What is selenium powder and what is it used for

Selenium powder Selenium is a chemical element that has both the symbol Se as well as an atomic number of 34. This nonmetal is more commonly called a metallic (or a metalloid), with properties that lie between the elements below and above the periodic table. It also shares similarities to arsenic. It does not occur in its pure form in the Earth's crust. Selenium powder Concentrated sulfuric acid and chlorine are soluble. It can also be slightly soluble or insoluble with carbon disulfide. Sel

Talk about the past and present life of carbon nanotubes and graphene

Are carbon nanotubes graphene? Both graphene, as well carbon nanotubes, are made up of carbon atoms. Graphene can be described as a single-layer graphite layer, which is the basic unit that makes up graphite. Carbon Nanotubes are created by curling graphene. Carbon nanotubes consist mainly of carbon molecules arranged in hexagons. They form coaxial circular tubes that are made up of tens or more layers. Carbon nanotubes can also be described as graphene sheets. This is a hexagonal carbon latti

Aluminum Nitride – Property and Application |

Aluminum nitride Aluminum nitride is a powder that is either white or offwhite. What property does aluminum nitride have? AlN has a high strength at room temperatures, which increases with temperature. Aluminum nitride, with its low thermal expansion and good thermal conductivity, is an excellent material for thermal shock. It is ideal for casting pure aluminum, iron or aluminum alloys because it has a high resistance to corrosion. Aluminum nitride also has excellent dielectric propert
