We demonstrate frequency conversion by four wave mixing at telecommunication wavelengths using an integrated platform in 3C SiC. The process was enhanced by high-Q and small modal volume ring resonators, allowing the use of mW-level CW powers to pump the nonlinear optical process. We retrieved the nonlinear refractive index $n_{ 2}=(5.31\pm 0.04)\times 10^{ -19} m^{ 2}/W$ of 3C SiC and observed a signal attributed to Raman gain in the structure.
