Spodumene is a mineral with an important role to play in modern ceramics: the addition of resistance to thermal shock and expansion - making for a longer ceramic lifetime.
The first in a five part series on the applications of activated carbon, desalination is discussed here. With certain parts of the world consistently suffering from a poor potable water supply, the concept of desalination is appealing. Contemporary methods for removing the salt from seawater are expensive and energy intensive. The use of activated carbon may help alleviate some of these concerns.
The modern foundry producer is interested in the production of the best quality product without compromise - wetting can be a cause of some problems in the metals casting process.
Coal as mined is not a worthy material for modern combustion, owing to its large quantity of sulfur compounds amongst others. When burned, these release toxic gases. Coal washing reduces the amount of these gases released on burning - by helping to remove them from the coal. The addition of zinc chloride to a coal beneficiation process can lead to the production of activated carbon products.
Iron pyrite already has myriad uses, from the production of sulfur compounds to an additive in several types of commercial glass. In the metals refining space, pyrite is prized for use in the refining of lead, where it is an essential component, and the removal of copper from that molten lead and associated slags.
Crucial to the identity of the refractory material itself is how it performs in elevated temperatures - but this isn’t the only area where a refractory needs to excel. Certain applications require elevated levels of compressive strength and specific porosity profiles.
Charcoal briquettes are the economical choice when it comes to domestic solid fuel - and are desirable from a manufacturing point of view too.
Pyrite is an up and coming material for the production of solar cells - with high efficiencies and low costs potentially making low carbon power generation cheaper and more widely attainable for consumers.
Addition of glass powders can increase production efficiency, cost and the quality of bricks and ceramic glazes.
A different kind of stored energy: far from the traditional application of anthracite as a fuel, it can be ground and incorporated into battery components such as anodes and casings.
