US Patent for Silicon carbide whisker reinforced alumina …
Alumina chromia solid solution gives greater Young''s modulus than pure alumina does, thus, stronger matrix phase is expected in this newly invented composite. In addition, the ionic diffusivity of the alumina chromia solid solution is greater than pure alumina and the sintering temperature may be substantially reduced for saving energy.
