ALLOYS

This link provides an article purposely designed for the interest of the children. For some kids, Chemistry is somehow one of the most difficult branch of science, it is great that there are such links in the internet that create an artistic way to attract interests for these kids. Here is a simple overview of the basic facts about alloys.

Alloys in this article are practically defined as the mixture or combination of two or more metals. Any metals can be a helpful way in the process of producing an alloy. Metals on the other hand are emphasized having a large part as a group of chemical elements under the periodic table. Examples of metals from the periodic table of elements were given, such as potassium (K) and calcium (Ca), as well as the gold (Au) and silver (Ag). Having alloys does not mean like mixing two or more metals alone, to be corrected, it also acceptable if metals will be combined with a non-metallic element, like for instance, carbon (C). The term used to identify people working with metals is Metallurgists. They are also the ones responsible for producing alloys and other important substances concerning metals. Metallurgists use metallurgical microscopes to examine, visualize and study details in a certain metal or an alloy as well. For these metal professionals, the metallurgical microscope is one of the best and most useful equipment to be used to characterize genuine metals and the metals used in the combination mixed in an alloy.

The amalgams are typically one of the examples of a special alloy. It is commonly used by dentists in making dental fillings. An amalgam is actually an alloy of any metals with the mixture of mercury (Hg). Mercury, as also briefly described in this article is a metal; the only characteristic that differentiates the element mercury from any other metals is that, mercury is actually in liquid form at a room temperature; unlike for some others which are mostly in solid form. The dental filling applied by dentists to the teeth is an example of an alloy as mentioned; it is a combination of mercury and silver as being sampled also from this article. As described, when the amalgam of these featured elements were first combined, expect to see a very alloy; when certain time comes, the mercury will then leave the amalgam and then the silver will remain. That is the time when the silver will become very, hard and easy to be visualized under metallurgical microscope. This is the procedure used by the dentists to actually make dental fillings for their patients, as discussed. For modernized and high technology dental concerns, dentists will no longer recommend dental filling procedure, as it has been discovered that mercury is harmful to one’s health, and that it can slowly poison the patient resulting them to get sick and feel ill. Though mercury may be a helpful element as first described regarding dental concerns, it is not always advisable to play with mercury and most especially n ever to touch it for it can really seep in through the skin.
