Welcome to Sialon Ceramics
SiAlON ceramics are a specialist class of high-temperature refractory materials, with high strength at ambient and high temperatures, good thermal shock resistance and exceptional resistance to wetting or corrosion by molten non-ferrous metals, compared to other refractory materials such as, for example, alumina.
A typical use is with handling of molten aluminium. They also are exceptionally corrosion resistant and hence are also used in the chemical industry. SiAlONs also have high wear resistance, low thermal expansion and good oxidation resistance up to above ~1000 °C.
Since 1986, we have been producing high quality Sialon products from different grades to the molten aluminium, zinc and other non-ferrous industries.
Silicon Nitride, syalon or Sialon are beta ceramics which are sintered under high temperatures at 1,800 degrees celsius and can be made in almost any shape.
As Sialon ceramics contain approximately 40% of Aluminium Oxide, they have excellent non-wetting properties when in contact with molten aluminium.
Commercial Sialon was introduced by our company in 1986 to replace ceramic coated cast iron thermocouple protection tubes
