Silicon Nitride Ceramic Protection Tube for Molten Aluminum

The prime features of  Si3N4 Silicon Nitride Ceramic

1. Extraordinary thermal shock, it can withstand up to1000ºC
2. It’s easier to do precise machining, the tolerance can be 0.001mm
3. Chemical corrosion resistance under high temperature, except for HF and H3PO4
4. Extreme wear and abrasion resistance., much better than stainless steel
5. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

Description of high purity   Si3N4 Silicon Nitride Ceramic
Silicon nitride ceramic offers exceptional thermal shock, extreme thermal stress resistance, excellent wear resistance, great chemical resistance, and easier machinable features. It’s always made use of producing refractory ceramic parts, anti-corrosion ceramic parts, ceramic seal parts, ceramic cutter/blade for machining.
Our company supplies a great of silicon nitride ceramic components, including Si3N4 ceramic tube, Si3N4 ceramic plate, Si3N4 ceramic rod, and various complicated silicon carbide ceramic structural parts.
