Thorium Resources | Chem230 Wiki | Fandom
Thorium was discovered in 1828 by the Norwegian mineralogist Morten Thrane Esmark and was identified by the Swedish chemist Jons Jakob Berzelius. It was named after Thor, the Norse god of thunder. Thorium is found in small amounts in most rocks and soils; it is about as common as lead. Soil commonly contains an average of around 6 ppm of thorium. Thorium occurs in several thorium …

75 uses of thermal energy in daily life - All Uses of
Many Industrial products such as paper and paperboards need a high amount of thermal energy that comes from burning wood, which produces the required heat. 7. Steam cleaners burn wood to produce heat, which is used to heat water past the boiling point.
Ammonia - Wikipedia
Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.

Cryptocrystalline magnesite - Department for Energy and …
The presence of boron in MgO is undesirable for refractory products as it reduces the melting point and lowers performance under high-temperature operation. Boron adsorption can be reduced to <300 ppm in MgO product by over- seawater to increase the pH, but this needs to be balanced with the tendency for excess calcium to precipitate with Mg(OH) 2 (Shand 2006).

This reveals that 50 g of apatite concentrate will produce 28.9 g of final calcined slag, i.e., CaO not Ca(OH) 2, and 0.62 g of ferrophosphorus. The balance of the mass, i.e., 20.5 g, is assumed to have reported to the gas phase during the pre-calcination step, as well as during the final reaction.
Magnesium | Geoscience Australia
When calcined magnesia is heated to between 1530 —2300 C, the product produced is non-reactive and exhibits exceptional stability and strength at high temperatures. This product known as ''dead-burned'' or ''sintered'' magnesia is mainly used as a refractory material because of its inertness and high melting point.
