Tungsten steel
Tungsten or Wolfram is a very hard, heavy metal and is one of the densest elements on the periodic table, weighing in at 19.3. It is a transition metal, which means that it has some of the properties common to many metals.
Tungsten gets its name from the Swedish words tung sten, which mean heavy ......
Niobium tantalum uranium ore
Molybdenum and tungsten are two of the most important materials used in manufacturing today and are essential for a range of industrial and commercial applications. Molybdenum, often referred to as ‘moly’, is a hard, corrosion-resistant metal alloy and is commonly found in the form of molybdenum......
vein quartz
Quartz is one of the most plentiful and versatile minerals on the earth. It is found in a wide variety of geological environments, from hot springs to volcanoes, from meteors to deep-sea hydrothermal vents. Quartz has been a popular material for jewelry and other ornamental objects for centuries. ......

Silica
Silica is a precursory mineral for other minerals in the environment due to its physical and chemical properties. It is one of the most abundant materials in the Earth’s crust, constituting roughly 25-percent of the total mineral content. Although much of it is bound in rocks, it can also......
Potassium feldspar
Potassium feldspar is one of the most abundant minerals on the Earths crust and it is an essential part of many igneous rocks. It is composed primarily of potassium, sodium, calcium and aluminum, with a relative abundance of silicates which play a major role in the formation of feldspars. Potassiu......
shallow grain rock
Granite and Gneiss are two of the most common types of igneous rocks.Granite is a coarse-grained intrusive igneous rock with a medium to high level of silica. It typically has quartz grains, plagioclase feldspar, hornblende, biotite, and muscovite. With proportions roughly equal of plagioclase and......
