Secondary Hardening of Steel
Introduction
Secondary hardening of steel is a process used to harden a metal after it has been heat-treated. This process strengthens the metal and makes it more durable. The secondary hardening process uses an induction heater and a metal alloy to achieve a hardening......

Volatile smelting
Volatile melting
Volatile melting occurs when elements have different boiling points, but mix together at the same temperature. The result is a mixture of materials that can usually be propelled or heated to create movement. This phenomenon is most often seen in the extraction of metal alloys, su......
Anhydrous Glauber's Salt
Waterless Calomel
Waterless Calomel is an inorganic compound of mercury and chlorine that, when dry, is an excellent electrical insulator, having a high dielectric constant. It is commonly used in electrical contacts and as a lubricant. It is also used as a corrosion inhibitor to protect metal su......
Preparation of High Purity Elements
Preparation of high purity elements
High purity elements are substances consisting of atoms made up of a single type of atom, or of a single type of group of atoms (also called molecules). These substances are highly sought after in many fields, from science and technology, to medicine and agricu......
Germanium Extraction by Classical Chlorination
Chlorination Method for Extracting Tungsten
Tungsten is a metal commonly used for the production of alloys, magnets, and cutting tools, as well as for its radiation shielding properties. However, in order to be able to use tungsten, it first needs to be extracted from its ores. One of the most co......
Extraction of germanium from coal again by volatilization
Extraction of Germanium from Coal
Germanium is a element that is widely used in many industries. In the optical, microwave and infrared communication industries, it is widely used as an optoelectronic material. In the aerospace industry, it is widely used as a material for other aspects of the ae......
Purification by Thermal Dissociation of Zirconium Iodide
Introduction
The collection and purification of rare earth elements is an important process in the modern technology industry. Rare earth elements are often found as a mixture of oxides and other compounds and must be purified to be used for a variety of applications. In this study, a method for ......
Production of Beryllium Metal by Molten Salt Electrolysis
The Production of Metal Beryllium Using Molten Salt Electrolysis
Molten salt electrolysis is an effective and beneficial way of producing high-purity metal beryllium products due to its energy-saving features, high efficiency, and lack of environmental pollution. From the production point of view......
Pyrometallurgy
The process of smelting zinc by fire has been around for centuries, but the science of it has only recently been well understood. The process involves heating the ore to very high temperatures, usually to around 1000°C (1830°F). During this process, the ore is heated until it partially melts, fo......
Production of high-purity arsenic
Preparation of High-Purity Arsenic
Arsenic is a metalloid element in Group 15 of the Periodic Table. It is widely used in industry and found in many everyday items. The preparation of high-purity arsenic from arsenic trioxide is a relatively simple process. In this article, we will discuss the va......
