The word for impure metals is "alloy." An alloy is a mixture of a metal with other elements, often to improve its properties like strength or corrosion resistance. Examples of alloys include bronze (copper and tin) and steel (iron and carbon).
Impure - a material who have other contaminants.
Metals can be found impure, when they are extracted from the earth's crust, where they may be combined with other chemical elements, in which case they may need to be chemically separated to make it the best for use.
Impure aluminum typically refers to aluminum that contains various alloying elements or impurities, such as silicon, iron, copper, manganese, magnesium, or other metals. These impurities can be present due to the refining process or as a result of recycling. The presence of these elements can affect the physical and mechanical properties of the aluminum, influencing its strength, ductility, and corrosion resistance. Common examples of impure aluminum include aluminum scrap or lower-grade aluminum alloys used in specific applications.
Consuming impure water can lead to various health issues such as gastrointestinal problems, infections, and diseases. Impurities in water can contain harmful bacteria, viruses, parasites, chemicals, heavy metals, or toxins that can cause illness and weaken the immune system. It is important to ensure that the water we drink is clean and safe for consumption to prevent health complications.
Sulphur can be pure or impure depending on it's source.For that matter no substance can be classified as pure or impure just by it's name.It depends on what chemists call ASSAY.Whenever you buy a chemical ask for ASSAY,you will know it's purity.Sometimes , even if the purity is not 100%,the chemical can be used if the impurity does not affect the product.Even the so called pure metals will have some amount of impurity
Impure - a material who have other contaminants.
The soul of the sinner was impure. (I know it sounds religious, but that's all I could think of )
IMPURE
The word is contaminate.
Generally an impure material is cheaper than a pure material; the word advantage is not so adequate here - can use pure or impure, this depends on the specific applications.
"Pollute" -- your question shouldn't be in the Science category.
The prefix is un-, meaning not, for the opposites unclean, untarnished, or uncluttered.The prefix im-, also meaning not, is used for other possible antonyms, impure or imprecise.
Metals can be found impure, when they are extracted from the earth's crust, where they may be combined with other chemical elements, in which case they may need to be chemically separated to make it the best for use.
The base word for contamination is 'contaminate,' which means to make something impure or to pollute it.
The word metals has two syllables. (Me-tals)
Scum means - A filmy layer of extraneous or impure matter that forms on or rises to the surface of a liquid or body of water. Or The refuse or dross of molten metals. It is also used as a term of detriment to people ,to mean low life, "he is the Scum of the earth"
