Alumina ceramic crucible support

As a professional manufacturer of custom quartz products, we are committed to providing high-performance and highly stable thermal accessories for industrial customers worldwide. The alumina ceramic crucible support is one of our core products developed based on years of material processing experience. It is specially designed for high-temperature, corrosive and precision heat treatment environments and is widely used in scientific research, metallurgy, semiconductors, chemical engineering and new energy fields.

Avantages du produit

• Outstanding high-temperature resistance: Made of high-purity alumina ceramic (Al₂O₃ content ≥99%), the maximum service temperature can reach 1800℃, and the long-term service temperature is 1600℃. It still maintains excellent mechanical strength and dimensional stability at high temperatures.
• Excellente résistance aux chocs thermiques : The combination of low thermal expansion coefficient and high thermal conductivity significantly reduces the risk of cracking caused by sudden temperature changes, making it suitable for rapid temperature rise and fall processes.
• Grande stabilité chimique : It has extremely strong resistance to corrosion by most acids, alkalis and molten metals, and is especially suitable for active material processing and corrosive atmosphere environments.
• Résistance mécanique et résistance à l'usure élevées : The high hardness and wear resistance ensure that the structure remains intact under long-term load-bearing and friction conditions, thus extending the service life.
• Low pollution and high cleanliness: The material is pure, with no precipitation and no contamination of samples, meeting the high-purity process requirements of semiconductors, crystal growth, etc.
• Precise structural design: The bracket structure has been optimized through thermodynamic simulation to ensure uniform heating of the crucible, stable support, and reduced thermal stress concentration.

Principaux domaines d'application

• Industrie des semi-conducteurs et de l'énergie photovoltaïque : Growth of monocrystalline silicon and polycrystalline silicon, wafer processing, sintering of photovoltaic materials.
• Laboratories and research institutions: High-temperature experiments, material synthesis, thermal analysis (TGA/DSC), crystal growth.
• Metallurgy and Metal Processing: Precious metal smelting, alloy preparation, vacuum or atmosphere-protected heat treatment.
• Chemical Engineering and Catalysis: Sintering of catalyst carriers, high-temperature reactions of chemical materials.
• New energy and Battery materials: Sintering of positive and negative electrode materials, solid electrolyte testing.

Quels problèmes pouvons-nous résoudre ?

1. High-temperature deformation and failure: Traditional metal or ordinary ceramic supports tend to soften and deform at long-term high temperatures. Our alumina ceramic supports maintain shape stability at high temperatures, reducing the frequency of equipment downtime and replacement.
2. Contamination and cross-contamination: Insufficient purity of materials may lead to sample contamination. Our high-purity alumina ceramics ensure process cleanliness and are particularly suitable for the preparation of high-purity materials.
3. Risk of thermal shock cracking: Cracking of the support during the heating and cooling process is a common issue. We have significantly enhanced the thermal shock resistance through material proportioning and process optimization, adapting to the harsh process cycles.
4. Customized Demand Matching: Non-standard sizes, special structures or performance requirements are often difficult to meet. We offer one-stop customized services from design to production, precisely matching customers’ equipment and processes.

Customer Case (Anonymous
A certain semiconductor material supplier in Europe: For the growth process of silicon carbide crystals, a large-sized, multi-hole designed alumina scaffold was custom-made. It operated continuously in a hydrogen atmosphere at 1650℃ for over 12 months without deformation or pollution. The customer reported that the product’s lifespan was more than twice that of the original product.
A national-level laboratory in North America requires a micro-bracket for high-temperature thermal analyzers (1800℃), which demands extremely high dimensional accuracy and thermal stability. Through precise grouting molding and processing, we achieve a tolerance of ±0.05mm, fully meeting its ultra-high temperature testing requirements.
A certain new energy battery R&D enterprise in Asia: For the pilot-scale sintering of cathode materials, a multi-layer stacked bracket structure was customized, which increased the output of a single furnace by 30%, and the bracket did not crack during repeated temperature rises and drops, significantly improving the experimental efficiency.
