1.Characteristics of alumina tube
Resistance to High Temperatures
Because of their exceptional thermal stability, alumina tubes can withstand temperatures up to 1500°C. This makes them perfect for use in high-temperature applications including furnaces, kilns, and thermal processing systems.
Superior Mechanical Strength
Alumina tubes possess remarkable mechanical properties, such as high strength and hardness. Their hardness ensures resistance to wear and abrasion, making them suited for use with abrasive materials. Alumina tubes also have remarkable fracture toughness, which enables them to withstand thermal shocks and mechanical impacts without breaking.
Chemical Stability
Alumina tubes exhibit outstanding chemical stability, which means that they have great resistance to corrosion caused by a wide variety of acids, alkalis, and solvents. Due to this characteristic, they are appropriate for application in laboratory settings, chemical processing, electroplating, and other environments requiring corrosion resistance.
Electrical Insulation
Alumina tubes are extensively used in electrical insulating applications and electronic devices due to their superior electrical insulation. They are perfect for high-voltage applications and as electrical feedthroughs in vacuum systems because they continually provide insulation and protection against electric currents.
Customized Design
Alumina tubes can be tailored to varying sizes, shapes, and part configuration to fulfill specific application needs. Whether round, square, rectangular, or specialized designs, UNIPRETEC can customize the ceramic tubes to fit unique engineering designs and installation needs.
2.Characteristics of Zirconia Tube
Low Thermal Conductivity
Zirconia tubes function as excellent thermal insulators and thermal barriers in some applications due to their low thermal conductivity.
Chemical Inertness
Zirconia tubes are extremely resistant to chemical corrosion, making them ideal for applications that need exposure to harsh chemicals or corrosive substances.
Abrasion Resistance
Zirconia tubes have great resistance to abrasion, making them advantageous in situations where components are subjected to high levels of abrasive forces.
Dimensional Stability
Zirconia tubes are a dependable option for applications needing precise tolerances since they remain their size and shape even under the most challenging conditions.
3.Characteristics of Silicon Nitride Tube
Silicon nitride ceramics are covalent compounds composed of silicon and nitrogen atoms. The silicon nitride tubes have the following characteristics:
Superior Thermal Shock Resistance
Silicon nitride tubes exhibit exceptional thermal shock resistance and thermal stability. This indicates that they are resistant to fracturing or cracking in the face of sudden temperature changes. Because of this characteristic, they can be used in high-temperature environments like industrial furnaces, aerospace components, and automotive engines.
High Strength and Durability
Silicon nitride tubes have notable mechanical properties, such as outstanding toughness and strength, resistance to fracture and deformation when subjected to heavy loads, and so forth. Even under challenging and stringent operating conditions, they can guarantee dependable performance.
Wear Resistance
Silicon nitride tubes have excellent wear resistance, allowing them to endure abrasive contact and sliding forces while reducing the need for frequent replacements. This improves operational efficiency and prolongs service life.
Corrosion Resistance
Silicon nitride tubes are chemically inert, which ensures their longevity in applications involving chemicals or corrosive substances.
Dimension and Shape
Ceramic tubes can be made in a variety of shapes, such as round, square, and rectangular, etc. The dimensions can be precisely modified to match the application's unique requirements.
Surface Finish
Depending on the use, the surface of a ceramic tube can be finished from rough to polished, to ensure optimal performance and operation.
Tolerance and Accuracy
High precision and tight tolerances are both achievable in the production of ceramic tubes.
Factors Influencing the Price
Production Method
Methods such as extrusion, isostatic pressing, and slip casting have different cost implications. Extrusion might be less expensive for standard shapes, while isostatic pressing is used for high-precision components, increasing the price.
