◈ Good Compressive Strength: Room temperature compressive strength meets specified minimums for each grade.
◈ Good Refiring Stability: Rate of change of the refiring line is controlled for each grade.
◈ Low Thermal Conductivity: Low thermal conductivity (≤1.4 W/m·K at average temperature 800°C).
◈ High Operating Temperature: Maximum operating temperature ranges from ≥1600°C to ≥1800°C depending on grade.
High-temperature industrial furnaces and equipment.
