Problems solved by technology

[0004] The common method for preparing zinc oxide tetrapod whiskers is high-temperature oxidation, chemical reaction and gas protection, chemical reaction with carrier gas and raw materials and transport of reaction products, so that the products are deposited on the predetermined substrate under the action of the catalyst. But the yield is low, and the quality and purity of the product are not ideal enough

Embodiment 1

[0085] Preparation of zinc oxide hollow tetrapod whisker bundle:

[0086] Selected zinc oxide 0.5g, charcoal powder 1.5g, polyvinyl alcohol 0.7g, distilled water 0.3ml;

[0087] Put 0.5 grams of zinc oxide and 1.5 grams of carbon powder in an agate mortar, grind them into fine powder with a grinding rod, and then sieve them with a 300-mesh sieve, repeatedly grind and sieve, leave the fine powder, remove Coarse powder; dry the remaining fine powder in a drying oven at 60°C±3°C, mix the dried fine powder according to the combination ratio, and stir evenly with a magnetic stirrer, and then perform secondary grinding ;

[0088] Mix and stir 0.7 g of polyvinyl alcohol and 0.3 ml of distilled water under heating at 60°C±3°C to form a viscous solution, that is, polyvinyl alcohol solution, and then put the mixed and secondary ground zinc oxide and carbon powder into the In the polyvinyl alcohol solution, stir evenly to form a viscous material, then place the viscous material in seve...

Abstract

The invention discloses a preparation technique of zinc oxide hollow four-foot crystal whisker. The technique is adopted with zinc oxide, carbon powder as raw material, polyvinyl alcohol as adherent, pure water as dissolvent, passing through grinding, filtering, baking, blending, thick solution preparing, circular billet shaping, sintering, cooling, testing, analyzing, packing and finally storing, so to acquire zinc oxide crystal whisker of high purity. The technique is of simple operation, taking only a few device, low cost, high productivity and purity which reaches 99 percent. The raw material is of wide source widening the usage of zinc oxide to acoustic wave, light wave elements, photoelectricity sensor, plate displayer. The technique is an ideal production technique for the said crystal whisker.

Description

technical field [0001] The invention relates to a preparation method of a zinc oxide hollow tetrapod whisker bundle, belonging to the technical field of preparation and generation methods of nonferrous metal compounds. Background technique [0002] Zinc oxide is a multi-purpose non-ferrous metal semiconductor material. It is a wide-bandgap semiconductor material. It has hexagonal wurtzite and sphalerite crystal structures, and has high exciton binding energy. Its chemical and thermal chemistry Stable performance, zinc oxide film has good piezoelectric and photoelectric effects, can be used as surface acoustic wave, acousto-optic, and optical waveguide components, and low-resistance zinc oxide film can be used as window materials for solar cells, photoelectric sensors, and flat panel display devices. Its gas-sensitivity and pressure-sensitivity can be used to prepare gas-sensing sensors and pressure-sensing sensors. Since zinc oxide has various characteristics such as piezoel...
