Tungsten is thought to be formed from the explosions of massive stars

Instead, tungsten is thought to be formed from the explosions of massive stars. Each supernova explosion has so much energy that these newly created elements are jettisoned at incredible speeds of 30,000 km/s, or 10% of the speed of light – and that's how they get dispersed throughout the universe. Because of that, tungsten cannot be cast, forged, or rolled like other metals but must be pressed into shape while in powder form and then sintered. It is frequently alloyed with other metals, such as


How is tungsten formed

What is aluminum powder?Casting Tungsten Carbide Powder is manufactured by melting Tungsten metal and Carbon together. It has two eutectic compositions: WC and W2C. The melt is cast through quenching into extremely hard solid particles of fine crystal structure. The tungsten casting technique is now sufficiently advanced to prepare hollow and solid billets. Generally, grain size is much smaller than that normally obtained in arc-melted ingots. Improved mold surfaces virtually eliminate mold cont

The Role of Iron for Aggregation

Iron oxides are common in natural waters, not the least in dystrophic waters, where large amounts of iron and humic substances are imported from the watershed. Iron interacts with various aqueous dissolved compounds; humic substances may coprecipitate with iron-oxide particles. Iron can catalyze the photodegradation of humic substances and colored dissolved organic matter (CDOM). In addition, light and iron interactively promote particle formation from dissolved humic substances. This is suggest

Air pores in foam concrete

Moreover, the content, shape, structure, and distribution of air pores in foam concrete mainly relied on the properties of prefabricated foams, cement pastes, and the interaction between foams and cement pastes. Previously, most of the research focused on improving the cement matrix in foam concrete to increase the stability of fresh foam concrete and optimize the air pore structures. Some scholars have also studied the influence of foaming agents on the properties of foamed concrete. D.K. Panes
