摘要：
Compact samples are produced from antimony-doped tin dioxide in a high-pressure cell at a hydrostatic pressure of 4 GPa and a temperature of 873 K. Pressure-temperature treatment has resulted in a material exhibiting high density and hardness. Its electrical and physical properties are studied. The temperature dependence of resistivity shows that the test material is a degenerate semiconductor with low (1.5 meV) activation energy.
