95% Alumina Ceramic Roller for European Lithium Battery Roller Kilns High Purity Wear Resistant Furnace Roller
2026/06/21
Ceramic Kiln Rollers Powering Europe's Battery Manufacturing Revolution
As Europe accelerates toward its Green Deal targets and gigafactory construction surges across the continent, XQCERA announces its 95% Alumina Ceramic Roller for Lithium Battery Roller Kilns - a critical component for the cathode and anode material sintering processes that underpin Europe's battery supply chain.
The Role of Ceramic Rollers in Battery Manufacturing
Lithium battery electrode materials - NMC, LFP, graphite, and silicon-based anodes - require precisely controlled sintering in roller hearth kilns at temperatures up to 1000C+. The ceramic rollers that support and transport material through these kilns must maintain exceptional dimensional stability, wear resistance, and chemical inertness to ensure consistent product quality. XQCERA's 95% alumina rollers are purpose-engineered for this demanding application.
Why 95% Alumina?
- High Purity: 95% Al2O3 composition with controlled impurity levels prevents contamination of battery materials during sintering
- Exceptional Wear Resistance: Hardness 85-90 HRA ensures long service life in continuous 24/7 kiln operations
- High-Temperature Stability: Maintains mechanical strength and dimensional accuracy at sustained operating temperatures up to 1500C
- Thermal Shock Resistance: Withstands rapid temperature gradients during kiln startup and shutdown cycles
- Corrosion Resistance: Inert to the oxidizing and reducing atmospheres used in electrode material processing
