Barium ferrite ferrite has better packing properties. BaFe can be reduced to a smaller size and higher packing density because of its circular structure and can be stacked better. Barium ferrite Barium ferrite, abbreviated BaFe, BaM, is the chemical compound with the formula BaFeO. This and related ferrite materials are components in magnetic stripe cards and loudspeaker magnets. BaFe is described as Ba(Fe)(O). The Fe centers are ferromagnetically coupled. This area of technology is usually considered to be an application of the related fields of materials science and solid state chemistry. Barium ferrite is a highly magnetic material, has a high packing
Argentium sterling silver was discovered to impart the following properties to sterling silver: Many of these properties significantly affect the traditional methods of working silver. For instance the absence of firescale eliminates tedious and time-consuming steps required by the silver worker using traditional sterling silver. It also eliminates the need for plating the final product which is often done on manufactured items because of the problems introduced by firescale. Tarnish resistance is of significant importance to both silver workers and the wearer of silver jewellery. Argentium Silver is patented and trademarked by Argentium Silver Company, UK. Traditional sterling silver has a solidus melting
