The reason why tungsten needles can be used in microscopes is that they have some special properties and characteristics that make them suitable for various applications in microscopes. Here are some reasons:
High melting point: Tungsten material has an extremely high melting point, about 3410 degrees Celsius. This allows this mental needle to withstand high-temperature environments in the applications of microscopy, such as electron microscopy, where they are used to generate beams of high-energy electrons. Its high melting point ensures that the needle can work stably for a long time without melting or losing its shape.
High hardness and wear resistance: Tungsten is a very hard material with excellent wear resistance. In the applications of microscopy, they are often required to contact and manipulate sample surfaces, and their high hardness and wear resistance allow them to withstand these stresses and maintain a long service life. In addition, its hardness can also provide high-resolution imaging and detection capabilities.
Sharpness and Small Size: W needles can be fabricated into very sharp and small shapes, enabling them to achieve extremely high spatial resolution in microscopy applications. This allows them to be used for atomic-scale imaging, surface topography measurements, and sample manipulation, as in atomic force microscopy and phonon scanning tunneling microscopy.
Excellent conductivity: Tungsten is an excellent conductive material with low resistivity and high conductivity. This enables them to provide stable electron flow and electrical signal transmission in electron microscopy and electrochemical applications.
Given that, tungsten needles are an ideal material for various microscopy applications. They can withstand high temperature, high stress environments, provide high-resolution imaging and detection capabilities, and have long life and stability, thus providing reliable tools and support for research and analysis of microscopy.
