摘要： The invention relates to a method for obtaining ceramic compounds and to the resulting material, comprising the following steps: using as a starting compound an LAS component having composition LixAlySizOw, wherein 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; mixing the LAS component with SiC nanoparticles, thereby obtaining a stable homogeneous suspension; drying the resulting suspension; shaping the material obtained; and, finally, sintering the material obtained in the previous step. The resulting material has a density greater than 98% of theoretical density and can be used in the aerospace industry, microelectronics and precision optics.
