Abstract
A nm-class multi-element voltage-sensitive material in the form of powder for manufacturing miniature voltage-senstive resistors in different voltage ranges is prepared from chemical-purity zinc acetate as main raw material, triethanolamine as solvent, citric acid as complex, organic salt, inorganic salt and rare-earth salt by sol-gel method. Its average granularity is in the range between more than 10 and tens nm.
Description
The present invention relates to a kind of multielement nanometre voltage sensitive powder material and manufacture method thereof
Zinc oxide varistor is the very promising semiconductor sensor spare that the seventies grows up, and in the field of all electricity consumptions such as industrial electrical equipment, power equipment, traffic communication, instrument, aerospace, unicircuit, computer, household electrical appliance its purposes is widely arranged all.The at present domestic material that is used to make piezoresistor is that the mechanical ball milling method prepares micron-sized powder with traditional method usually, begin abroad to have reported with the synthetic ultramicrofine pressure-sensitive powder of chemical process from the nineties, though each breadboard flouring technology difference can reduce two class ie in solution coprecipitation method and sol-gel processings.The present invention prepares on the basis of ultra tiny pressure-sensitive powder body material absorbing and improve external chemical process, adopt the colloidal sol-polynary pressure-sensitive powder of gel method composite powder footpath about 20nm, and on this basis, by a large amount of tests, synthesized the pressure-sensitive powder body material of nano level of the miniature piezoresistor that is used for the manufacturing property excellence.
The object of the invention is, having developed a kind of multielement nanometre voltage sensitive powder material and manufacture method thereof, is based on the chemical pure zinc acetate, is solvent with the trolamine, with the citric acid is complex compound, add organic salt again, inorganic salt, rare-earth salts, synthetic with sol-gel processing, can make polynary pressure-sensitive powder body material, its median size does not wait to tens nanometers from tens nanometers, and satisfies the pressure-sensitive powder body material of the miniature piezoresistor of making different voltage ranges.
