Crystalline bulk silicon is relatively inert but becomes more reactive at high temperatures. Still, the formation of the vitreous dioxide rapidly increases between 950 °C and 1160 °C, and when 1400 °C is reached, atmospheric nitrogen also reacts to ...…
What is Silicon powder?Silicon powder, known as micronized silicon, is used for many applications. Metallurgical silicon is typically produced in a size of 0-100 mm, but further size reduction is required for most applications. The optimum particle s...…
The beginnings of the revolutionary froth flotation process are associated with graphite mining. The E&MJ article on the Dixon Crucible Company includes a sketch of the “floating tanks” used in the age-old method of extracting Graphite. Because Graph...…
What is Graphite?Graphite’s extreme softness, greasy feel, low specific gravity, and the ease with which it leaves dark grey to black marks on paper usually distinguish it from similar-looking metallic minerals. Its name comes from the Greek word ‘gr...…
These sulfides are relatively inert, dissolve into acid, and are insoluble in water and alkalis. Zinc sulfide causes flaming decomp /of hydrazinium nitrate / above the melting point (70 °C). / Hydrazinium nitrate: alone, etc/ The reaction between iod...…
ZnS has a unique structure type compared to other molecules, having different types of individual structures. ZnS can have a zinc blende struck, ais a "diamond-type net, "or rk", and at a different temperature, ZnS can become the wurtzite structure w...…
Some types of SiO2 employed for industrial purposes include high-purity α-quartz, vitreous silica, silica gels, and diatomaceous earth. Very pure quartz crystals in oscillators and other electromechanical devices constitute one of the most critical a...…

The earliest routes to elemental boron involved the reduction of boric oxide with metals such as magnesium or aluminum. However, the product is almost always contaminated with borides of those metals.[citation needed] Pure boron can be prepared by re...…
Boron is a chemical element with the symbol B and atomic number 5. Its crystalline form is a brittle, dark, lustrous metalloid; in its amorphous structure, it is a brown powder. As the lightest element of the boron group, it has three valence electro...…
During processing and qualification, packages are subjected to significant temperature changes. A thermal cycling test is commonly applied for reliability qualification to determine the ability of components and interconnects to withstand mechanical ...…
What is copper oxide?Copper and Oxygen, when combined, form magnetic materials, including copper oxide (I) and copper oxide (ll); both minerals are found in nature and have unique characteristics and particular uses. Copper oxide (II), or cupric oxid...…
Nanotechnology is the study of small materials. They are made of tiny particles and can be made into various products and structures. Some of these materials are used in consumer products.…
The analysis of the thermal conductivity dependency on the density detects the linear fit as a best-fitting curve for the considered range of FC densities. The coefficients of the linear fit are depicted. Exceptionally high values of the coefficient ...…
What is graphite?Graphite is a naturally occurring modification of carbon (chemical formula: C). Its atoms arrange themselves in the hexagonal pattern, which is typical for carbon, and thus form a hexagonal layered lattice. Graphite gets its typical ...…
