Patent ID: 8828281

Claim:
Process for obtaining ceramic composites consisting of the following steps: a. starting from a β-eucryptite phase solid solution of an LAS component in accordance with the composition Li x Al y Si z O w , where x varies between 0.8 and 1.2, y varies between 0.8 and 1.2, z varies between 0.8 and 2, and w varies between 4 and 6, b. mixing the β-eucryptite phase solid solution of the LAS component obtained in a) with SiC in an attrition mill operating at over 100 rpm, wherein SiC is in the form of nanoparticles with a mean particle size less than 100 nm, for obtaining a stable, homogeneous suspension with a content in β-eucryptite less than 75% by volume, c. drying of the resulting suspension, d. shaping of the material obtained in c), e. sintering of the material obtained in d).
