Allgemeine Beschreibung
Aluminum oxide (Al2O3), also known as alumina. It is commonly used in various rubber, plastics, ceramics, and refractory materials for reinforcement hardening. It can also be used as a filler or component in polymer or inorganic composite materials, as a catalyst or catalyst support, as an adsorbent, etc.
Anwendung
Aluminum oxide is used as
- Filler for plastics and a common ingredient in sunscreen and many cosmetics.
- As a catalyst for alcohol dehydration in the Claus process.
- As a catalyst in the conversion of urea to ammonia.
Leistungsmerkmale und Vorteile
Aluminum oxide has:
- High porosity
- High surface area
- Acidic and basic property

Water-based drilling fluids are extensively used for drilling oil and gas wells. However, water-based muds cause clay swelling, which severely affects the stability of wellbore. Due to two adsorption positions, it is expected that cationic gemini surfactants can reduce the

We demonstrated a promising route for enhancing temperature sensitivity, improving saturation voltage, and reducing power consumption of the MOS(p) tunneling temperature sensors by introducing ultrathin Al2O3 into the dielectric stacks. Detailed illustrations of the working mechanism and device concept are
