Sometimes even monocrystalline materials such as diamond and sapphire are erroneously included under the term ceramics.
Property differences between metals ceramics and polymers.
Are ferrous and nonferrous metals.
The key difference between polymers and metals is that the polymers are lightweight materials compared to metals.
In general they are relatively.
Metals are of varying types and the applications of metals in the structural and mechanical work are significantly extensive however on primary basis metals can be classified in to main groups i e.
Ceramics are hard and strong but brittle.
Therefore this property of the polymer is highly advantageous because we can replace metal with plastic material if it has desirable properties that are nearly similar to the metal.
Polymers are brittle at low temperatures and have somewhat low impact strengths.
Polymer is a lower maintenance material than ceramic.
Polymers are strong and tough and often flexible.
The classification of metallic materials is explained below.
Polymer clay unlike ceramic clay will not dry out if left in the open air.
Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties.
Common objects that are made of ceramic materials.
It is also resistant to corrosion and permeable for microwaves.
Is that polymer is organic chemistry a long or larger molecule consisting of a chain or network of many repeating units formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization the joining of many monomer molecules while ceramic is uncountable a hard brittle material that is produced through burning of nonmetallic minerals at high temperatures.
Different materials have different properties.
Scissors a china tea cup a building brick a floor tile and a glass vase.
In addition many of the polymers are extremely ductile and pliable i e plastic which means they are easily formed into complex shapes.
Polymers may be ductile or brittle depending on temperature strain rate specimen geometry and way of loading which is very similar to the properties of metals.
Ceramic clay requires special attention to its use and storage.
If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size we can observe that the metal ball is heavier than the plastic ball.
If polymer clay is stored properly away from sunlight and heat it can be usable for years.
In both ceramics and polymers creep depends on time and temperature.
The properties of ceramics however also depend on their microstructure.
Composite materials combine two or more materials.
Basis are comparable to the metals and ceramics.
