ስለ Zirconium

Zirconium is a lustrous, gray-white, strong transition metal similar to hafnium. It is transparent to neutrons, making it ideal for nuclear fuel rod cladding. Cubic zirconia is a popular diamond simulant.

ፕሮግራሞች

Nuclear reactor fuel rod cladding, cubic zirconia jewelry, ceramic knives, and dental crowns.

ሐቅ

Cubic zirconia is so convincing as a diamond substitute that gemological instruments are often needed to tell them apart.
