12005-21-9 Usage
Uses
Used in Gemstone Industry:
Yttrium Aluminum Oxide is used as a diamond imitation for various applications, including jewelry and decorative items. It is known under trade names such as Diamonaire, Diamonique, Diamonite, Kimberly, Triamond, and YAlG for YAG, and Diamonique II, Galliant, and Triple G for GGG. However, it has been largely replaced by cubic zirconia due to its superior properties.
Used in Laser Technology:
Rare earth element-doped Yttrium Aluminum Oxide is used in solid-state lasers, where it serves as a host material for various laser-active ions. This application takes advantage of its excellent optical properties, high thermal conductivity, and chemical stability.
Used in Electronics:
Yttrium Aluminum Oxide is used in the form of a 99.99% pure material as a sputtering target to prepare bubble memory devices. This application utilizes its high purity, high melting point, and excellent chemical stability to ensure the production of high-quality electronic components.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 12005-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12005-21:
(7*1)+(6*2)+(5*0)+(4*0)+(3*5)+(2*2)+(1*1)=39
39 % 10 = 9
So 12005-21-9 is a valid CAS Registry Number.
