Structural materials encompass a wide range of compounds frommetals and alloys to ceramics. Some compounds can find veryunexpected applications.

Ceramics

Ceramics are nonmetallic, inorganic materials typically formed aspowders and often sintered into useful forms. They encompass a widerange of structures from amorphous to polycrystalline or even singlecrystals. They are typically very hard but rigid, and tend to break undermechanical stress. Since they are nonmetallic, they are usually electricallynonconductive or wide band-gap semiconductors but can be doped todecrease the band-gap to the semiconductor regime. They are oftennoted for their thermal stability at high temperatures.

Silicon carbide for example has excellent high-temperaturecharacteristics but due to its brittleness has limited utility as a structuralmaterial. Micron-thin coatings of alumina (Al2O3) on SiC platelets gives acomposite which is 2–3 times stronger than traditional SiC ceramics. Theresult is a stress- and oxidation-resistant material for high-temperaturestructural applications.1 Silicon carbide is also used to enhance theproperties of other structural materials. Titanium composites inlaid withSiC monofilaments yield a stiff, strong, thermally stable structuralmaterial used in aircraft components.2

Alumina is a common and versatile structural ceramic due to itschemical, electrical, mechanical, and thermal properties. It possessespoor fracture resistance, however. The addition of yttria stabilizedzirconia to alumina significantly improves the fracture toughness ofAl2O3.

Engineering Polymers

Enginnering polymer are materials with exceptional mechanicalproperties such as stiffness, toughness, and low creep that makes themvaluable in the manufacture of structural products like gears, bearing,electronic devices, and auto parts.4-6 Typical engineering plastics includeacetals, polyamides, poly(amide-imide)s, polyarylates, poly(etheretherketone)s, poly(ether-imides)s, poly(phenylene oxide)s,poly(phenylene sulfide)s, and polysulfones.7

Polyamides are crystalline and have good impact strength, toughness,and abrasion resistance. Polyesters are often used with fillers likefiberglass, mica, and minerals to increase strength and stiffness. Sulfone-containing polymers show high resistance to acids and alkalis. Thesethermally stable polymers are used in electronic connectors, circuitboards, sterilizable items, and appliance covers.8 Polyimides haveoutstanding thermal properties. Additionally, thermoplastics,thermosets, and rubbers have significant applications as engineeringpolymers.9

Preparation of newstabilized, oxide ion-conducting, bismuth vanadate phases by amicrowave assisted method, fromV2O5, Bi2O3 and other solidoxides, was reported.
