Judgment of carbon content in molten steel at the end point
Carbon Steel Heat Treatment and Final Product Carbon Analysis
1. Introduction
Steel manufacture and heat treatment processes are considered by many to be among the oldest and most dangerous industrial practices humanity has produced. As technology increases, so does our understanding of how this......
nuclear scale
Nuclear balances are among some of the most precise weighing instruments available. They are designed to weigh with high accuracy, helping scientific laboratories in many countries perform incredibly precise measurements.
Nuclear balances get their name because they make use of a technology call......
asphalt glass transition temperature
Transformation Temperature of Asphalt Glass
Glass transition temperature is a very important parameter in asphalt pavement structure engineering. The definition of glass transition temperature is the temperature range between the rigid glass state and the soft rubbery state of a material.
Gla......
gallium arsenide
Gallium arsenide (Gaas) is a compound of the elements gallium and arsenic. It is an important semiconductor material used in most high-speed and high-frequency electronic devices. Gaas was discovered in 1915 by German chemist Alfred Stock and is the most commonly used compound semiconductor of the ......
Single Crystal Growth by Bridgmann Method
？
Bridgman–Stockbarger single crystal growth is one of the important process for the fabricating high-efficiency, high-quality optical and electronic materials. The basic principle of the process originated from the work of Percy W. Bridgman and Wilson D. Stockbarger，who independently studied an......
degenerate semiconductor
Introduction
A semiconductor is a material that has certain electrical properties between that of an insulator and a conductor. Semiconductors can be either intrinsic or extrinsic. Intrinsic semiconductors are composed of silicon and germanium while extrinsic are composed of one of those two mate......
Germanium Single Crystal for Radiation Detector
Gallium Arsenide (Gaas) Single Crystal Detectors
Gallium arsenide (Gaas) is a compound material that is composed of gallium and arsenic and is often used as a semiconductor in a variety of fields, such as electronics, optics, and radiation detection. Gaas single crystal detectors, in particular, ......
Semiconductor materials for light emission
Introduction
Light-emitting diodes (LEDs) are one of the most promising semiconductor materials used for light emission applications in the past decades. LEDs are widely used in consumer electronic products, automotive lighting, display industry, and lighting industry. LEDs are also used for illu......
Elemental Semiconductor Materials
Introduction
A semiconductor material is a material that operates as an electrical conductor at one extreme and as an electrical insulator at the other extreme. Semi-conductors can be used to build transistors, amplifiers, and logic circuits, and are among the most important materials used in ele......
