Detailed Applications
1. Refractory Materials
An important raw material for furnace linings and roofs. It significantly improves high-temperature resistance and thermal efficiency in furnaces and kilns that require stability over extended periods.2. Thermal Insulation
Utilizing low thermal conductivity and lightweight properties to manufacture insulating bricks and boards. Widely used in construction, chemical, and metallurgical fields to reduce heat transfer.3. Catalyst Support
With a high specific surface area and stable chemical properties, these spheres serve as excellent catalyst supports, improving the activity and stability of catalytic reactions.4. Fillers and Adsorbents
Used in chemical and environmental protection sectors to purify gases/liquids or remove harmful substances, supporting cleaner production processes.5. Lightweight Structures
Ideal for aerospace insulation panels and automotive components. They reduce overall weight while maintaining strength, thereby improving equipment operating efficiency.6. High-Temp Insulation Fillers
Functions as ultra-high-temperature insulation filler and lightweight aggregate for refractory concrete and castables, providing effective protection in extreme heat environments.
