Boron carbide is a highly hard ceramic material. This ceramic material can be used to make tank armor, industrial armor, as well as body armor. It ranks fifth in the hardest material list after diamonds and cubic boron nutride, fullerene complexes and monofilaments. It was first discovered by metalboride researchers in the 19thcentury. Scientifically, this …
While silicon nitride has been discovered since the mid-19th century, due to its covalent connection it is difficult to create. Silicon nitride Ceramic is a high quality engineering ceramic. It has excellent mechanical properties, such as strength, toughness, fracture resistance, hardness, wear resistant, chemical and thermal stability, and wear resistance. Silicon nitride (also known as …
Powders with particle sizes between 1-10 nm and 100-100 nm are called nanopowder. These nanoparticles are able to exhibit many superior properties than other micron-scale particles, including a microscopic quantum tunneling, small size effects, and large specific surfaces. Copper Nanoparticles Properties: A copper nano-powder, also known as purple-brown and purple-black, is used to create microelectronic …
The preparation Aluminum oxide can broadly be divided into 3 categories: solid phase method, liquid method, and gasphase method. Gas phase method Laser induced vapor deposition The laser inducedvapor deposition technology is a method that uses lasers to infuse a temperature high enough to allow reactants to rapidly react and produce ultrafine particle embryos. These …
Graphene is an example of a two-dimensional materials and it has been widely utilized in many areas. Now, let’s clarify what two-dimensional materials are. A two-dimensional material refers to materials in that electrons move freely (planar) on nonnanoscale (1–100 nm), and in two dimensions. These materials include: graphene; boron nutride; transition metal compound (disulfide); Molybdenum; …
With the development of ULSI, ultra-large-scale circuits (ULC) are rapidly becoming more accessible. This means that the devices and their dimensions are shrinking. The demands placed on the device’s size, quality, uniformity, and thickness of the film is also growing. The lines of most semiconductor devices have a width of 0.1 m and less. It …
Silver nanopowder refers to a metallic silver element having a size range of nanometers. Its excellent electrical conductivity makes silver nanopowder a vital component in the field microelectronics. Due to its surface and quantum size effects silver nanopowder can also be used for medical purposes, as well as surface-enhanced Raman applications. It can kill more …
Boron is a well-known name in chemistry. The Nobel Prize for Chemistry has been won by two scientists who worked on boron. Glasses, washing powder, and glass are where most boron is found. It has been long believed that diamond is the hardest thing in the world. One of the coolest properties of boron-based compounds …
