i-STAR Ferro Silicon Nitride
i-STAR FERRO SILICON NITRIDE is a new material designed for refractory applications, primarily used for Tap Hole clay mud refractory manufacturing. It is produced by nitriding a mixture of high-grade metallic alloys.
Synthesized in special reactors under high pressure and at a temperature of about 2000°C, it possesses a unique combination of chemical properties and is grey-white in colour.
Benefits of i-STAR FERRO SILICON NITRIDE for Refractories:
- Increases the strength and wear resistance of the Tap Hole clay mud refractory at high temperatures.
- Enhances thermal stability and resistance to oxidation.
- Reduces the thermal-expansion coefficient while increasing thermal conductivity.
- Provides more resistance to abrasion by hot metal and slag.
- Does not shrink on repeated heating.
- Increases erosion resistance against liquid iron, thus increasing the holding time of the blast furnace.
