COAL WATER SLURRY NOZZLE, C/SIC ceramic Nozzle
Description
C / SiC ceramic matrix composites have the characteristics of good toughness, high temperature resistance, long service life below 1650 degrees, limited service life from 1650 to 2200 degrees, low density, good burning resistance, small coefficient of thermal expansion, strong performance designability and good formability. They can be used as an alternative to cemented carbide or ceramic burners. The utility model overcomes the needs of the service temperature of the cemented carbide, the complex structural design and the problems of the water cooling system, and overcomes the problems of the ceramic burner, such as poor toughness, poor heat shock resistance, poor machining performance and so on. The use of carbon silicon carbide ceramic matrix composites can simplify the structural form of the burner, with a service life of more than 90 days, and can save coal by 3% - 5%. Oxygen is saved by about 5%, and the carbon conversion rate is increased by 2% - 3%.

Work Application
C/SIC Ceramic MF is particularly suitable for applications requiring high wear resistance, high mechanical strength and low weight. In addition to its high thermal conductivity, this material exhibits the typical brittle fracture behavior of a ceramic. For this purpose, C/SIC Ceramic was used as material for the instrument panels of the satellite.
Ductile materials are obtained by incorporating short carbon fibers into a ceramic matrix. This material is characterized by a pseudo-plastic behavior under mechanical stress. The amount of carbon fibers in the ceramic matrix allows tailoring a wide range of mechanical and physical properties to your requirements. C/SIC Ceramic SF is established in the automotive industry for serial-produced C/SiC brake disks.
C/SIC Ceramic LF is especially suitable for applications under the highest mechanical stress. By incorporating long or continuous carbon fibers into a ceramic matrix, materials which are more dominated by the fiber properties than by the properties of the ceramic matrix are obtained. This material is characterized by a low density with high elongation at break and high strength. Today, /SIC Ceramic LF is mainly used in the field of ceramic C/SiC clutch disks for high-performance vehicles.
Composite materials with ceramic matrix
Ceramic matrix composite materials are a solution to the limit that advanced ceramics present for structural applications. Carbon-ceramic brake discs are made of a ceramic matrix (usually silicon carbide), and of high-strength carbon or silicon carbide fibers.
