Abstract
A cellulose nanocrystal-modified ceramic blank and a preparation method thereof are disclosed. Cellulose nanocrystals are added into a ceramic blank in gelcasting. The cellulose nanocrystal-modified ceramic blank comprises, by weight, 0.1 to 10 parts of cellulose nanocrystals, 0.1 to 30 parts of organic gel and 70 to 99 parts of ceramic powder. The cellulose nanocrystal has length of 100 to 300 nm, a diameter of 10 to 20 nm, a slenderness ratio of 10 to 15 , and an elastic modulus of 100 to 150 GPa. The drying strength of the ceramic blank with the cellulose nanocrystals is obviously improved.
