The document delves into various material properties categorized under ecological, chemical, technological, and physical aspects. Ecological properties include recyclability, emphasizing the conversion of waste into new materials, and biodegradability, which involves the breakdown of organic matter by microorganisms.

Material Properties

Technologycal

Resilience
Toughness
is the ability of a material to absorb energy and plastically deform without fracturing.
Handness(Duresa)
Is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion.
Malleability/Ductivity
Malleability is a substance's ability to deform under pressure, and is a measure of a material's ability to undergo significant plastic deformation before rupture.
Elasticity/Plasicity
Elasticity is a measure of a variable's sensitivity to a change in another variable, and plasticity in physics and engineering, the propensity of a solid material to undergo permanent deformation under load

Topic principal

Ecologycal

Biodegrability
Is the breakdown of organic matter by microorganisms.
Toxicity
Is the degree to which a chemical substance or a particular mixture of substances can damage an organism.
Recycable
Is the process of converting waste materials into new materials and objects.

Chemical

Oxidation
a chemical reaction in which electrons are lost.
Corrosion
is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide.

Physical

Mechanical
Strength

Shear

Flexion

Compresion

the result of the subjection of a material to compressive stress.

Tension

a force related to the stretching of an object (the opposite of compression)

Torsion

is the twisting of an object due to an applied torque.

Thermal properties
Fusibility

is the ease at which the material can be fused together or to the temperature or amount of heat required to melt a material.

Expansion

an increase in the market value of an economy over time

Conductivity

a measure of its ability to conduct electricity.

Electrical properties
Semiconductors

A semiconductor material has an electrical conductivity value falling between that of a metal, like copper, gold, etc. and an insulator, such as glass.

Insulators

a substance that resists electricity.

Conductors

is an object or type of material that allows the flow of an electrical current in one or more directions.

Density
is its mass per unit volume.
Optical
Transparent

is the physical property of allowing light to pass through the material without being scattered.

Translucent

it allows light to pass through.

Opaque

the degree to which light is not allowed to travel through.
