Experimental studies and applications of vanadium oxides.The electrical and electrochemical properties of V-5 and V-7 vanadium oxides were investigated. The effects of pressure, temperature and moisture on the bulk resistivity of the oxides in powder, sintered, and crystalline form were determined, and the static and dynamic volt-ampere characteristics were obtained. Sintered samples tested showed better electrical stability than the compressed powder samples. Two types of commercially available vanadium pentoxide were heat-treated to obtain various crystalline oxide forms which were mounted on alumina substrates and terminated by thick-film conductors for making electrical connections. Indications are that these materials could have applications as sensors, critical-temperature resistors, high-speed switches, and temperature-compensation elements in hybrid microelectronic circuits.
