zeta potential measurement for silicon carbide in india

Measuring Silicon Carbide Particle Size

Silicon carbide (SiC) has a range of physical properties that makes it a versatile and useful material. It is one of the hardest materials known, second only to diamond, has a relatively low density (approximately the same as aluminum), good wear and corrosion resistance and low thermal expansion and high thermal conductivity leading to excellent thermal shock resistance.

Effect of pH on the dispersability of silicon carbide

01/04/1999· The zeta potential measured for three SiC powders presented in Fig. 9 shows almost similar behaviour with negative zeta potential values over a substantial pH range demonstrating the acidic character of SiC. All the three powders show a maximum in the zeta potential values at PH=10 indiing that the slip is well dispersed at this pH.
