Silicon Carbide Nozzle Data Sheet

Silicon Carbide Nozzle Description

Silicon Carbide (SiC) primarily exists in two crystal structures: the cubic β-SiC and the hexagonal α-SiC. Compared to other ceramics such as alumina (Al2O3) and boron carbide (B4C), SiC exhibits superior mechanical properties, better oxidation resistance, higher wear resistance, and a lower friction coefficient. Silicon Carbide Nozzle is made from high-purity reaction-bonded silicon carbide (RBSiC) or sintered silicon carbide (SSiC), featuring high-temperature resistance (1600-1800℃), wear resistance (Mohs 9.5), and corrosion resistance. It is widely applied in steel casting, chemical jetting, and PV cleaning applications. NexusX can supply high-precision silicon carbide nozzles with customized solutions for diverse industry and research applications.
