High-quality UTe$$_2$$ single crystals were grown using a molten salt flux method with the highest reported superconducting (SC) transition temperature. The crystals had a small residual electronic contribution in specific heat and a large residual resistivity ratio. The SC phase diagram of UTe$$_2$$ was studied, revealing contrasting field-angular dependence of low and high-field SC phases. An intermediate SC state was also found. The high-field SC phase appeared consistently at about 15 T, while crystal quality increased the upper critical field of the low-field superconducting phase. The MSF method facilitated the observation of quantum oscillations and progress in Fermi surface research for this spin-triplet superconductor.
