An Overview of Industrial Ceramic Tube
The industrial ceramic tube is different from traditional porcelain ones, it can be concisely concluded as follows:
- Materials Science
The core materials for industrial ceramic tubes are refined high-purity non-metallic oxides, nitrides, and carbides, including aluminum oxide(Al2O3), zirconium oxide(ZrO2), aluminum nitride (AlN), silicon nitride (Si3N4) and silicon carbide (SiC), etc. They are suitable for use in extremely harsh working environments, such as ultra-high temperatures, high wear, high humidity, strong corrosion, and high current and voltage applications.
- Engineering Applications
Ceramic tubes play an important role in the precision industrial system behind the scenes, such as they are used as a wafer transmission tube resistant to plasma corrosion in semiconductor equipment, as a sterile and high-temperature laser scalpel tubing in the medical field, and as a liquid injection tube resistant to lithium battery erosion in new energy batteries.
- Industry value
When they are used as ceramic thermocouple protection tubes, they can reduce downtime and maintenance times by 50%. When they are used as electrical insulation tubes, the operating voltage can be up to 100 kV. When they are used with a ceramic body in an X-ray tube, the vacuum density can reach 10-11 Pa.m3/s. Industrial ceramic tubing is an innovative component with exceptional properties. They overcome the inherent defects of metal and plastic and reconstruct the equipment economic model with super-high temperature resistance, wear resistance, good insulation performance, corrosion resistance, and so on.
- Manufacturing process
Different from the traditional cutting process of metal tubing, industrial ceramic tubes are made by pressing or extruding powder through advanced molding equipment, like dry pressing, isostatic pressing, and extrusion machines, and are high-performance functional parts with millimeter size obtained by nano-level sintering shrinkage control.
- Market Positioning
Industrial ceramic tubes are the “entry threshold” for high-end manufacturing. For example, in the fields of aviation, aerospace, semiconductor equipment, high-temperature smelting, etc., it has changed from an “optional option” to a “must-have option”.
Unlike traditional tubes and pipes, customized formulas of ceramic materials are needed to achieve designated and distinguished properties. Sometimes, polishing and metalizing treatments are needed to extend their applications.
- Sustainability
You may not be aware of the merits of industrial ceramic tubes. Firstly, they are eco-friendly components; Secondly, the service life is 3~5 times longer than that of metal pipes. Thirdly, the energy consumption of the high-temperature sintering process is 60% lower than that of metal smelting, Fourthly, corrosion resistance avoids chemical contamination. The above are typical virtues of industrial ceramic tubing.
The types of ceramic tubes in the industries can be classified as multi-dimensional:
- Raw material
- Oxide ceramic, including alumina (Al2O3), zirconia (ZrO2), quartz (SiO2)
- Non-oxide ceramic, including aluminum nitride (AlN）， Silicon nitride (Si3N4), Silicon carbide (SiC), Boron nitride (BN)
- Shaping process
The regular shaping process for ceramic tubing covers dry pressing, hot pressing, extrusion, cold isostatic pressing (CIP), and ceramic molding injection.
- Sintering technology
Atmospheric pressure sintering is the most common sintering method; in order to improve the performance of the product, hot pressing sintering and microwave sintering are also used.
- Specific Uses
- Electrical & electronics: High-voltage ceramic insulator tube, fast-cooling aluminum nitride package tube
- High-temp industries: ceramic heater tube, thermocouple ceramic tube, molten metal delivery pipe
- Medical equipment: Ceramic co2 laser tube, zirconia surgical cannula, bioceramic implantation tube
- Chemical environmental protection: porous ceramic filter tube, acid-resistant zirconium composite tube
- New energy: fuel cell electrolyte tube, photovoltaic diffusion furnace tube
- By structural design
Ceramic tubes can be classified as single-layer, multi-layer, microporous tubes, and specially shaped tubes.
- By characteristics and properties
They can be classified as physical, mechanical, thermal, and electrical performance tubes.
- By industry standards
There are 4 typical industry standards, including
- General industrial grade: ASTM/ISO basic performance standards
- Food & medical grade: FDA/ISO 13485 biocompatibility requirements
- Semiconductor grade: SEMI standards (particle control < Class 10)
- Military-grade: MIL-STD extreme environment test
Ceramic tubes are a very hard industrial ceramic material, and professional tools and auxiliary facilities are required when cutting. The following is a list of items that need to be prepared before cutting:
※ Diamond saw blade or grinding wheel,
※ Cutting machine or angle grinding machine
※ Coolant (water or special coolant)
※ Protective equipment (goggles, masks)
※ Marking tools (marking pen)
※ Fixture & clamp
To ensure the quality of the cut ceramics, the cutting edge must be sharp as well as you must keep patient. You can conduct the processing step by step as follows:
- Preparation: Wear goggles and masks, and keep the work area clean
- Mark the cutting line: Use a marking tool to clearly mark the cutting line at the corresponding position
- Fixing ceramic tube: Using a fixture or clamp to fix the ceramic tube
- Saw blade installation: install the diamond saw blade or grinding wheel onto the cutting machine
- Start cutting: Align the saw blade with the cutting line to cut slowly, and keep steady without excessive force.
- Cooling: Use coolant to cool down while cutting to prevent overheating.
- Cleaning: Remove burrs or sharp edges, and use sandpaper to polish or carry out double-side lapping
Generally speaking, all ceramic tubes are high-temperature refractory ceramic components, the working temperature range of ceramic tubes is direct to the categories of technical ceramics, refer to the value for a few typical technical ceramic materials as follows.
- Aluminum oxide (Al2O3)
In the air: It can range from 1450℃ to 1800℃
In the vacuum state: It’s up to 2000℃
- Zirconium oxide (ZrO2)
The working temperature can reach up to 2200℃
- Silicon nitride (Si3N4)
The service temperature range is from 1000℃ to 1300℃.
- Silicon carbide (SiC)
The limit of using temperature can be from 1600℃ to 1700℃.
In conclusion, The operating temperature range of ceramic tubes depends on the type and purity of the material and is related to working conditions. When using ceramic tubes in high-temperature environments, special attention should be paid to the working temperature limit and thermal shock resistance.
