Mascera är en professionell leverantör för tekniska keramiska delar, vi tillhandahåller specialtillverkning för aluminiumoxidkeramik, zirkoniumoxidkeramik, bornitridkeramik, kiselnitridkeramik, kiselkarbidkeramik, aluminiumnitridkeramik och bearbetbar glaskeramik.

Kiselnitridkeramik, kemisk formel Si3N4, är ett viktigt strukturellt keramiskt material med bra omfattande prestanda. Egenskaperna för böjhållfasthet, brottseghet, slitstyrka, termisk chockbeständighet rankas högt bland all fin keramik. Kiselnitridkeramik har extremt hög temperaturbeständighet, den mekaniska styrkan kan bibehållas till en hög temperatur på 1200 ℃. Mascera kunde bearbeta kiselnitridkeramik till en mycket slät yta och med hög storleksnoggrannhet enligt kundernas design.

Product detail


Silicon nitride ceramic, chemical formula Si3N4, is an important structural ceramic material with good comprehensive performance. The properties of flexural strength, fracture toughness, wear resistance, thermal shock resistance are ranking high among all fine ceramics. Silicon nitride ceramic has extremely high temperature resistance, the mechanical strength can be maintained to a high temperature of 1200 ℃. Silicon nitride ceramic will not be infiltrated or corroded by many molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc. 


Benefiting from the excellent comprehensive performance, silicon nitride ceramic can be used in many severe mechanical, thermal, chemical, wear applications, it will greatly improve the reliability, performance and working life of workpieces, reducing the frequency and cost for replacement.


Silicon nitride ceramic has very high hardness after sintering and must be machined by diamond tools. Mascera could machine silicon nitride ceramics to a very smooth surface and in high size accuracy according to customers' designs. We could support for both prototyping and bulk order, our aim is to be your best partner for technical ceramic parts.
