Premium Alumina Oxide Ceramic Insulator - Customizable Industrial Ceramic for Extreme Wear and Corrosion Resistance

With its remarkable ceramic wafer chucks, UNIPRETEC CERAMIC leads the complex world of semiconductor manufacturing, reliably and precisely establishing industry standards. These chucks, which are made of carefully chosen materials including alumina (Al2O3), silicon carbide (SiC), and silicon nitride (Si3N4), are remarkably strong mechanically and thermally. They are essential to maintaining the accuracy and stability of wafer processing and have shown unmatched dependability under the harsh circumstances that are part of the production process.

Chemical resistance built into UNIPRETEC CERAMIC's ceramic wafer chucks protects the wafers from contamination by preventing the corrosive effects of acids and solvents. In procedures needing electrical insulation, including radiofrequency plasma applications, their high dielectric strength and low outgassing properties are essential. Because these chucks grip wafers precisely, photolithography and other procedures are more accurate. Chemical inertness further lowers contamination and guarantees semiconductor device cleanliness.

Wear resistance and durability are characteristics of ceramic wafer chucks made by UNIPRETEC CERAMIC. They not only lessen the need for replacements but ultimately save manufacturers a great deal of money. Right cleaning and upkeep are necessary to keep these benefits. Important first measures in maintaining chuck performance are to gently wipe the chuck surface with a dust-free cloth or professional cleaning equipment and to routinely do thorough cleanings, including using ultrasonic cleaners or high-pressure air guns to reach difficult-to-reach places.

Basic yet essential maintenance procedures are making sure all moving parts are properly lubricated, looking for loose fasteners, and making sure electrical connections are solid. Furthermore essential are routine environmental management and accuracy calibration, as well as expert maintenance for intricate servicing requirements. With their dependable and consistently high performance ceramic wafer chucks from UNIPRETEC CERAMIC are a vital component of the semiconductor manufacturing process.

What’s the advantage of aluminum oxide ceramic?

- Excellent thermal stability;

- Outstanding dielectric characteristics;

- High mechanical strength;

- Non-magnetic.

What’s the disadvantage of aluminum oxide ceramic?

The reason aluminum oxide ceramics cost more to manufacture than metal materials is mostly because of the high cost of raw materials, difficult manufacturing, and complex procedures. Costs of manufacture therefore limit the application of aluminum oxide ceramic in specific industries.

Aluminum oxide ceramics are brittle even though they are quite hard; they can fracture under strong impact or distortion. As so, there are some safety concerns associated with the application of aluminum oxide ceramic in some fields.

Toughness of ceramics made of aluminum oxide is rather poor. They are unable of withstanding severe temperature swings and show little thermal shock tolerance.

How hot can aluminum oxide ceramic be operated at?

Aluminum oxide ceramics are mostly advantageous because of their excellent high-temperature stability. Many materials cannot match its remarkable performance even in extremely hot conditions. Aluminum oxide ceramics are normally resistant to temperatures between 1300 and 1700° C. It can resist higher temperatures the higher its alumina concentration.

Can ceramic made of aluminum oxide conduct electricity?

All things considered, aluminum oxide ceramic is an insulator rather than a conductor. Its outstanding ability to insulate electrically makes it useful in many different applications where electrical insulation is crucial. This characteristic results from the way its covalent and ionic bonds are arranged, which prevent electric current from flowing freely.

Are ceramics made with aluminum oxide porous?

The exact makeup, production techniques, and intended application of aluminum oxide ceramic can all affect its porosity. Generally speaking, high-purity alumina ceramics are thick and have comparatively little porosity. These ceramics find wide use in applications requiring high mechanical strength, hardness, and wear resistance.

Nevertheless, specific alumina ceramics can be deliberately engineered to reach controlled porosity values. One can make porous aluminum oxide ceramics by adding specific additives or by using specific production methods. Sometimes adding porosity on purpose might increase thermal insulation, lighten a material, or increase the particular fluid permeability for a certain use.

Ceramic made of aluminum oxide is heavy?

Aluminum oxide ceramic is not particularly heavy in relation to many other technical materials. Specific density of aluminum oxide ceramic, Al2O3, is approximately 3.95 g/cm³. It is lighter than many metals, yet not as light as some polymers or foams. When maximizing weight is not as crucial as combining qualities like electrical insulation, high hardness, and wear resistance, aluminum oxide ceramic is often chosen for use.

Will ceramics made with alumina become yellow?

Usually white or colorless, alumina ceramics can turn yellow with time if they are exposed to UV light, high temperatures, or specific chemicals on a regular basis. This color shift may change its appearance, but it usually has little impact on the structural soundness or operational effectiveness. Even with fading, the chemical and mechanical properties of alumina ceramics remain same. These aspects could be considered while selecting and creating materials to ensure their durability and attractiveness over time as well as to prevent or reduce the frequency of color changes.

Is ceramic with alumina toxic?

Generally considered to be non-toxic and biocompatible, it finds application as a high-performance material in the electrical, medical, and industrial sectors. Dental implants and prosthetic joints are two medical applications for alumina ceramics, which are so safe for human flesh. Moreover proving its chemical stability and safety is its application in the electronics industry as an insulating material. But just as any material, alumina ceramics can change in reaction to specific conditions, such as high heat or chemical reactions. But in ordinary use and contact scenarios, alumina ceramics are a reliable and safe material.
