Alumina cylindrical ceramic bracket

Aluminum oxide cylindrical ceramic bracket is an advanced industrial ceramic component made mainly from high-purity aluminum oxide (Al ₂ O3) through precision molding and high-temperature sintering. Its unique cylindrical design, combined with the inherent excellent properties of alumina ceramics, has become an ideal support, insulation, and protection solution for many high temperature, high pressure, high wear, and harsh electrical environments. This product plays an irreplaceable role in the fields of semiconductors, photovoltaics, new energy, medical equipment, and scientific research instruments due to its excellent reliability, stability, and long lifespan.

Core product advantages: Why is alumina ceramic the ideal choice?

1. Excellent high temperature resistance:
   It can work stably in high temperature environments above 1600 ℃ for a long time, with a small coefficient of thermal expansion and excellent thermal shock resistance. It can withstand severe temperature changes without cracking.
2. Extremely high mechanical strength and hardness:
   It has high hardness (Mohs hardness can reach level 9, second only to diamond) and excellent compressive strength, capable of withstanding heavy loads and strong impacts, with a wear life far exceeding that of metal and plastic materials.
3. Excellent electrical insulation performance:
   High resistivity and low dielectric loss make it an ideal high-temperature insulation material that can maintain stable insulation properties even in high temperature and high-frequency environments.
4. Excellent chemical stability:
   It has strong corrosion resistance to most acids, bases, and molten metals, is not easily oxidized, and can be used for a long time in corrosive environments without being corroded.
5. Precise size and stability:
   Through advanced molding and sintering processes, we can achieve strict dimensional tolerance control and extremely high surface smoothness. The product has minimal deformation during long-term use, ensuring precise and reliable equipment operation.

Key problems solved and application areas
The alumina cylindrical ceramic bracket is specifically designed to solve the problem of traditional materials (such as metal, ordinary plastic, or other ceramics) failing under extreme working conditions.
It can effectively solve:
Deformation and softening at high temperatures: replacing plastic or metal brackets that are not resistant to high temperatures.
Insulation failure risk: Provide reliable insulation in high-voltage and high-frequency circuits to avoid breakdown.
Short lifespan caused by wear and corrosion: significantly extending equipment maintenance cycles in frictional or corrosive environments.
Polluting products or environment: non-magnetic and non-volatile, avoiding pollution to precision manufacturing processes such as semiconductors and photovoltaics.

Main application areas:
Semiconductor manufacturing: used as wafer sintering support, diffusion furnace support, CVD equipment fixture to ensure the purity and flatness of chips during high-temperature processing.
Photovoltaic industry: used as a key support component for conveying rollers in solar cell sintering furnaces.
New energy and lithium batteries: used for insulation and support of lithium battery sintering furnaces and fuel cell testing equipment.
Medical and analytical instruments: used as insulation brackets and positioning components inside high-precision equipment such as X-ray tubes, vacuum chambers, and mass spectrometers.
Industrial furnaces and heat treatment: used as kiln furniture and support columns for firing plates in high-temperature furnaces, carrying workpieces and withstanding long-term thermal cycles.

Customer real case (anonymous)
Customer background: A leading semiconductor equipment manufacturer.
Problem encountered: The customer encountered slight deformation and crystallization of the original quartz bracket in their new generation diffusion furnace under long-term high-temperature cycling at 1400 ℃, resulting in a decrease in the flatness of the silicon wafer carried and affecting product yield.
Our solution: We have customized and developed a 99.5% high-purity alumina cylindrical ceramic bracket for it. By optimizing the formula and sintering curve, the product has achieved superior thermal shock resistance while ensuring extremely high temperature strength.
The achieved effect: After the new bracket was put into use, there was no deformation or performance degradation in production for more than 12 months. The flatness of the silicon wafer was significantly improved, and the maintenance cycle of the customer’s equipment was extended by more than three times, effectively reducing the comprehensive operating cost and gaining high recognition from the customer.
