摘要：

The electrical and mechanical properties of hot-pressed versus sintered LiTi2(PO4)(3) were investigated. The hot-pressed LiTi2(PO4)(3) had a higher density and larger average grain size than the sintered material. As a result of these microstructural differences the hot-pressed material exhibited a higher total ionic conductivity and lower hardness. The electronic conductivity of both materials was the same and increased by a factor of about 10(7) when the hot-pressed and sintered materials were heated under a reducing atmosphere.
