Nanomaterials exhibit many exotic properties that traditional materials do not have. The first thing we need to know is that the nanometer (mainly refers to less than 100nm) of the composition of nanomaterials has four major effects: 1. Small size effect The boundary conditions of the crystal periodicity are destroyed; the atomic density near the surface layer of the amorphous nanoparticle decreas...

Transmission Electron Microscope (TEM) Transmission electron microscopy uses an electron beam that penetrates a sample to image, which requires the sample being observed to be "transparent" to the incident electron beam. Transmission electron microscopy is widely used in materials science and biology. Since electrons are easily scattered or absorbed by objects, the penetration is low, and the dens...

This is a method of synthesizing boron nitride by reacting borax and ammonium chloride as the main raw materials in an ammonia atmosphere. The two raw materials should be dehydrated and recrystallized separately before participating in the reaction. Borax is best dehydrated in a vacuum at 200~400°C. The recrystallization of ammonium chloride is to dissolve it into a saturated solution, filter to r...

The synthesis of boron nitride by nitridation with boron anhydride (B4O3) is one of the important methods for industrial production of boron nitride. Due to the low melting point of boron anhydride (glass state is 294°C, crystalline state is 450-600°C), it becomes a high-viscosity melt at the nitriding temperature, which hinders the flow of ammonia and makes the reaction slow and extremely incompl...
