Superior Temperature Resistance
Your experiments require consistent heat distribution. Our crucibles maintain structural stability at temperatures up to 2200°C without warping or cracking.
Chemical Inertness
You can trust these crucibles with reactive materials. Zirconium's excellent chemical resistance prevents contamination of your samples during high-temperature processes.
Extended Durability
Each crucible provides over 100 heating cycles, making them cost-effective for regular laboratory use. You reduce replacement frequency while maintaining consistent performance.
Precise Thermal Conductivity
The controlled wall thickness ensures uniform heat transfer, giving you reliable and reproducible results every time.
Research Laboratories
Perfect for materials science research, metallurgical studies, and advanced chemistry experiments requiring extreme temperatures.
Educational Institutions
Universities and technical colleges use our crucibles for student training and academic research projects.
Industrial Testing Facilities
Quality control laboratories in aerospace, automotive, and electronics industries rely on these crucibles for material testing.
Specialized Applications
We employ advanced manufacturing techniques at our Baoji facility. Our process begins with high-purity zirconium sourcing from certified suppliers. We use precision machining and forming processes to achieve exact specifications.
Each crucible undergoes controlled heating treatment to optimize its microstructure. This process enhances thermal shock resistance and extends service life. Our skilled technicians monitor every production step to ensure consistent quality.
Every batch undergoes comprehensive testing before shipping. We verify chemical composition using advanced spectroscopy methods. Dimensional accuracy is confirmed through precision measurement tools.
Thermal cycling tests simulate real laboratory conditions. We conduct stress testing to ensure each crucible meets our durability standards. Only crucibles passing all quality checkpoints reach our customers.
We respond promptly to inquiries and provide detailed technical information to help you make informed decisions. Our experienced staff understands laboratory requirements and can guide you toward the optimal crucible solution for your specific applications.
