Quick Details
Specifications
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.
