Why Is The Tungsten Rod So Powerful?

2024-01-05 18:00:06

Tungsten after smelting is a silver - white shiny metal with high melting point and hardness. Atomic number 74. It is free from air erosion at normal temperature and has high density.


These high-density tungsten rods, guided by satellites, can use the tremendous kinetic energy generated by small rocket propellants and free fall to deliver rapid, precise strikes against high-value strategic targets anywhere on earth at any time.

Introduction to types of tungsten:

There are more than ten kinds of tungsten ore, and there are two kinds in China. Wolframite (ferromanganese) and scheelite (calcium tungstate).


Wolframite (FeMn)WO4. Color has dark gray, reddish brown, light brown black, hair brown and iron brown and other colors. Semi-metallic luster, metallic luster and resin luster. It is usually foliate, curved sheet, granular and dense. In addition, some monoclinic crystals, such as thick plate and pointed column, are often filled in granite and its nearby rock cracks in the form of veins together with white quartz. Hardness 5-5.5, specific gravity 7.1-7.5. Jagged fracture. The sex is brittle, have weak magnetism. Wolframite is the main raw material for refining tungsten and producing tungstate.


Scheelite caw 4. Color is off-white, also have yellow brown, green and pink. Grease sheen. It belongs to the tetragonal system, forming a bipyramidal pseudooctahedron or plate crystal, crystal plane sometimes oblique stripes, the intercalated twin is more common. Some crystals are crustlike, renal, granular and dense lumps. Hardness is 4.5 5; The proportion of 5.9 6.2. Brittle, shell - shaped or staggered fracture. Scheelite produces a beautiful light blue glow when exposed to fluorescent lamps. Scheelite ore is produced in dayu, jiangxi, rucheng, anhua, linwu, wenshan, yunnan, etc.
