Used in Optical and Electronic Non-Volatile Memories:
Germanium telluride is recognized as a prototypical phase change material of high interest for its use in optical and electronic non-volatile memories, making it a valuable component in data storage technology.
Preparation
Germanium telluride is produced by heating Ge (less resistivity) and Te (99.998%) to their melting points in an evacuated quartz tube. single crystals can be obtained using the zone melting method.
Check Digit Verification of cas no
The CAS Registry Mumber 12025-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,2 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12025-39:
(7*1)+(6*2)+(5*0)+(4*2)+(3*5)+(2*3)+(1*9)=57
57 % 10 = 7
So 12025-39-7 is a valid CAS Registry Number.
