ABSTRACT

Porous Si_100-xSn_x samples with x = 15, 30 and 40 at.% were produced from Si and Sn elemental powders by mechanical alloying followed by two different compaction and sintering processes: cold uniaxial pressure and subsequent sintering at 220°C, and hot pressing at 240°C. The results showed that it is possible to produce samples with a major porosity of close to 0.1 μm. The porosity of the Si₇₀Sn₃₀ sample that was mechanically alloyed for 12 h and synthesized by the former process is in the mesoporous region. The structure of all the final samples is composed of the Si, Sn and SnO phases.

通过机械合金化和随后通过烧结和热压固结生产的多孔 Si-Sn 合金

摘要

x = 15、30 和 40 at.% 的多孔 Si _100-x Sn _x样品是由 Si 和 Sn 元素粉末通过机械合金化然后两种不同的压实和烧结工艺生产的：冷单轴压力和随后在 220°C 下烧结，并在 240°C 下热压。结果表明，可以生产出主要孔隙率接近 0.1 μm 的样品。Si ₇₀ Sn ₃₀样品经机械合金化12 h后由前一种工艺合成，其孔隙率处于介孔区。所有最终样品的结构均由 Si、Sn 和 SnO 相组成。
