What your process engineer actually checks
What your process engineer actually checks
Functional, not structural, data
8Y is chosen for ionic conductivity — σ·T = 17 S·cm⁻¹·K at 800 °C — and >99% density, not for bending strength. We ship the datasheet so you qualify it against the property that matters for your cell.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. 8Y is solid-state sintered, and shrinkage is compensated in build prep so thin electrolyte geometries land on dimension.

About this product
Zirconia 8Y 3D Printing Paste is a 3DCeram 8 mol% yttria-stabilized zirconia paste for the Ceramaker laser-SLA platform — an oxygen-ion conductor developed for solid-oxide fuel cells and electrochemical parts.
Why engineers choose this paste
Fully-stabilized zirconia — used for its ionic conductivity, not its structural strength.
Oxygen-ion conductor
σ = 17 S·cm⁻¹·K at 800 °C — the standard electrolyte material for solid-oxide fuel cells (SOFC).
Stable at high temperature
Fully-stabilized cubic phase stays dimensionally and chemically stable through fuel-cell operating temperatures.
Thermal insulator
Low thermal conductivity suits thermal-barrier and heat-management roles.
Complex SLA geometry
Print thin electrolyte layers and channelled geometries not practical by pressing.
Print → debind → sinter
Ceramic stereolithography on the 3DCeram Ceramaker platform. The green part is larger than the finished part — shrinkage is compensated in build preparation.
Step 01
Laser SLA print
The ceramic-loaded paste is cured layer-by-layer on a 3DCeram Ceramaker laser-SLA machine into a green part.
Step 02
Debinding
The organic binder is removed in a controlled thermal cycle, leaving a fragile ceramic-only brown part.
Step 03
Sintering
Sintered to >99% dense 8Y zirconia (5.79 g/cc, ~0.73 µm grain) with stable oxygen-ion conductivity.
Typical applications
Electrochemical and high-temperature energy applications.
Solid-oxide fuel cells
Electrolyte layers and cell components
High-temperature parts
Electrochemical and energy hardware

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is Zirconia 8Y and how is it different from 3Y?
Zirconia 8Y is fully-stabilized zirconia (8 mol% yttria), whereas 3Y is partially-stabilized. The extra yttria locks in the cubic phase, which makes 8Y an excellent oxygen-ion conductor but mechanically weaker than 3Y. You choose 8Y for its ionic conductivity in fuel cells and electrochemical devices, and 3Y when you need structural strength. They are not interchangeable.
What is 8Y zirconia used for?
The main application is the electrolyte layer of solid-oxide fuel cells (SOFC), where oxygen-ion conductivity at high temperature is the whole point. It is also used in oxygen sensors and other electrochemical and high-temperature components. Ceramic SLA lets you print thin, channelled or complex electrolyte geometries that are hard to make by conventional pressing.
How is the ionic conductivity specified?
The datasheet gives σ·T = 17 S·cm⁻¹·K at 800 °C and σ·T = 3 S·cm⁻¹·K at 600 °C — conductivity rises strongly with temperature, which is why SOFCs run hot. If your cell design targets a particular operating temperature and conductivity, send the requirement and a materials engineer will confirm against the 8Y data.
Why does the printed part shrink during processing?
Like all ceramic AM, 8Y prints as an oversized green part; the binder burns out in debinding and the particles fuse in sintering, so the part shrinks to final size. Shrinkage is predictable and compensated in build preparation. For thin electrolyte layers this control matters, and we supply the parameters that make it repeatable.
Which printer runs this paste?
8Y zirconia paste runs on 3DCeram Ceramaker laser-SLA machines (C900 FLEX and the Cxxx family). It is not an FFF filament. If you need the machine as well as the material, we quote the printer, paste and post-processing route together — ask for a system quote.
Can I get a sample to qualify it for my cell?
Yes. Because 8Y is bought for a specific functional target, we routinely ship a sample or small batch so you can validate density and conductivity on your own setup before a production order. Talk to a materials engineer to scope the trial — NDA standard.
