Zirconium powder is a light gray metallic powder with a density of 6.49 g/cm³ and a melting point of 1852±2°C. It easily forms an oxide film on its surface, resembling steel, and has corrosion resistance. It is insoluble in hydrochloric acid, nitric acid, and 50% sulfuric acid, but soluble in hydrofluoric acid and aqua regia. At high temperatures, it can react with various nonmetals and metal elements. Its chemical properties are active, and it can easily ignite or even explode in air, often requiring storage that is at least 25% wet to passivate it. Zirconium powder has a wide range of applications.

Rhenium powder ranges in color from gray to black and is characterized by a high melting point (3180°C), high boiling point (5627°C), and high density (21.02g/cm³). It is insoluble in hydrochloric acid but soluble in concentrated nitric acid and concentrated sulfuric acid. At room temperature, it is relatively stable in air, but it begins to oxidize when heated to 300°C, and reacts rapidly above 600°C. Powdered rhenium is easily combustible in air. It possesses very high strength, good plasticity, and ductility, making it easy to machine; however, hot processing must be conducted in a hydrogen or vacuum environment.

Vanadium powder is a silver-gray or light gray powder with a metallic luster, possessing a body-centered cubic lattice.

It is insoluble in water but soluble in nitric acid, aqua regia, and concentrated sulfuric acid. At room temperature, it is relatively stable in air, stable below 250°C, but shows significant oxidation above 300°C. At 500°C, it becomes brittle when adsorbing hydrogen. It is relatively stable in dilute sulfuric acid, dilute hydrochloric acid, and dilute phosphoric acid, exhibiting corrosion resistance. Its mechanical properties are closely related to purity and production methods, and impurities can affect its plasticity, hardness, and other characteristics.

Chromium powder is a silver-gray or black shiny metallic powder with a density of about 7.20 g/cm³, a melting point of 1857℃-1890℃, and a boiling point of 2480℃-2672℃.
