Refractory Powder / Filler
1400–1800°C
Main applications
refractory powder and filler that stop heat leakage at source
Key Features
Specialised for fine-gap filling
Powdered refractory material — filling joints and gaps invisible to the eye
Highly refractory powder
Alumina, silica, magnesia and others — sintering stably above 1600°C
Raw material for refractories and composites
Filler for castables, mortars and coatings — a key ingredient in improving refractory properties
Seals refractory lining joints
Refractory filling of joints between bricks and formed parts — closing off heat leakage paths completely
A range of particle sizes and compositions
Particle size, alumina content and sintering temperature all selectable — we recommend the specification after consultation

Notes
- ※Particle size distribution directly affects packing density — tell us the location and temperature and we will recommend the grading.
- ※Must be stored dry; absorbed moisture causes clumping, so confirm it is dry before use.
