Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted at high temperature in a resistance furnace. The raw materials used in the manufacture of green silicon carbide, such as black silicon carbide, are roughly the same, and industrial salt is added as a reactant and accelerator to react in a resistance furnace. In terms of it...

As one of the important parts of lithium ion batteries, the diaphragm can avoid the positive and negative electrode contact and promote the shuttle of lithium ions between the two electrodes. It does not participate in the electrochemical reaction, but determines the performance and safety of the battery. Inorganic ultrafine powder coating or composite modified polymer is one of the effective meth...

Silicon carbide whiskers are cubic whiskers and belong to the same crystal type as diamond. It is the whisker product with the highest hardness, the highest modulus, the highest tensile strength, and the highest heat-resistant temperature among the whiskers that have been synthesized. There are two forms of α type and β type, and the performance of β type is better than that of α type. Type β has ...

As a new material of the technological revolution, ceramic materials have attracted the attention of some developed countries as early as more than ten years ago. The fatal shortcomings of ceramic materials are its brittleness, low reliability and low repeatability. These shortcomings have seriously affected the application range of ceramic materials. Only by improving the fracture toughness of ce...

Manganese dioxide (chemical formula: MnO2) is a black or brown solid, the most stable oxide of manganese, and is often found in pyrolusite and manganese nodules. Pylusite is the main mineral containing manganese; manganese nodules (submarine rock solids) also contain manganese. Manganese dioxide is mainly used to make dry batteries, such as carbon-zinc batteries and alkaline batteries; it is also ...

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...
