Density, surface tension, and viscosity of liquid Si–Cr alloys and influence on temperature and fluid flow during solution growth of SiC

Solution growth using a Si–Cr-based solvent is promising process to produce high quality 4H–SiC single crystal. Computational fluid dynamics simulation an effective method estimate and control the temperature flow in process, although simulations are presently performed physical properties of liquid silicon due lack data for alloy solvent. In present work, density, surface tension, viscosity Si–18, 40, 50 mol% Cr alloys were measured by electrostatic levitation. was carried out melt compared with those silicon. Simulation Si–40 mol%Cr predicted larger velocity smaller distribution solution than pure
