Introduction to China Calcined Alumina/Aluminum Oxide for Ceramics Polishing Products, CAS 1344-28-1

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of China Calcined Alumina/Aluminum Oxide for Ceramics Polishing Products, CAS 1344-28-1

Specifications of China Calcined Alumina/Aluminum Oxide for Ceramics Polishing Products, CAS 1344-28-1

China calcined alumina is aluminum oxide powder. It is also known as calcined aluminum oxide. Its CAS number is 1344-28-1. This material is very hard. It is perfect for polishing ceramic products. Manufacturers use it widely.

This alumina is made in China. It undergoes high temperature treatment. This process is called calcination. Calcination changes the crystal structure. It makes the powder harder. It also improves chemical stability. The powder resists acids and alkalis better. This is important for polishing applications.

Particle size is critical. We offer various particle sizes. Common sizes are F220, F320, F400, F600, F800, F1000, F1200. Finer particles give smoother finishes. Coarser particles remove material faster. You choose the size based on your polishing stage. Initial grinding needs coarser powder. Final polishing needs finer powder.

The purity is very high. Typically, the Al2O3 content is 99.5% or higher. High purity means fewer impurities. Impurities can scratch the ceramic surface. They can cause defects. Our powder ensures a clean, bright polish.

The powder has a sharp angular shape. This shape helps cutting the ceramic surface. It removes material efficiently. It creates a uniform polish. The hardness prevents the particles from breaking down too fast. The particles stay effective longer.

This alumina meets industry standards. It follows GB/T or other relevant specs. Consistency is guaranteed. Batch after batch performs the same. This reliability is essential for production.

It is used for polishing many ceramics. Examples include tiles, sanitaryware, tableware, technical ceramics. It works on porcelain. It works on stoneware. It works on advanced oxide ceramics. The results are excellent surface quality. It delivers high gloss finishes. It minimizes surface flaws.

You can use it in different polishing machines. It is compatible with many polishing compounds. It is a key material for ceramic finishing.

Applications of China Calcined Alumina/Aluminum Oxide for Ceramics Polishing Products, CAS 1344-28-1

China calcined alumina is aluminum oxide. This material is very hard. It works well for polishing ceramics. The chemical name is aluminum oxide. The CAS number is 1344-28-1. Calcined alumina comes from heating alumina hydrates. This heating removes water. It creates a strong, stable powder. The powder has high purity. It is very consistent. These qualities matter for polishing.

Calcined alumina particles are tough. They are sharp. This makes them cut ceramic surfaces smoothly. Manufacturers control the particle size carefully. Fine particles give a smooth finish. Coarser particles remove material faster. The powder does not break down easily. It stays effective during polishing. It does not react badly with the ceramic. This keeps the ceramic color true.

Ceramic polishing uses alumina in different ways. It goes into polishing powders. It goes into polishing pastes. It goes into grinding wheels. Many ceramic items need polishing. These include tiles. These include sanitary ware. These include tableware. These include technical ceramics. Factories use alumina for polishing. Labs use it too. It helps get a shiny surface. It helps get a precise shape.

China makes lots of calcined alumina. The quality is good. The price is competitive. Buyers worldwide use it for ceramic products. It is a reliable choice for finishing.

5 FAQs of China Calcined Alumina/Aluminum Oxide for Ceramics Polishing Products, CAS 1344-28-1

What is calcined alumina?
Calcined alumina is aluminum oxide treated with high heat. This heat changes its structure. It becomes harder and more stable. It is a white powder. People use it for polishing ceramics.

Why use calcined alumina for polishing ceramics?
Ceramics are hard materials. They need a hard material to polish them. Calcined alumina is very hard. It cuts the ceramic surface smoothly. It removes surface imperfections. It creates a shiny finish. Other materials might be too soft. They might not work as well.

How does calcined alumina compare to other polishing materials?
Calcined alumina offers a good balance. It is hard enough for effective polishing. It is not too aggressive. Some materials cut too fast. They can scratch the ceramic. Others cut too slowly. They take too much time. Calcined alumina provides efficient, controlled material removal. This makes it popular.

Why is particle size important in calcined alumina?
Particle size directly affects the polish result. Smaller particles create a finer finish. Larger particles remove material faster. They leave a rougher surface. Choosing the right particle size is crucial. It depends on the desired final look. Manufacturers offer different sizes for different polishing steps.

How do manufacturers ensure consistent quality?
Good suppliers control their production process carefully. They use pure raw materials. They manage the calcination temperature and time precisely. They test the product thoroughly. They check the chemical purity. They measure the particle size distribution. They confirm the hardness. Consistent quality means reliable polishing performance every time.
