Application and Market Analysis of Silicon Nitride Ceramics
Silicon Nitride Powder Property
Silicon nitride (Si3N4) is a covalent bond compound made up of silicon and also nitrogen. It was found in 1857 and also was mass-produced as a ceramic material in 1955. Silicon nitride ceramics have lots of benefits that metal products as well as polymer materials do not have, such as high temperature resistance (bending toughness above 350MPa at 1200 ℃), acid and alkali rust resistance, self-lubrication and so forth. Silicon nitride ceramics are widely utilized in aerospace, national protection and also mechanical areas.
Prep Work Method of Silicon Nitride Ceramics
The prep work of silicon nitride ceramic material first needs to acquire silicon nitride powder, and afterwards via molding, sintering as well as various other processes, the needed silicon nitride ceramic is lastly obtained. the major preparation methods of the powder consist of silicon powder nitriding approach, liquid phase response method and self-propagating high temperature synthesis method.
The primary creating procedures of silicon nitride ceramics are completely dry pressing, cold isostatic pushing and also tape spreading, and the main sintering procedures are hot pushing sintering, air pressure sintering, hot isostatic pushing sintering, trigger plasma sintering and so on.
Silicon Nitride Ceramics Application in Mechanical Industry
Silicon nitride porcelains are primarily utilized as shutoffs, pipes, grading wheels and ceramic devices in the mechanical market, and one of the most extensively made use of is silicon nitride ceramic bearing balls.
The rate of silicon nitride bearing ball is as high as 600000 changes per minute in use, which is generally used in precision machine tool pin, mechanized spindle high-speed bearings, aerospace engines, automobile engine bearings as well as various other equipment bearings.
Compared to steel round, silicon nitride ceramic bearing sphere has impressive benefits: low thickness, heat resistance, self-lubrication and also rust resistance. As a high-speed revolving body, the ceramic round produces centrifugal anxiety, as well as the low density of silicon nitride lowers the centrifugal anxiety on the high-speed turning outer ring.
Thick Si3N4 ceramics additionally exhibit high fracture durability, high modulus as well as self-lubricity, which can resist a range of wear as well as stand up to harsh environments that might lead to cracks, deformation or collapse of other ceramic products, including severe temperature level, large temperature level distinction as well as ultra-high vacuum. Silicon nitride bearings are anticipated to be widely used in numerous markets.
Silicon Nitride Market Analysis
The production of premium silicon nitride ceramic items is still controlled by Japanese, European as well as American business. The international market share and the leading pressure of growth direction are still managed by well-known foreign ventures. Japanese Kyocera, Toshibx Seridan, CoorsTek as well as British Sailon are the most representative.
According to the worldwide marketing research company MARKETSANDMARKETS, the international market size of silicon nitride will certainly expand at a compound annual growth rate of 5.8% throughout the evaluation duration (2020-2027). From $1.4 million in 2020, it is expected to reach $149 million by 2027.
