Properties
Describes a force applied to an object that attempts to stretch the object.
Tension
What type of bonding shares electrons
Covalent
A reddish brown metal, which is malleable, ductile with high electrical and heat conductivity and is highly corrosion-resistant and takes a high polish
Copper
Once set cannot be reshaped
Thermoset
The most common glass former as it is easily cooled without crystallising and forms the basis of all commercial glasses.
Silica
Resist indentation or scratching when brought into contact with another material.
Hardness
Bonds formed between ions with opposite charges
Ionic
A very light metal with low specific gravity but has very good conductive capacity. It is an extremely good conductor of electricity. Has excellent corrosion resistance as well, as it readily forms an inert oxide when exposed to the atmosphere.
Aluminium
Can be reformed
Thermosoftening
This surface‑coating step applies a glassy layer that improves chemical resistance, hygiene, and appearance after firing.
Glazing
Material maintains its shape
Stiffness
The parent name for Hydrogen Bonding
Van-Der-Waals Forces
State the advantage, when in service, that a non-ferrous pop rivet has compared to a ferrous rivet.
A non‑ferrous pop rivet offers superior corrosion resistance in service, meaning it is less likely to rust, seize, or degrade, which helps maintain joint integrity and reduces maintenance over the product’s life.
Increasing polymer strength by forming covalent links between chains reduces flexibility but improves thermal stability. It makes a more rigid polymer.
Cross-Linking
This microstructural feature reduces strength and acts as a stress concentrator, making ceramic components more susceptible to crack initiation.
Porosity
Withstand the application of impact force without failure.
Toughness
Formed when a (very specific) atom in a polar covalent bond (O-H) is attracted to a nearby electronegative atom, this intermolecular force influences the behaviour of many engineered materials
Hydrogen Bond
This type of corrosion occurs when two dissimilar metals are electrically connected in an electrolyte, causing one to preferentially deteriorate.
Galvanic Corrosion
Substances that are incorporated during manufacture to modify characteristics such as UV resistance, flexibility, colour, and flame behaviour.
Additives
Uses a liquid suspension poured into a porous mould, allowing water to diffuse out and leaving a shaped ceramic body.
Slip Casting
Stops the passage of light. You cannot see through it.
Opacity
A type of chemical bonding that arises from the electrostatic attractive force in the form of an electron cloud of delocalized electrons and positively charged ions.
Metallic Bonding
This phenomenon occurs when plastic deformation increases dislocation density, making further deformation more difficult and raising the metal’s yield strength.
Work Hardening
This continuous manufacturing method forces heated polymer through a die to produce items like pipes, profiles, and filament feedstock.
Extrusion
This thermal process permanently hardens ceramics by driving out moisture and fusing particles at high temperatures.
Sintering
