NSiC bricks have excellent thermal and chemical stability. We provide high quality NSiC Brick with wholesale & sales at factory price.
NSiC bricks are refractory bricks made of silicon carbide (SiC) through a nitriding process. Silicon carbide is a compound consisting mainly of silicon atoms and carbon atoms. NSiC silicon nitride bricks have excellent thermal and chemical stability and are widely used in furnaces, kilns and other equipment involving high temperatures, corrosive environments and thermal cycling.
Excellent high temperature resistance
NSiC refractory bricks can withstand extremely high temperatures. Normal temperature strength maintains the same strength and hardness at 1200-1400°C as at normal temperature.
Thermal shock resistance
NSiC refractory bricks have excellent resistance to thermal shock, and will not crack or fracture in environments with rapid temperature changes. This property is critical in applications involving thermal cycling, where the material is subjected to alternating high and low temperatures.
NSiC fire bricks are highly resistant to chemicals; they are resistant to acids, alkalis and many other chemicals, thus extending their service life in aggressive industrial processes.
NSiC bricks have good mechanical strength and can withstand mechanical stresses and loads. They have high flexural strength and maintain structural integrity even under heavy loads or vibrations.
Low thermal expansion
NSiC bricks have a low coefficient of thermal expansion, which means they expand and contract very little during temperature changes. This property reduces the risk of thermal stress and cracking, especially during sharp temperature changes.
Good thermal conductivity
The high thermal conductivity of NSiC refractory bricks helps to reduce thermal resistance and increase thermal efficiency, allowing for efficient heat transfer. This property facilitates uniform heat distribution or rapid heat extraction.
NSiC bricks have a degree of electrical conductivity that is advantageous in specific applications, such as heating elements or components that require electrical conductivity at high temperatures.
NSiC bricks have a dense microstructure due to their low porosity. This property enhances its resistance to chemical attack, thermal shock and erosion.
NSiC fire bricks are customizable and can be tailored to your needs, making it easy to produce bricks with high dimensional accuracy and compliance.
Furnaces and kilns
NSiC bricks are widely used in the construction of high-temperature furnaces and kilns. They can withstand extreme heat and thermal cycling, making them ideal for applications such as heat treatment furnaces, ceramic kilns and incinerators.
NSiC bricks are used in the production of aluminum and its alloys. They are used in the construction of crucibles, ladles and other equipment for melting, holding and casting molten aluminum. the chemical and thermal shock resistance of NSiC refractory bricks is an ideal material for the production in aluminum plants.
NSiC refractory bricks are widely used in the petrochemical industry because of their excellent resistance to corrosion and high temperatures. They can be used in processes such as crackers, reformers and reactors.
NSiC bricks are used in various applications in the steel industry. They can be used in the construction of ladles, intermediate ladles and other equipment used to process steel.
NSiC refractory bricks are used in the ceramic industry for kiln construction and kiln furniture. They can withstand the high temperatures required for ceramic firing and have excellent thermal stability and resistance to chemical attack.
NSiC bricks are used in the glass manufacturing process. They are used as refractory linings in glass furnaces and are resistant to high temperatures and the chemical attack of molten glass.
NSiC firebricks are used in a variety of chemical processing applications that require resistance to high temperatures, corrosive chemicals and thermal cycling. They are used in reactors, furnaces and vessels in chemical manufacturing processes.
