YUFA Low Sodium Fused Mullite: Applications & Usage Guidelines
YUFA Low Sodium Fused Mullite is produced from high-purity alumina and silica raw materials through high-temperature electric arc fusion. Compared with conventional fused mullite, the low-sodium grade features lower alkali content, higher purity, excellent thermal stability, and outstanding resistance to thermal shock and chemical corrosion, making it an ideal material for demanding refractory and ceramic applications.
Typical Applications
1. High-Performance Refractory Materials
Low sodium fused mullite is widely used in:
Ladle linings
Tundish refractories
Kiln furniture
Burner blocks
Glass furnace refractories
Cement rotary kiln components
Its excellent refractoriness and low impurity content help improve service life under high-temperature operating conditions.
2. Advanced Ceramic Industry
It is suitable for:
Structural ceramics
Technical ceramics
Electronic ceramics
Wear-resistant ceramic components
The low alkali content helps minimize impurities, contributing to improved mechanical strength and dimensional stability after sintering.
3. Investment Casting
Low sodium fused mullite is an excellent aggregate for investment casting shell production, offering:
High refractoriness
Good thermal shock resistance
Low thermal expansion
Smooth casting surface finish
4. Precision Kiln Furniture
It is widely applied in kiln setters, kiln shelves, saggers, and other kiln furniture requiring long service life and excellent dimensional stability.
Usage Guidelines
Select the appropriate particle size according to your production process and product requirements.
Store the material in a dry environment to prevent moisture absorption and contamination.
Mix thoroughly with binders and other raw materials to ensure consistent performance.
Avoid introducing excessive impurities during processing, as they may reduce high-temperature performance.
Conduct laboratory trials before large-scale production to optimize formulation and firing conditions.
