Thermal Analysis and Performance Evaluation
To validate the superior performance of BeO crucibles, Shenzhen Great Ceramic conducts comprehensive thermal and mechanical testing during product development.
Thermal Conductivity Evaluation：BeO crucibles demonstrate consistent heat distribution across the entire crucible body, reducing hot spots and extending service life. Infrared thermal imaging confirms a temperature deviation under ±3°C, even under rapid heating cycles.
Thermal Shock Resistance：BeO crucibles maintain structural integrity after repeated exposure between room temperature and 1600°C, without cracking or deformation — significantly outperforming alumina by over 40%.
Mechanical Strength & Dimensional Stability：Our BeO ceramics show a flexural strength exceeding 250 MPa and low thermal expansion (7.5×10⁻⁶/K), ensuring dimensional stability under long-term heating.
Vacuum and Purity Testing：BeO crucibles are ideal for high vacuum and ultra-clean environments. Residual gas analysis (RGA) confirms negligible outgassing, suitable for semiconductor epitaxy and sputtering applications.
