Effect of Si₃N₄ on Properties of Aluminum Borate Whisker/Aluminum Phosphates Ceramic

Abstract:

Aluminum Borate Whisker/Aluminum Phosphates composites (ABW/AP) added Si₃N₄ were prepared with pressure sintering technique. The influence of Si₃N₄ on the mechanical properties and dielectric properties were investigated. After sintered at 1050°C for 1h, the results showed that the flexural strength of the composites with 5wt% Si₃N₄ addition reach 167.29MPa,the dielectric constant (ε) and loss tangent (tanδ) of the composites are 2.99 and 0.0089 at 10GHz. The testing results was discussed.
