High Mountains and Flowing Waters
- Tantalum&Niobium Series
"High mountains and flowing waters" in ancient Chinese story are a metaphor for the relationship between bosom friends. T&N is an acronym for the element symbol tantalum (Ta) and niobium (Nb). Taken together, the two symbols indicate that when once bosom friends meet in their life, they cannot be separated from each other, as like as niobium in tantalum and tantalum in niobium.
Because:

High Mountains and Flowing Waters
- Tantalum&Niobium Series
"High mountains and flowing waters" in ancient Chinese story are a metaphor for the relationship between bosom friends. T&N is an acronym for the element symbol tantalum (Ta) and niobium (Nb). Taken together, the two symbols indicate that when once bosom friends meet in their life, they cannot be separated from each other, as like as niobium in tantalum and tantalum in niobium.
Because:
- Tantalum and niobium belong to the same group in the periodic table of elements and are both refractory metals in rare metals. Because they have very similar physical and chemical properties, and their distribution in nature is often co-existing and inseparable, early chemists once mistakenly believed that they were the same element. It was not until 1844 that German chemists successfully separated tantalum and niobium for the first time that the twin brothers of the metal world were able to distinguish each other.
- Tantalum and niobium have good physiological corrosion resistance and biocompatibility, so they are often used as body implant materials and surgical tools, such as bone plates, bone screws, implant teeth, roots, scalpels, and so on.
- Tantalum and niobium resource reserves are scarce, and their price in rare metals is above the medium level. Due to the similar properties of tantalum and niobium, which are symbiotic and difficult to separate, tantalum and niobium have become the symbol of "close and intimate friends". The T&N series represents the joy of meeting close friends and the invaluable value of friendship.
