Product Description
Lanthanum Oxide as Sintering Additive for Advanced Electronic Ceramics
Product Overview
This high-quality lanthanum oxide powder is designed as a critical sintering functional additive for advanced electronic ceramic systems, including dielectric ceramics, piezoelectric ceramics and ceramic capacitor materials. Doped La₂O₃ promotes densification at lower sintering temperature, optimises grain boundary structure and improves dielectric strength, insulation performance and ageing resistance of ceramic bodies. It effectively suppresses abnormal grain growth, helping manufacturers reduce firing energy consumption and lower product reject rate. Suitable for both lab formulation development and mass MLCC, piezoelectric component production, our lanthanum oxide undergoes strict particle size grading and impurity control to avoid negative impacts on electrical parameters. Each batch comes with full COA and PSD data for your quality traceability.
Key Features
- Acts as sintering aid and grain growth regulator for ceramic matrix
- Custom particle size to match dry pressing / tape casting processes
- Low alkali impurity level for electronic grade
Particle Size Distribution

Applications
Functional sintering additive for MLCC dielectric ceramics, piezoelectric ceramics, ceramic substrate, electronic ceramic components.
