A eutectic system or eutectic mixture (/ j uː ˈ t ɛ k t ɪ k / yoo-TEK-tik) [1] is a type of a homogeneous mixture that has a melting point lower than those of the constituents. [2] The lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature .
Such a mixture can be either a solid solution, eutectic or peritectic, among others. These two types of mixtures result in very different graphs. Another type of binary phase diagram is a boiling-point diagram for a mixture of two components, i. e. chemical compounds.
Eutectic bonding, also referred to as eutectic soldering, describes a wafer bonding technique with an intermediate metal layer that can produce a eutectic system. Those eutectic metals are alloys that transform directly from solid to liquid state, or vice versa from liquid to solid state, at a specific composition and temperature without ...
At the phase transition point for a substance, for instance the boiling point, the two phases involved - liquid and vapor, have identical free energies and therefore are equally likely to exist. Below the boiling point, the liquid is the more stable state of the two, whereas above the boiling point the gaseous form is the more stable.
Iron-carbon eutectic phase diagram, showing various forms of Fe x C y substances. Iron allotropes, showing the differences in structure. The alpha iron (α-Fe) is a body-centered cubic (BCC) and the gamma iron (γ-Fe) is a face-centered cubic (FCC).
Deep eutectic solvents or DESs are solutions of Lewis or Brønsted acids and bases which form a eutectic mixture. [1] Deep eutectic solvents are highly tunable through varying the structure or relative ratio of parent components and thus have a wide variety of potential applications including catalytic, separation, and electrochemical processes.
The 15-second video was encoded in a near-infrared laser and beamed from the Psyche spacecraft to the Hale Telescope at the California Institute of Technology’s Palomar Observatory.
Free viewpoint television (FTV) is a system for viewing natural video, allowing the user to interactively control the viewpoint and generate new views of a dynamic scene from any 3D position. [1] The equivalent system for computer-simulated video is known as virtual reality. With FTV, the focus of attention can be controlled by the viewers ...
