| Abstract: | Ultrafine SiC platelets as an ideal toughening material, has substituted SiC fiber which is dear and hardly prepared, because of its high strength, high modulus of elasticity and thermal conductivity. The methods of preparation for SiC platelets are chemical process and mechanical process. The preparation of SiC platelets by means of mechanical grinding was discussed. The work principle on manufacturing process and its advangtages and disadvangtages were elaborated. Compared with different methods, it was found that the technics adopting jet mill and classifier was effective and the most effectual to prepare ultrafine SiC platelets at present. |
