The Silicon-32, with the CAS registry number of 15092-72-5, is also known as Silicon, isotope of mass 32.  Silicon-32 is a radioactive isotope of Silicon produced by cosmic ray spallation of argon. And its half-life is about 170 years (0.21 MeV), and it decays by beta emission to ³²P (which has a 14.28 days half-life) and then to ³²S. This chemical's molecular formula is ³²Si and molecular weight is 31.9741. What's more, its IUPAC name is Silicon-32.
