What is Silicon nitrides?Silicon nitrides (Si3N4) feature an excellent combination of material properties. The microstructure consists of elongated crystals that interlock into micro-rods. One application where this combination of properties has prov...…
The PECVD process involves the deposition of silicon nitride on a semiconductor wafer. This coating acts as an etch stop and a stressor to improve mobility. The hydrogen content in the coating is a major factor in determining the final residual stres...…
LPCVD is a process in which thin films of semiconductor material are deposited on both sides of the wafer. The resultant layers have an excellent conformal coating, high breakdown voltage, and dielectric isolation. These films are used for many appli...…
The longer stacking sequence results in the α-phase having higher hardness than the β-phase. However, the α-phase is chemically unstable compared with the β-phase. When a liquid phase is present at high temperatures, the α-phase always transforms int...…
Silicon nitride. A cleaner alternative is spark plasma sintering, where heating is conducted rapidly (seconds) by passing pulses of electric current through the compacted powder. Dense silicon nitride compacts have been obtained by this technique at ...…
What is Silicon nitride?Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si3N4 is the most thermodynamically stable and commercially important of the silicon nitrides, and the term "silicon nitride" commonly refers to this...…
The ceramic material silicon nitride is an inorganic ceramic that doesn't shrink during the sintering process. Silicon nitride has a high strength, particularly hot-pressed silica nitride which is one the hardest materials. It possesses high strength...…
What is Silicon Nitride? Silicon nitride has an organic chemical formula of Si3N4. It is an important structural ceramic material, with high hardness and inherent lubricity. It also wears well. It is also resistant to heat and cold. It is resistan...…

Silicon nitride Ceramics and silicon nitride Ceramics Silicon nitride An inorganic substance with chemical formula Si3N4. It's an important structural ceramic material that has high hardness, intrinsic lubricity and wear resistance. It's an atomi...…
Silicon nitride You can obtain this chemical reaction at 1300-1400degC by directly chemically reacting elemental silicon with nitrogen. Here is the chemical formula 3Si(s) + 2N2(g) -Si3N4(s) This can be made with diimine. SiCl4(l) + 6NH3(g) -...…
Silicon nitride An inorganic substance of the chemical composition Si3N4. It's a structural ceramic material that is important for its high hardness, intrinsic lubricity and wear resistance. The atomic structure of silicon nitride has high resistanc...…
Susano Paper and Pulp, the Brazilia-based company that is the world's largest pulp producer, has warned that global pulp stocks have been falling sharply and are facing shortages that could lead to higher prices for necessities such as paper towels a…
Cement foaming agent is called foamed concrete foaming agent. It refers to an admixture that can reduce the surface tension of liquid and produce a large amount of uniform and stable foam. It is an admixture used to produce foamed concrete and can pr…
Many countries have begun to study digital currencies, which will have little impact on world boron carbide prices in 2021 The Bank of Japan plans to start empirical experiments on digital currencies in the spring of 2021. The idea is divided into 3…
