Product Description
Product Description
High Thermal Conductivity Corundum mullite Saggar for Uniform Heating
Our company's corundum-mullite saggers are high-quality refractory containers specifically designed for high-temperature sintering, heat treatment, and calcination processes. They are primarily made from electro-fused corundum and high-purity mullite, produced through precise batching, high-pressure forming, and high-temperature firing. The products feature excellent high-temperature resistance, thermal shock resistance, corrosion resistance, and high strength, making them ideal for firing high-end ceramic products such as zirconia, alumina, rare earth materials, and electronic ceramics. They effectively ensure product quality and yield.
Specification
Core Advantages
Exceptional High-Temperature Performance: The corundum-mullite material has a high refractoriness, with a maximum service temperature of up to 1650°C, meeting the requirements of most high-temperature firing processes.
Outstanding Thermal Shock Resistance: The material has a low thermal expansion coefficient, preventing cracking during rapid temperature changes. It can withstand multiple thermal cycles, effectively extending the sagger's service life.
Excellent Chemical Corrosion Resistance: It exhibits strong resistance to alkaline oxides (such as calcium oxide and magnesium oxide) and slag, effectively preventing reactions between the sintered material and the sagger and avoiding product contamination.
High Mechanical Strength: The sagger maintains high strength and hardness at elevated temperatures. It is highly resistant to compression and deformation, ensuring stable support for products during the firing process.
Diverse Size Customization: We offer customization services for various sizes, shapes, and thicknesses based on customer specifications, providing a perfect fit for your kiln and products.
Eco-friendly and Energy-Saving: The lightweight design results in low heat storage and good thermal conductivity, which helps to improve kiln thermal efficiency and reduce energy consumption.
