  2. Ceramic - Wikipedia

    en.wikipedia.org/wiki/Ceramic

    Ceramics generally can withstand very high temperatures, ranging from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F). A low magnification SEM micrograph of an advanced ceramic material. The properties of ceramics make fracturing an important inspection method. The crystallinity of ceramic materials varies widely.

  3. Glass-ceramic - Wikipedia

    en.wikipedia.org/wiki/Glass-ceramic

    Glass-ceramic materials share many properties with both glasses and ceramics. Glass-ceramics have an amorphous phase and one or more crystalline phases and are produced by a so-called "controlled crystallization" in contrast to a spontaneous crystallization, which is usually not wanted in glass manufacturing. Glass-ceramics have the fabrication ...

    en.wikipedia.org/wiki/Ceramic_engineering

    Glass-ceramic materials share many properties with both glasses and ceramics. Glass-ceramics have an amorphous phase and one or more crystalline phases and are produced by a so-called "controlled crystallization", which is typically avoided in glass manufacturing.

  5. Nanocrystalline material - Wikipedia

    en.wikipedia.org/wiki/Nanocrystalline_material

    Additionally, nanocrystalline ceramics have been shown to sinter more rapidly than bulk ceramics, leading to higher densities and improved mechanical properties, [5] although extended exposure to the high pressures and elevated temperatures required to sinter the part to full density can result in coarsening of the nanostructure.

  6. List of piezoelectric materials - Wikipedia

    en.wikipedia.org/wiki/List_of_piezoelectric...

    This page lists properties of several commonly used piezoelectric materials. Piezoelectric materials (PMs) can be broadly classified as either crystalline, ceramic, or polymeric. [1] The most commonly produced piezoelectric ceramics are lead zirconate titanate (PZT), barium titanate, and lead titanate.

  7. Crystal structure - Wikipedia

    en.wikipedia.org/wiki/Crystal_structure

    The symmetry properties of crystal are described by the concept of space groups. [1] All possible symmetric arrangements of particles in three-dimensional space may be described by 230 space groups. The crystal structure and symmetry play a critical role in determining many physical properties, such as cleavage , electronic band structure , and ...

  8. Ultra-high temperature ceramic - Wikipedia

    en.wikipedia.org/wiki/Ultra-high_temperature_ceramic

    Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.

  9. Quartz - Wikipedia

    en.wikipedia.org/wiki/Quartz

    Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.
