
Answer: It serves as a spray material for uniform coating on metal surfaces. This composite material improves thermal insulation, abrasion resistance, corrosion protection, and catalytic properties, making it ideal for use in severe environments and high-performance applications.
Answer: This material is ideal for components exposed to extreme conditions, such as turbine blades, engine parts, industrial machinery, cutting tools, and gas turbine components. It also benefits offshore rigs, subsea equipment, and energy storage devices.
Answer: Aluminum, titanium, and cerium oxides have high boiling and melting points, making them suitable for refractory material and catalysis at high temperatures.

Grade / Form
Typical Purity
Key Features / Uses
97/2/1 (Al2O3/TiO2/CeO2)
> 99.5%
Near-pure alumina base with minor toughening and densification; highest hardness and dielectric strength, lowest fracture toughness of the series
87/10/3 blend
> 99.5%
Analogous to the industry-standard 87/13 Al2O3-TiO2 powder with CeO2 substituted for part of the TiO2; balanced hardness/toughness with denser, less porous coating microstructure
80/15/5 blend
> 99%
Matches the higher CeO2 loading (5 wt%) validated in plasma-spray corrosion studies for maximum void-filling, grain refinement, and pitting-corrosion resistance in marine/offshore duty
60/35/5 blend
> 99%
Higher-TiO2 formulation analogous to 60/40 Al2O3-TiO2 for maximum toughness and machinability, with CeO2 added to control porosity; used where coating spallation/cracking risk is the primary concern
Fine-cut, any ratio (-45+15 micron)
> 99.8%
Narrower, finer particle size distribution for HVOF and suspension plasma spray, producing thinner, smoother, lower-porosity coatings
