Sialon, The combination of silicon nitride and aluminum oxide produces a material with the excellent strength, hardness, fracture toughness and low thermal expansion of silicon nitride, enhanced by corrosion resistance, good high temperature strength and oxidation resistance imparted by the aluminum oxide.

 

Sialon silicon nitirde, a fine grain nonporous technical grade engineering material, is a silicon nitride ceramic with a small percentage of aluminum oxide added.

 

Sialon silicon nitride is outstanding in nonferrous metal contact. It is highly thermal shock resistant, strong, and is not wet or corroded by aluminum, brass, bronze, and other common industrial metals.


sialon Riser Tube stalk are available with plain ends, grooved ends for assembly with metal flanges, or with integral collars for the optimum in strength and reliability. Tooling available for most LP die casting machines.

 

Because of unique properties to withstand thermal shock, erosion, and corrosive attack, coupled with its impervious and non wetting advantages, Sialon riser tube and silicon nitride riser tube stalks are long lasting and mainly maintenance free.

 

This new isostatically pressed class of advanced ceramics shows a major improvement with regards to the impact fracture toughness of Si3N4 / Syalon.

 

STA sialon riser tube or riser stalk have excellent non-wetting properties and a smooth surface are also important new features. Sialon silicon nitride tube can now be manufactured in nearly all shapes.

 

Sialon riser tube or riser stalk are an alloy of silicon nitride and aluminum oxide. The combined properties of silicon nitride (high strength, hardness, fracture toughness, and low thermal expansion) and aluminum oxide (corrosion resistance, chemically inert, high temperature capabilities, and oxidation resistance) is very good performance.
