Dispersion and Additive amount of SiC Nanowires (for reference only)
Recommended dispersion media: deionized water, distilled water, anhydrous ethanol, ethylene glycol
Recommended dispersant:Polyethylene imine (PEI), nonionic polyacry lamide (PAM), sodium pyrophosphate (SPP), twain 80, silicon compound coupling agent, polyethylene glycol, sodium hexametaphosphate, sodium carboxymethyl cellulose (CMC), etc.
In ordinary ceramic matrix composites, silicon carbide nanowires less than 10wt% are generally added.In the process of specific optimization, it is recommended to start from 1wt% and gradually experiment and optimize. According to the experimental practice, the higher the adding amount is not necessarily the better, it is related to the raw material, material size, sintering temperature, reasonable adding amount can get the best toughening effect.
After mixing the dispersed SiC nanowire slurry and ceramic powder, continue to disperse for 1-12 hours. bead mill dispersion or mechanical stirring method is recommended. The ball milling method is easy to cause the nanowires to break.
