From(the seller): canyue & wowotou三点 测娇Niobium crystals prepared by molten salt electrolysis method. Unlike other niobium samples, this niobium sample is in the shape of a hollow tube. This is because the niobium crystal of this sample was deposited on the niobium wire (while most niobium crystals were deposited on thin sheets)
From(the seller): Champagne & xiao jun三点 测娇Two single crystal niobium rods prepared by regional melting method, one of which has a large hollow in the middle (possibly used for other purposes), are both from Russia. These metal rods have beautiful patterns. It is a relatively rare and expensive sample
From(the seller): wowo tou三点 测娇Another type of niobium crystal produced by molten salt electrolysis has two subtypes, one resembling a ladder and the other resembling a shuttle. The former is a parallel connected crystal of a cube, while the latter is a parallel connected crystal of a cube with interlaced twin crystals. It is said …
From(the seller): canyue三点 测娇A type of niobium crystal produced by molten salt electrolysis, with a rhombic dodecahedral or hexagonal prism structure, which is of the same type as crystals on niobium crystal strips. It is said to come from a Soviet factory in the last century. (I’m not sure about the specifics, anyone who knows …
Metal niobium prepared by molten salt electrolysis method.Unlike most electrolytic niobium crystal samples, the crystal of this sample has rare cubic and tetrahedral structures.The surface appears very rough, and upon magnification, the crystal growth patterns can be observed, which can be used to explore the process of crystal growth.
