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.

Specifications of One End Closed Alumina highalumina ceramic tube

The one end shut alumina high-alumina ceramic tube is developed for high-temperature and extreme setting applications. These tubes make use of high-purity alumina raw material with over 95% Al two O ₃ web content. This makes certain solid heat resistance and chemical stability. The closed-end structure adds security for internal elements or samples.

The product comes in several sizes. Outer diameters vary from 5mm to 150mm. Wall surface density varies between 1mm and 20mm. Lengths can be personalized from 10mm to 1000mm. Temperature limitations rise to 1700 ° C for continuous use. Temporary direct exposure can handle up to 1800 ° C without contortion.

Mechanical strength is a vital feature. The tubes hold up against hefty loads and withstand bending or fracturing under stress. High density (3.6-3.9 g/cm ³) enhances performance in corrosive or abrasive settings. The smooth surface area finish decreases friction and avoids particle build-up.

Electrical insulation buildings make these tubes suitable for digital or thermal systems. They resist arc discharge and maintain insulation also at severe temperatures. Chemical resistance covers acids, antacid, and molten metals. This makes sure lasting durability in laboratories or commercial processes.

Applications include heater linings, thermocouple security, and semiconductor handling. They likewise function as insulators in burner or guards for accuracy instruments. Custom-made forms or extra machining solutions are readily available. This consists of boring side openings or including threading for safe and secure installments.

The material’s reduced thermal expansion minimizes size modifications throughout temperature level changes. This maintains systems secure in rapid home heating or cooling down cycles. Color options are conventional white or ivory. No coatings are used unless requested.

Each tube goes through rigorous high quality checks. Examinations cover dimensional precision, leak resistance, and thermal shock performance. Mass orders include protective packaging to stop damage throughout shipping. Preparations depend upon requirements however typically remain within 2-4 weeks.
