| 摘 要： | Aluminum borate whisker/aluminum phosphates composites were prepared with normal pressure sintering, It was found that the aluminum borate whisker was effective to suppress the crystallization of aluminum phosphates in the aluminum borate whisker/aluminum phosphates composites and contributed to the improvement of the mechanical properties. After sintered at 1050℃ for 1 h, the flexural strength of the composites with 30 vol% aluminum borate whisker addition reached 215.3 MPa. The dielectric constant and loss tangent of the composites were 4.23 and 0.0024 at 10 GHz.

| Abstract: | Aluminum borate whisker/aluminum phosphates composites were prepared with normal pressure sintering. It was found that the
aluminum borate whisker was effective to suppress the crystallization of aluminum phosphates in the aluminum borate whisker/aluminum
phosphates composites and contributed to the improvement of the mechanical properties. After sintered at 1050°C for 1 h, the
flexural strength of the composites with 30 vol% aluminum borate whisker addition reached 215.3 MPa. The dielectric constant
and loss tangent of the composites were 4.23 and 0.0024 at 10 GHz. |
