[0027] figure 2 It is a schematic flowchart of the steps of the manufacturing method of the nano-powder according to the first embodiment of the present invention. Please refer to figure 2 , the nano powder manufacturing method 200 generally includes steps S201-S209. First, as shown in step S201, a mixture is provided, and the mixture at least includes a first material and a second material. In this embodiment, the first material may be zinc oxide, and the second material may be indium oxide, aluminum oxide or magnesium oxide.

[0028] Nanopowders such as zinc oxide, indium oxide, aluminum oxide, and magnesium oxide are directly available in the market. However, if the size of the powder used is not nano-scale, preliminary mechanical grinding can also be carried out first. In particular, in step S201, the addition amounts of the first material and the second material may be determined according to a specific chemical composition. In the step of simply mixing solid powde...

[0046] FIG. 6 is a schematic flowchart of the steps of the method for manufacturing nanopowder according to the third embodiment of the present invention. The manufacturing method of nanopowder as shown in Figure 6 comprises steps S401~S409, relevant content is as follows figure 2 The fabrication method of the shown nanopowders is similar and will not be repeated here.

[0047] It should be noted that in step 401, a mixture is provided, and the mixture includes a first material, a second material and a third material. In this embodiment, the first material is zinc oxide, the second material is indium oxide, and the third material is gallium oxide. In this embodiment, the molar ratio of zinc oxide, indium oxide and gallium oxide is 2:1:1. After continuing to go through steps S402-S409, nanometer powder of indium gallium zinc oxide (IGZO) can be obtained.

[0048] In more detail, the general process is as follows: first mix powder materials such as zinc oxide (ZnO), indium o...

Abstract

The invention provides a method for manufacturing nano powder, which comprises: firstly, providing a mixture which at least comprises a first material and a second material; secondly, sintering the mixture to obtain a single-phase alloy body; thirdly, pre-crushing the single-phase alloy body to obtain powder to be ground; and finally, adding a chemical dispersant into the powder to be ground to obtain the nano powder.

Description

【Technical field】 [0001] The present invention relates to a method for manufacturing nano powder, and in particular to a method for preparing nano powder with any chemical composition. 【Background technique】 [0002] Large-area panels are the development trend of the display industry today, but large-area panels require a larger coating and lithography process platform, and it is relatively more difficult to maintain the yield rate. In order to overcome the above-mentioned difficulties, some researchers have proposed a jet printing technology, that is, after the conductive paste is spray-printed at a proper position, the printed pattern is properly processed to form a conductive film. [0003] Jet printing technology can be used to make channel layers or transparent pixel electrodes of thin film transistors in flat panel displays. In particular, jet printing technology can omit the yellow light lithography process, can cooperate with computer aided drawing design (Computer ...
