High purity spherical β-Si3N4 particles were synthesized via an efficient carbothermal reduction–nitridation strategy by precise regulation. The results showed that nano-sized reactants with an appropriate ratio was significant for acquiring Si3N4 granules with pure β phase. c/a,b-axis length ratio...
