Performance of silicon carbide (SiC) whisker:
1. SiC whiskers is the important new high-tech materials, is the strengthening and toughening agent for metal matrix, ceramic
matrixand polymer-based composites and other advanced materials, has been widely usedin ceramic knives, space shuttle,
automotive parts, chemicals, machinery andenergy production.
2. SiC whiskers is mainly used in ceramic cutting tools and wearresistant high temperature toughened coatings.
3. In cutting tools, stone saws, textile cutter, blasting nozzle,high temperature extrusion die, seal rings, armor, etc. have great market
demand.
Description for silicon carbide whisker:
1. Physical characteristics: the cubic crystal,and part of a single diamond crystal.
2. Chemical properties: abrasion, high temperatures, especially heat-shock resistance, corrosion resistance,radiation.
3. Purpose applications: high-grade ceramicbearings, molds, jet nozzle high pressure, high temperature coatings.
About silicon carbide whiskers dispersed:
Silicon carbide whisker is gray-green powder fromvisual, only uniformly distributed in the matrix material and then could playthe best reinforcement toughening effect. Therefore, must be focus on doingwhiskers dispersed. The steps of dispersing as following:
1. selected dispersion medium. Water, ethanol,isopropanol ,etc.
2. selected dispersant.
3. adjust the PH value of the dispersion medium.Generally can be adjusted to 8.
4. stir evenly
