Boron Carbide powder overview Boron carbide The characteristics include low density, strength, excellent high temperature stability and chemical stability. This makes it a popular choice for wear-resistant material, ceramic reinforcement phases, lightweight armor and reactor neutron absorbers. It is also easier to produce than diamond or cubic boron nutride, making it more popular. You can …
What’s Scandium Oxide powder? Scandiumoxide has been a key product in the scandium industry. The physical and chemical characteristics of this product is very similar to that of rare earths oxides. Therefore, production techniques are quite similar. Sc2O3 may produce metal scandium and other scandium alloys under certain environmental conditions. Scandium oxide has many uses …
What is hafnium caride? Hafnium carbide, also known as HfC (hafnium-carbonide), is a chemical mixture of carbon and hafnium. It is one of most reactive binary compounds and has a melting temperature around 3900degC. Although it is extremely resistant to oxidation, oxidation can occur at temperatures up to 430 degrees Celsius. The heat shield of …
Noble metal This is scandium’s most central member of the family of rare Earth elements. The actual worldwide production of scandium in 2016 was less than one ton. That means every person who is more than seven thousand can obtain 1 gram. The availability of scandium, which is rarer than rare earth, rare-earth, or gold, …
What are surfactants, and how do they work? Surfactants belong to a class that reduces surface tension. They can be adsorb on interfaces such as gas-liquids or liquids-liquids. By doing so, they change the properties and affect the stability, wettability of the interfaces. Surfactants can be found in many fields including industry, agriculture and medicine. …
boron trisulfide is a yellow to white crystal or amorphous powder that turns paste upon heating. It is soluble in sulfur dichloride, phosphorus trichloride, and alcohols but not in water or at room temperature. It reacts with iron boroide to form boric acid.Corrosive to eyes, skin and respiratory tract. May cause lung edema when inhaled. …
