FAQ

What are the physical and chemical properties of attapulgite (CAS: 12174-11-7)?

Attapulgite (CAS: 12174-11-7) is a naturally occurring hydrated aluminum silicate with a layered or smectite structure. It is characterized by a high specific surface area and low density. Attapulgite has a high whiteness and is insoluble in water and common organic solvents. It is chemically inert and exhibits low reactivity, making it suitable for various applications due to its adsorption and rheological properties.

How is attapulgite (CAS: 12174-11-7) typically synthesized?

Attapulgite is not typically synthesized but is obtained from natural deposits. However, it can be processed from kaolinite and other clay minerals through a series of steps including washing, milling, and heat treatment to enhance its properties. The processing methods can vary depending on the desired outcome and the specific clay source.

What industries use attapulgite (CAS: 12174-11-7)?

Attapulgite (CAS: 12174-11-7) is widely used in various industries. It is commonly found in pharmaceuticals, where it acts as a carrier for active ingredients, in polymers as an additive to improve mechanical properties, in sensors for its adsorption capabilities, and in semiconductors for its thermal and electrical conductivity.

What precautions should be taken when handling attapulgite (CAS: 12174-11-7)?

When handling attapulgite (CAS: 12174-11-7), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be handled carefully using appropriate absorbent materials, and the area should be cleaned with water and a detergent. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
