Quick Details
Specifications
Silicon Nitride Riser Tube
The features of silicon nitride riser tube are the same with Aluminium titanate,but the density and strength of silicon nitride are higher,so the service life is 5--20 times longer than other ceramic riser tube that the replacement is greatly reduced.
Widely applied in aluminium alloys casting,non-ferrous metal metallurgy etc.
