Sialon II ™ & silicon nitride StrikoWestofen Westomat dosing tubes give the best price/performance rate. We manufacture dosing tubes for both Striko and Westomat dosing furnaces.
These dosing tubes offer a superior service life compared to Aluminium Titanate (AlTi) dosing tubes, which means considerably less downtime for manufacturing.
With regards to Sialons, there is substitution of silicon by aluminum with corresponding atomic replacement of nitrogen by oxygen, to satisfy valency requirements. The resulting 'solution' has superior properties to the original pure solvent, syalon, silicon nitride or Si3N4.
Silicon Nitride like ceramics have found extensive use in non-ferrous molten metal handling, particularly aluminum and its alloys, including metal feed tubes for aluminum die casting, burner and immersion heater tubes, injector and degassing for nonferrous metals, thermocouple protection tubes, crucibles and ladles.
