Silicon Nitride Powder Si3N4 Introduction
Silicon nitride
This is an organic substance. The chemical formula for it is Si3N4. The relative molecular masses are 140.28. It can be gray or off-white.
Silicon Nitride Si3N4 Pulp Powder – Physical and Chemical Properties
Si3N4 has high temperature insoluble properties. It is highly resistant to high-temperature creep. Hexagonal system. The crystals of the Hexahedral system are hexagonal. Si3N4 is dense by reaction sintering. Si3N4 is about 1.8 to 2.7 g/cm3. Si3N4 is density by hot-pressing. It is 3.12-3.22g/cm3. Mohs hardness (99.5), Vickers hardness (2200) and microhardness (32220MPa) are all 99.5. It is known as the 1900 melting point (under pressure). The melting point is 1900 under pressure. It has a specific heat capability of 0.71J/g*K. The heat of formation for a given material is 751.57kJ/mol. The thermal conductivity of the material is 2-155 W/(m*K). The linear expansion coefficient is 2.8~3.2×10-6/(20~1000).
It is insoluble in water. Insoluble in water. Temperature at which oxygenation starts in the air is 1300-1400 At 20°C, the specific volume resistance of air is 1.4×105*m and at 500 it’s 4×108*m. The elastic modulus measures 2842046060MPa. It has a compressive force of 490MPa when it is react sintering. Calcium diazide is formed when it reacts to dicalcium diazide at 1285. At 600, it is reduced to a transition metal and released nitrogen oxides. The bending strength is 147MPa. This can be achieved by reacting silica halide and ammonia with silicon powder. This material has a resistance of between 1015-1016O.cm. You can use it as a high-temperature ceramic material.
Other than hydrofluoric acid or hot phosphoric acids, silicon nitride doesn’t react with any other inorganic substances and is highly resistant to corrosion.
Silicon Nitride Si3N4 Pulverization
High thermal stability and oxidation resistance are some of the benefits that silicon nitride ceramic materials offer. The covalent compound silicon nitride has high bond strengths and can form oxide films in the air. It also exhibits good chemical stability. It is resistant to oxidation below 1200. To protect it, a protective layer can be created at 1200-1600. While silicon nitride does not become infiltrated, corroded, or infiltrated with aluminum, lead or zinc, silver or brass, as well as many other molten alloys and metals, it can still be corroded or affected by nickel-chromium alloy, magnesium, and other liquids.
Ceramic materials made of silicon nitride can be used for their applications high-temperature engineering components , The metallurgical Industry: Advanced Refractory , Corrosive-resistant components Sealing parts in the chemical, machining, and cutting industries.
Silicon nitride is able to form strong bonds with silicon carbide (alumina), thorium oxide, and boron nitride so it can be used in different combinations.
Additionally, silicon nitride may be used in solar cells . Once the silicon-nitride nitride is coated using the PECVD technique, it can be used for antireflection to reduce reflections of incident light. However, during the deposition of a silica nitride movie, the hydrogen atom from the reaction product enters silicon nitride wafer and the silicon silicon nitride nitride photovoltaic device, where it plays a function as passivation defect. There is no set ratio for silicon nitride to silica nitrogen atoms. It fluctuates depending on different technological conditions. Different atomic proportions are associated with different properties.
You can use it in Gas turbines and aircraft engines at ultra high temperatures, as well as electric furnaces , etc.
