Article Preview

A new method for producing silicon carbide platelets with low cost and high yield was introduced. The silicon carbide platelets were synthesized by double-heating technique with carbon black and SiO2 powder as raw materials without using any catalysts. The starting mixtures were heated at a temperature in the range of 1800-2000°C for the duration of about 2-4h to produce substantially completely unagglomerated silicon carbide platelets with the thickness of 5-15μm and the average diameter of 50-150μm. Compared to the conventional heating, double-heating technique has different heating mechanism and has advantages of less investment for equipment, easy to manufacture and convenient to operate. Furthermore, it is very suitable for realizing the scaled production because of the lower synthesizing temperature, shorter reaction time and greater output.
