Nanooxide-doped green solder glass and preparation method thereof

Abstract

The invention discloses nanooxide-doped green solder glass and a preparation method thereof. The nanooxide-doped green solder glass is characterized by comprising the following raw material components by molar percent: 35%-50% of P2O5, 20%-45% of ZnO, 0.1%-20% of B2O3, 1%-10% of Al2O3, 0.1%-10% of SiO2, 0.1%-10% of Na2O, 0.1%-10% of MgO, 0.1 %-5% of Li2O, 0.1%-4% of Fe2O3, 0.1%-4% of MnO2 and 0.1%-1% of colorant chromium oxide. The preparation method comprises the following steps: mixing raw materials, and adding nanoalumina finally and mixing to prepare a mixture; putting a crucible into an electric furnace with the temperature of 1200-1400 DEG C, and preheating for 15 minutes; adding the mixture into the quartz crucible, melting at the melting temperature of 1200-1400 DEG C, and holding for 80 to 120 minutes; pouring the melted glass liquid into water or being ground into powder by a ball mill after tablet forming. The invention has the advantages of simple preparation, convenient operation, high performance cost ratio and broad market development prospects.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic glass, in particular to a green solder glass doped with nano-oxide and a preparation method thereof. 【Background technique】 [0002] Nano is a scale concept, which is one-billionth of a meter, and has no physical connotation. When the material reaches the nanometer scale, the properties of the material will change suddenly, and special properties will appear. Since the 1990s, nanotechnology has shown bright application prospects due to its novelty and uniqueness, and has achieved a series of key breakthroughs. Due to factors such as this field has a huge imagination space, development prospects, and potential scope for huge changes. , its research and application has been widely and highly concerned by countries all over the world. [0003] Before elaborating on adding nanomaterials to change the sealing performance of glass, it is necessary to introduce the characteristic structure of nano...

Problems solved by technology

The free volume defect is a kind of shallow trapping potential, but it can account for more than 90%. As the grains coarsen, the size and concentration of nano voids will change significantly. This type of defect will affect the interface of nanocrystalline materials. Great influence on structure and performance

The STM scanning current makes the superclusters in the nanocrystal tend to be arranged and the structure is ordered, but there is no structural rearrangement in the atomic force microscopy study
