English chemist and physicist, showed that hydrogen, then called flammableair,phlogiston, or the flammable principle, was distinct from other combustible gases because of itsdensityand the amount of it that evolved from a given amount of acid and metal. In 1781 Cavendish confirmed previous observatio...
Occurrence, properties, and uses calciteCalcite, the most common form of natural calcium carbonate (CaCO3). It is a widely distributed mineral known for the beautiful development and great variety of its crystals. Calcium does not occur naturally in the free state, butcompoundsof the element are...

However, unlike tungsten, tantalum becomes brittle in hydrogen atmospheres and is therefore sintered in a high vacuum. Tantalum is without doubt the most resistant of the refractory metals and is also resistant to most acids (excluding hydrofluoric acid). ...
Molybdenum: Properties & uses Because molybdenum possesses a very high melting point, a low thermal expansion, and a high level of thermal conductivity, it is used in many different industries. Molybdenum is a genuine all-rounder. We use this material to produce products including semiconductor bas...
What are the properties and uses of chlorine? What are the properties of hydrochloric acid? What are the chemical properties of halogens? What are the physical and chemical properties of halogens? What holds the sodium and chloride ions together in a chemical bond?
This study examined the influence of graphene oxide (GO) dosage on the properties and microstructure of cement pastes against hydrochloric acid (HCl) attack. The mass loss (and sectional area loss) in 0 and 0.09 wt% GO-modified cement specimens after HCl attack were 6.1% and 4.2% (and 8%...
themineralmagnesiteand is an important source of elemental magnesium. It can be produced artificially by the action ofcarbon dioxideon a variety of magnesium compounds. The odourless white powder has many industrial uses—e.g., as a heat insulator for boilers and pipes and as an additive in...
Properties, occurrence, and uses zirconiumZirconium rod. Zirconium, obscure before the late 1940s, became a significant engineering material fornuclear energyapplications because it is highly transparent toneutrons. The element was identified (1789) inzircon, ZrSiO4(zirconium orthosilicate), from itsoxide...
