PARÂMETROS DO PRODUTO
Descrição
Corundum-Mullite Dental Sintering Tray
The Corundum-Mullite Dental Sintering Tray is made of high-purity corundum (Al₂O₃) and mullite composite refractory material, refined through high-pressure molding and high-temperature sintering. It is specifically designed for the sintering of zirconia dentures, all-ceramic crowns, dental bridges, and other dental ceramic materials.
The product features high purity, high temperature resistance, resistência ao choque térmico, deformation resistance, wear resistance, and excellent chemical stability. It can be used long-term in dental sintering furnaces, high-temperature muffle furnaces, and laboratory sintering equipment. With its stable material properties and uniform heating effect, it effectively ensures the dimensional stability and product quality of dentures during sintering, making it a commonly used high-temperature sintering support container in dental laboratories and denture processing centers.
Recursos do produto
- High-purity corundum-mullite multiphase material
Utilizing a high-purity corundum (α-Al₂O₃) and mullite (3Al₂O₃·2SiO₂) multiphase formula, with Al₂O₃ content of 87.66% and SiO₂ content of 11.69%. The high alumina content ensures excellent high-temperature performance and chemical stability, while the multiphase structure retains good thermal shock resistance.
- Extremely low impurity content, non-contaminating dental materials
Extremely low impurity content: Fe₂O₃ 0.15%, CaO 0.12%, TiO₂ 0.07%, K₂O 0.08%, Na₂O 0.14%, MgO <0.01%, loss on ignition <0.05%. During high-temperature use, it does not shed slag, powder, or introduce foreign impurities, ensuring the purity and color stability of dental restorations (such as zirconia crowns) and does not affect the biocompatibility of the material.
- Excellent Thermal Shock Resistance
The mullite phase endows the sagger with excellent thermal shock resistance, adapting to the cyclical processes of frequent temperature rises and falls in dental sintering furnaces. It does not crack or peel under rapid heating and cooling conditions, extending the sagger’s service life.
- Good High-Temperature Resistance and Dimensional Stability
It can be used stably for a long time at dental sintering temperatures (typically 1500-1600℃). Its coefficient of thermal expansion matches well with dental zirconia materials, ensuring that the sagger does not deform during sintering.
- Smooth Surface and Smooth Contact Surface with Workpiece
The smooth and flat surface ensures a smooth contact surface with the dental restoration, reducing the risk of mechanical damage and contamination to the crown surface.

Perguntas frequentes (Perguntas frequentes)
- What materials are primarily used in dental furnace corundum mullite saggers?
Primarily used for the high-temperature sintering of zirconia dentures, all-ceramic crowns, bridges, dental ceramics, and other oral restorative materials, meeting the sintering needs of dental laboratories and denture processing centers.
- What are the advantages of corundum mullite saggers?
The product features high alumina content, high temperature resistance, resistência ao choque térmico, deformation resistance, wear resistance, and excellent chemical stability. This ensures uniform heating during the sintering process, reduces material contamination, and improves the sintering quality of restorations.
- Why choose high-purity materials for sagger making?
High-purity corundum mullite has low impurity content and is less likely to release contaminants at high temperatures, avoiding impacts on the color, strength, and sintering effect of zirconia dentures, thus improving product consistency.
- How to extend the service life of saggers?
It is recommended to use slow heating and cooling according to the sintering process, avoiding rapid heating and cooling; regularly cleaning residues from the sagger surface; and avoiding mechanical impact and localized overload can effectively extend the service life.
- Does the company support customization of different specifications?
Sim. We can customize corundum mullite saggers of different specifications, shapes, and structures according to customer-provided drawings, dimensions, or dental sintering furnace models to meet the matching needs of different sintering processes and equipment.
