Hydrated cement produces CaO. So calcium oxide is a major constituent. Silicon dioxide is also produced resulting in calcium silicate.
Non-metallic
metal and metallic are the same thing arent they??
metallic oxide
A metallic oxide is basic in nature.
An oxide as its name suggests is a chemical compound that consists of some atom bonded (either covalent or ionic) to one or more oxygen atoms. The two major oxides that exist are metallic oxides or non-metallic oxides.
Aluminium oxide (Al2O3) is a solid, the oxide of a metal.
When water is mixed with a metallic oxide, a metal hydroxide is typically formed. This reaction is known as a neutralization reaction, which involves the combination of the hydroxide ion from water with the metal ion from the metallic oxide.
Aluminum oxide is not considered metallic because it is a ceramic material. It is a compound formed between aluminum and oxygen, and it exhibits properties such as high hardness, electrical insulation, and thermal resistance.
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
When water is added to a metallic oxide, it forms a metal hydroxide (also known as basic oxide) and releases heat in an exothermic reaction. For example, when water is added to calcium oxide, it forms calcium hydroxide.
Lead oxide is considered a metal oxide because it is composed of lead, a metal, combined with oxygen, a nonmetal. In its most common form, lead(II) oxide (PbO), it exhibits properties typical of metal oxides, such as being a semiconductor and having a high melting point. Thus, while it contains both metal and nonmetal components, lead oxide itself is classified based on its metallic constituent.
No: Lead by itself is a metal, but lead oxide is a compound, and compounds are never metals. Note, however, that mixtures of metals, usually called alloys, do exist and are metallic. These alloys are not compounds because they do not have fixed compositions that are the ratios of small whole numbers of atoms of each constituent.
