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 99.8% Alumina square ceramic crucible

The 99.8% alumina square ceramic crucible is developed for high-temperature applications requiring stability and toughness. It is made from premium-grade alumina ceramic with a pureness degree of 99.8%, making sure marginal contaminations for constant performance. The square form gives efficient room application in heaters and kilns, fitting basic configurations without lost voids.

The crucible operates in temperatures up to 1750 ° C continuously and withstands short-term heights of 1800 ° C. This makes it suitable for thawing metals, sintering sophisticated ceramics, and handling glass or chemicals. Its high thermal conductivity makes sure even warm distribution, reducing hotspots that might damage examples.

Chemical resistance is an essential feature. The material resists acids, antacid, and molten salts, maintaining structural integrity in destructive environments. This permits repeated use in hostile procedures without destruction. The reduced porosity of the alumina ceramic stops contamination, essential for applications like semiconductor processing or analytical laboratories.

Mechanical strength is focused on. The crucible has a thick structure with a solidity ranking of Hv 1500, standing up to scrapes and abrasion throughout handling. Its square edges are precision-machined to stop damaging, expanding service life. The design includes somewhat rounded corners to decrease tension focus during fast temperature changes.

Criterion sizes range from 10mm x 10mm x 10mm to 150mm x 150mm x 150mm, with custom measurements offered. Wall thickness options range 2mm and 10mm, balancing thermal effectiveness and load capability. Surface area surfaces include as-sintered or sleek, with refined variations minimizing material adhesion for less complicated cleansing.

The crucible deals with induction heating, resistance home heating, and gas-fired systems. It is compatible with platinum, non-ferrous metals, and rare planet materials. Customers need to prevent abrupt temperature shifts going beyond 300 ° C per min to avoid cracking. Pre-heating at 500 ° C for thirty minutes before high-temperature usage is recommended.

Handling needs dry conditions before heating up to prevent steam-related fractures. Storage should remain in moisture-free environments. The product is packaged individually in shock-absorbent products to prevent transportation damages. Regular sectors using this crucible consist of aerospace, metallurgy, research labs, and electronics manufacturing.
