We also can produce various Silicon nitride ceramic products.We use
Gas pressure sintered technology.We call it GPSSN.GPSSN is sintered
by high temperature after iso-pressing of silicon nitride powder
with additives.
The nitrogen pressure (<*0 Mpa) during sintering will stop the
dissociation of silicon nitride and guarantee the full sintering at
high temperature that make the highest density and lowest
porosity.
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 ****0 times longer than other
ceramic riser tube that the replacement is greatly reduced.
Widely applied in aluminium alloys casting,non-ferrous metal
metallurgy etc.
