a)According to Reaction(1);b)according to Reaction(2).

The grain size was measured from the SEM images.Each reported value was averaged from~400 grains.The modulus and Vickers hardness of the as-sintered ceramics were determined by a mechanical resonance frequencies machine(GrindoSonic,Model MK7,Sweden)and a Vickers Hardness Tester(Durascan50,Struers,Austria),respectively.For the hardness test,hardness values were compared under different loads(0.2,1 and 5 kg)at the same holding time of 15 s.The fracture toughness of HEB was calculated by direct crack measurements according to Anstis equation[43],based on the crack generated by the indents with a load of 5 kg.A typical indentation image for the crack measurement was shown in Fig.S1.
