Definitions
Silicon (noun)
A nonmetallic element occurring extensively in the earth’s crust in silica and silicates, having both an
amorphous and a crystalline allotrope, and used doped or in combination with other materials in glass,
semiconducting devices, concrete, brick, refractories, pottery, and silicones. Atomic number 14;
atomic weight 28.086; melting point 1,410 oC; boiling point 2,355 oC; specific gravity 2.33; valance 4.
Silicone (noun)
Any of a group of semi-inorganic polymers based on the structural unit R2SiO, where R is an organic
group, characterized by wide-range thermal stability, high lubricity, extreme water repellence, and
physio-chemical inertness, used in adhesives, lubricants, protective coatings, paints, electrical
insulation, synthetic rubber, and prosthetic replacements for bodily parts.
Silica (noun)
The dioxide of silicon, SiO2, a hard glassy mineral found in a variety of forms, as quartz, sand, flint,
agate, and many other minerals and used to manufacture a wide variety of materials, notably glass and
concrete.
Silicate (noun)
Any of numerous compounds containing silicon, oxygen, and a metallic or organic radical, occurring in
most rock, and forming the basis of common glass and bricks.
Siliceous (adjective)
Containing, resembling, pertaining to, or consisting of silica.
Silicic (adjective)
Pertaining to, resembling, or derived from silica or silicon.
Silicicolous (adjective)
Thriving in soil containing a high silica content.
Silicide (noun)
A compound of silicon with another element or radical.
Siliciferous (adjective)
Bearing, producing, or in partial combination with silica.
Silicify (verb)
To convert or become converted into silica.
Silicon dioxide (noun)
SiO2
Silicon Carbide (noun)
A bluish-black crystalline compound, SiC, one of the hardest known substances, used as an abrasive
and heat-refractory material land in single crystals as semiconductors, especially in high-temperature
applications.
Epoxy (adjective)
Containing oxygen attached to two different atoms already united in some other way.
Epoxy (noun)
Containing a 3-membered ring consisting of one oxygen and two carbon atoms.
Epoxy (noun)
Any of various usually thermosetting resins capable of forming tight cross-linked polymer
structures characterized by toughness, strong adhesion and high corrosion and chemical
resistance, used especially in surface coatings and adhesives.
Epoxy Resin (noun)
A flexible usuallly thermosetting resin made by polymerization of an epoxide and used chiefly in
coatings and adhesives.
Resin (noun)
Any of various solid or semisolid amorphous fusible viscous flammable natural organic
substances that are usually transparent or translucent and yellowish to brown, are formed
especially in plant secretions such as copal, rosin, and amber, are soluble in ether and other
organic solvents but not in water, are electrical nonconductors, and are used chiefly in varnishes,
printing inks, adhesives, synthetic plastics, and in pharmaceuticals.
Resin (noun)
Any of numerous physically similar polymerized synthetics or chemically modified natural resins
including thermoplastic materials, such as polyvinyl, polystyrene, and polyethylene, and
thermosetting materials, such as polyesters, epoxies, and silicones, that are used with fillers,
stabilizers, pigments, and other components to form plastics.
Resin (noun)
Any of a large class of synthetic products that have some of the physical properties of natural
resins but are different chemically and are used chiefly as plastics
Resin (noun)
Any of various products made from a natural resin or a natural polymer.
