Introduction to Alumina Ceramics

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 Alumina Ceramics

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.

5 FAQs of Low-cost Alumina Ceramic Raw Material Powder – Refractory Castable, Spot Whole with Large

What is this low-cost alumina ceramic powder?
It’s a raw material powder. Manufacturers use it to make refractory castables. This powder has high alumina content. Its cost is lower than many alternatives. This makes it budget-friendly.

Why choose this specific powder?
Price is the main advantage. It offers significant savings. Quality remains good for many applications. It provides reliable heat resistance. Durability meets standard requirements. Performance is solid without the high cost.

What does “Spot Whole with Large” mean?
This refers to the particle size distribution. “Spot whole” means particles are present across various sizes. “Large” indicates a good portion are bigger particles. This mix helps packing density. Better packing means stronger castables after firing. It reduces shrinkage too.

How is this powder used in castables?
You mix the powder with other components. These include binders and additives. Water is added to form a workable castable slurry. The slurry is poured into molds. It sets and hardens. Then it’s fired at high temperature. The alumina powder forms the main refractory structure.

Any special storage or handling needs?
Keep the powder dry. Moisture ruins its flow and performance. Store bags in a covered, dry warehouse. Use sealed containers if opened. Avoid contamination from dirt or other materials. Wear a dust mask during handling. Powder dust can irritate lungs.
