Melt Crystallized Molybdenum Crystal
From(the seller): LSPOsmium TetraoxideA very rare crystal obtained through melting, which is oxidized to give it a unique color
From(the seller): LSPOsmium TetraoxideA very rare crystal obtained through melting, which is oxidized to give it a unique color
From(the seller): MingLing (above), Mini chemical library (below)Osmium TetraoxideTwo tungsten crystal rods doped with some other metal; these crystals are deposited during long-term heating processes
From(the seller): Leibizhenqi三点 测娇Thin flake chromium crystals prepared by molten salt electrolysis method are different from common electrolytic chromium samples. This type of chromium surface has unique patterns and also connects some small crystals with octahedral structures. It can be considered a slightly rare sample
From(the seller): metal recycler三点 测娇A tungsten sample. I don’t know the specific preparation method for this sample yet, perhaps it is physical vapor deposition method? Tumor like tungsten particles grown on small discs of pure tungsten. This is a common, inexpensive, and interesting sample
From(the seller): Pavel ChernovBin XiangSome small and delicate electrolytic chromium crystals with marvelous shapes. The edges are sharp and clear, and without any oxidation.
From(the seller): CCCP InstituteBin XiangA pure molybdenum single crystal, the overall quality is very good, it is an old sample from the Soviet era. Unfortunately it is not complete, half of it has been cut off.
From(the seller): wowo tou三点 测娇Chromium crystals prepared by chemical vapor deposition method have a faint blue luster, beautiful crystal appearance, and octahedral structure can also be observed. Although this crystal is expensive
Tungsten (left) and molybdenum (right) prepared by physical vapor deposition method are said to be produced by long-term use of tungsten crucibles for sublimation in a vacuum high-temperature environment in sapphire production plants. Distributed to element collectors through some metal recyclers. This is an easily obtainable but very interesting sample, however, the purity of the …
Molybdenum, a metal produced by regional melting, has large defective polycrystalline rods and small single crystal rods, which have a certain degree of oxidation due to improper storage environment
Tungsten metal prepared by physical vapor deposition method is a crystal with bright luster, which was mistakenly believed to be prepared by molten salt electrolysis method in the past. It is said that in order to produce this batch of tungsten crystals, expensive equipment was scrapped due to operational errors, which can be said to …
From(the seller): Tom.1967Date: 2023/10Bin XiangThis perfect chrome specimen is a pleasure to look at. It is an ultra-high purity chromium sample obtained using chemical vapor deposition. Its purity reaches 99.999+%, far exceeding the electrolytic chromium or ordinary metallurgical materials we usually use. This huge sample weighs more than 200 grams. It is undoubtedly a very …
From(the seller): CCCP InstituteDate: 2024.2Xiang BinA very rare single crystal tungsten produced by zone refining. It is very special and comes with a quality inspection report indicating its origin and possible year. As far as we know, high-end materials such as single crystal tungsten are usually specialized supply commodities and are used in key scientific …
