Product detail
Silicon nitride ceramic, represented by the chemical formula Si3N4, is a vital material in the field of structural ceramics due to its exceptional overall performance. It exhibits impressive properties including high flexural strength, fracture toughness, wear resistance, and thermal shock resistance, positioning it as one of the top-performing materials among fine ceramics. Silicon nitride ceramic showcases remarkable temperature resistance, as its mechanical strength can be maintained even at temperatures as high as 1200 ℃. Moreover, it resists infiltration and corrosion from various molten metals and alloys, such as aluminum, lead, tin, silver, brass, nickel, and more.
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.
After sintering, silicon nitride ceramic exhibits exceptional hardness, necessitating machining with diamond tools.
