The artificial radioisotope 192Ir was obtained by neutron radiation from the stable element 191Ir.
Decay gives off radioactivity, with a half-life of 74.2d, and is often used in industrial testing. (in normal circumstances, after 10 half-lives of radioactive materials, the radiation intensity is not strong enough to cause harm, and the use of iridium source for industrial detection is a relatively safe option.
Platinum group metals, also known as platinum group elements. Six metallic elements, including platinum (Pt), palladium (Pd), osmium (Os), iridium (Ir), ruthenium (Ru) and rhodium (Rh), belong to cycle 5 and 6 in the periodic table. Native element in the gemological application widely, including precious metals palladium jewelry - white to be bestowed favor on newly, the international fashion jewelry platinum, palladium for pge deposit in a minimum of two kinds of mineral and metallurgical properties of the two is quite similar, because its too rare, similar purposes, so often do substitute each other in the various applications.Continue Reading →
General welding and brazing (brazing) and soft soldering (soldering) the difference between soft brazing melting by lower melting point (below the melting point of workpiece itself) to form solder connection, without heating melting the artifact itself.
There are many sources of energy for welding, including gas flame, arc, laser, electron beam, friction and ultrasonic wave. In addition to being used in factories, welding can be done in a variety of environments, such as fields, underwater and space. No matter where it is, welding may bring danger to the operator, so proper protective measures must be taken in welding. The possible injuries caused by welding include burns, electrocution, visual impairment, inhalation of toxic gases, and excessive exposure to ultraviolet rays.

In nature, vanadium is difficult to exist in a single body, mainly forming symbiotic ore or compound ore with other minerals. Now find contain vanadium mineral there are more than 70, but the main minerals have the following 3 kinds: vanadium titanium magnetite (in the world except the United States v extraction from potassium vanadium uranium, other countries mainly produce vanadium in extracting vanadium from vanadium titanium magnetite); Potassium vanadium uranium ore (a major source of this mineral in the United States and elsewhere); Petroleum-associated ore (a mineral that lives in crude oil and is increasingly important in central American countries because of its abundance). At present, 98% of the proven reserves of vanadium resources are found in vanadium titanium magnetite, and the content of V2O5 can reach 1.8%.Continue Reading →

Rhenium can increase the creep strength of nickel-high temperature alloys, which can be used to make combustion Chambers, turbine blades and exhaust nozzles for jet engines. Rhenium nickel alloy is the core material of modern jet engine blade, turbine disc and other important structural parts. The use of rhenium can improve the performance of nickel-based high temperature alloys. Alloys can also be made for single crystal blades. Both of these functions allow turbines, especially high-pressure ones, to operate at higher temperatures. In this way, the designers can increase the pressure on the turbine and improve the operating efficiency. Or the engine could speed up fuel combustion and generate more thrust. In addition, the operating temperature can be kept low and the difference between the actual operating temperature and the maximum allowable temperature of the turbine can be increased, thus extending the service life. People can also consider both aspects of the engine and improve the performance and durability of the engine.Continue Reading →
