  • It gives steady results in tough places.

Key Properties of 95% Alumina Ceramic

Main Applications of 95% Alumina Ceramic

Mechanical Strength & Hardness

Alumina ceramics are strong and tough. 95% alumina has good mechanical strength. This makes it great for factories and machines. The table below shows how strong and hard it is compared to high purity alumina:

This strength helps alumina ceramics work in hard jobs. They are used in turbine blades and furnace linings. You also see them in other strong ceramic parts. Yield strength helps these materials keep their shape. They do not bend or break in tough places.

Electrical Insulation

Alumina ceramics are great at stopping electricity. Their electrical resistivity is about 10^14 Ohm·cm. This means electricity cannot pass through easily. That is important for many electronic devices. Here are some ways they are used:

  • Spark plug insulators

  • Integrated circuit packages

  • Power electronics

  • Microwave components

  • Ceramic-to-metal feedthroughs

  • X-ray component feedthroughs

  • High-voltage bushings

  • Medical implants

People use alumina ceramics in these products for strong insulation. They also want steady performance. High-purity alumina ceramics work well in high-voltage and high-frequency places.

Chemical & Thermal Resistance

Alumina ceramics do not get damaged by acids or alkalis. They can be used with strong chemicals and do not corrode. These ceramics also work at very high temperatures. They can handle up to 1600°C. This makes them good for furnace tubes and pump parts. They are also used in other hard jobs. High-purity alumina ceramics stay strong and keep their shape. They do not change when heated or put in chemicals.

Tip: If you need something for high heat or chemicals, alumina ceramics are a smart choice for many factories.

You can see why 95% alumina is used in many things. It is found in electronic substrates, mechanical seals, and wear-resistant linings. It works well and does not cost too much. That is why people pick it for many 95% alumina ceramic uses.

Applications of 95% Alumina Ceramic

Main Applications of 95% Alumina Ceramic

You can find 95% alumina ceramic in many places. Many industries use it because it is strong and resists heat and chemicals. It also stops electricity from passing through. Let’s see where people use alumina ceramics and why they pick them.

Electronic Substrates & Components

Alumina ceramic is used in electronics for parts and boards. These boards help move heat away and keep circuits safe. Alumina ceramic gives strong insulation and lets heat move out. You find it in circuit boards, LED lights, and power modules. Aluminum oxide ceramic keeps its shape and size when it gets hot or cold. This is important for making chips and laser machines. Devices work well and last longer because of this.

Note: In electronics, alumina ceramic is used for spark plug insulators, microwave parts, and high-voltage bushings. These need strong insulation and steady work.

Mechanical Seals & Precision Parts

Alumina ceramics are used in seals and small machine parts. These seals are found in pumps, valves, and compressors. Aluminum oxide ceramic is very hard and does not wear out fast. This means the parts last longer and need less fixing. You also save energy. The table below shows how alumina ceramic helps in different jobs:

Application Area

Performance Improvements

Machinery manufacturing

Longer service life, energy savings

Aerospace

Lasts longer in tough places

Precision instruments

Better at stopping wear and rust

Petrochemical

Handles high heat

Textile machinery

Very strong

Electrical appliances

Safe and easy to control

Refrigeration equipment

Good for the environment

Chemical industry

Insulates well

Communications

Works well in hard conditions

You also see aluminum oxide ceramic in fast bearings and air valves. These need to be tough and not rust. Alumina ceramics keep their shape and size, so they are good for measuring tools.

Wear-Resistant Linings & Coatings

Alumina ceramic is used to line and coat machines in mining and factories. These liners protect machines from wearing out and breaking. Alumina ceramic parts last much longer than metal or plastic ones. Here are some facts:

  • They last 266 times longer than manganese steel and 171.5 times longer than high-chromium iron.

  • Round shapes help stop breaking.

  • They are used in bucket wheels and coal chutes.

Alumina ceramic liners mean you fix machines less often. They are tough, resist wear, and last a long time. You save money because you do not need to fix things as much.

Pump Accessories & Structural Parts

Aluminum oxide ceramic is used in pump parts and strong machine pieces. These need to handle heat, pressure, and wear. Ball valves, piston pumps, and deep drawing tools use alumina ceramic because it is tough. These parts last a long time and look smooth. The material does not soak up water or get damaged by chemicals. It works well in hot places and keeps friction low.

  • Liquid parts stay clean and work well.

  • You can clean and sterilize them easily.

  • They do not soak up water or let out particles, so they protect sensitive jobs.
