The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.

Silicon Carbide (SiC) has emerged as a key material in the field of semiconductor technology, offering exceptional properties that make it highly desirable for various electronic and optoelectronic applications. The production of high-quality SiC single crystals is crucial for advancing the capabilities of devices such as power electronics, LEDs, and high-frequency devices. In this article, we delve into the significance of porous graphite in the Physical Vapor Transport (PVT) method for 4H-SiC single crystal growth.

Ion implantation is a method of semiconductor doping and one of the main processes in semiconductor manufacturing.

Silicon nitride (Si3N4) is a key material in the development of advanced high-temperature structural ceramics.

Wafer cleaning refers to the process of removing particulate contaminants, organic contaminants, metal contaminants, and natural oxide layers from the wafer surface using physical or chemical methods before semiconductor processes such as oxidation, photolithography, epitaxy, diffusion, and wire evaporation. In the semiconductor manufacturing, the yield rate of semiconductor devices largely depends on the cleanliness of the semiconductor wafer surface. Therefore, to achieve the cleanliness required for semiconductor manufacturing, the rigorous wafer cleaning processes are essential.

With the development of semiconductor and optical technologies, glass wafers as the new type of glass product, are gradually becoming a complement to silicon wafers, showing great potential in the field of high technology. What are the glass wafers? Glass wafers are the high-performing circular thin slices, commonly made of quartz glass, alkali-free glass, or glass-silicon composites. With excellent physical and chemical properties, they play an irreplaceable roles in cutting-edge manufacturing fields, such as semiconductor manufacturing, optics, MEMS, consumer electronics, biomedicine, and laboratory research.
