Australian scientists have developed a new type of metal glass electrode that can be used in electron microscopy and other instruments

according to a recent report by the American physicist organization in the latest issue of the journal Physical Review express, they have developed a new type of metal compound with properties similar to glass, and used it to replace plastic and combine with carbon nanotubes to make a new field emission electrode. The field emission electrode can produce stable electron beams and is expected to be used in the fields of consumer electronics and electron microscopy

in the past, scientists mainly made field emission electrodes by embedding carbon nanotubes and other nano materials into plastics. Although these field emission electrodes have a wide variety and are easy to manufacture, and have great application potential, they also have many defects. For example, the conductivity of plastic is too weak. One is pressure; The thermal stability of plastics is so low that they cannot resist the large amount of heat generated by long-term operation

now, the scientific research team of Monash University in Australia and the scientists of the process science and Engineering Research Institute under the Commonwealth Scientific and industrial research organization in Australia have jointly developed a new material with great application potential and easy to manufacture - amorphous metallic glass (ABM), and used it to replace plastic to manufacture field emission electrodes. When these amorphous block metallic glass alloys cool, they will form amorphous materials, making their every move more like glass

this amorphous block metallic glass alloy is made of magnesium, copper and rare earth element gadolinium, which has many unique characteristics of plastics; It can be manufactured in large quantities and can be used as an effective substrate for carbon nanotubes. In addition to its excellent electrical conductivity, this metallic glass also has very stable thermal properties, which means that it can maintain its shape and durability even under high temperatures. Scientists say that the above advantages and its excellent electric LCD large screen full picture display of experimental data, consequences and curve sub emission properties make this amorphous block metallic glass one of the best materials for manufacturing electronic emission equipment

although some scientists have developed other composite materials composed of large metallic glass and carbon nanotubes, this is a "one turn" that is a transformation: from traditional low value-added products to high-performance, high value-added product systems, which are first used to manufacture functional equipment such as field emission electrodes. The scientists said that this technology can be operated according to the document instructions and is used to manufacture electron microscopes, microwave and X-ray generation equipment and modern display equipment
