Reaction Sintering Reaction sintered silicon carbide, also known as self-bonding silicon carbide, refers to the process of reacting porous billets with gas phase or liquid phase to improve billet quality, reduce pores, and sinter the finished product with a certain strength and dimensional accuracy. The α-SiC powder and graphite are mixed in a certain proportion and heated to about 1650°C to form a billet. At the same time, it penetrates or penetrates into the billet through gas-phase Si, reacts with graphite to form β-SiC, and combines with the existing α-SiC particles. When Si is completely infiltrated, a reaction sintered body with complete density and no dimensional shrinkage can be obtained. Compared with other sintering processes, the dimensional change of reactive sintering during densification is small, and products with precise dimensions can be produced, but the presence of a large amount of SiC in the sintered body makes the high temperature performance of reactive sintered

Semiconductor Annealing The semiconductor chip needs to be annealed after ion implantation. Because when impurity ions are implanted into the semiconductor, the high-energy incident ions will collide with the atoms on the semiconductor lattice, causing some lattice atoms to be displaced, resulting in a large number of vacancies, which will make the arrangement of atoms in the implanted area disorder or become It is an amorphous region, so after ion implantation, the semiconductor must be annealed at a certain temperature to restore the crystal structure and eliminate defects. At the same time, annealing also has the function of activating the donor and acceptor impurities, that is, some impurity atoms in the interstitial position are annealed to allow them to enter the replacement position. The annealing temperature is generally 200~800C, which is much lower than the temp erature of thermal diffusion doping. Learn more: Analysis Of Leakage Causes Of Aluminum Alloy Plate Heat Exchanger
