Abstract: |
Tape casting green sheet of boron carbide ceramic with adequate strength and flexibility was prepared by tape casting. The effects of the specific surface area, dispersant, binder, plasticizer and ball milling time on the viscosities of the slurries were discussed. An optimum ratio was acquired for tape casting of boron carbide powder, the results showed that the green tapes prepared with specific surface area of 3.82m2/g of boron carbide powder, 2.0wt.% of dispersant, 0.75~1 of the ratio of plasticizer and binder, 12~16h of ball milling time, could fabricated a better mechanical.
