Syalon 201 is an advanced silicon nitride (Si₃N₄) ceramic offering outstanding mechanical properties up to 1350°C.
Syalon 201, a silicon nitride based advanced ceramic, is a specially formulated grade based on the β-sialon phase found in Syalon 101 but with a crystalline intergranular phase of yttrium aluminium garnet (YAG). This enables Syalon 201 to exhibit significant retention of strength at high temperatures up to 1350°C.
Syalon 201 is an outstanding engineering grade material which is characterised by excellent high temperature strength and hardness. It has found use in molten metal handling applications where the use of Syalon 101 is limited due to its reduction in strength above about 1000°C.
The table below lists typical thermomechanical and electrical properties for Syalon 201.
