NFA Instructor Tim Schade guides you through the use and application of Magnetic powder to process and collect latent print evidence at a crime scene.
When order volume exceeds a few dozen, process economics dictate a near-net shape manufacturing process with little after-work necessary. Many engineers and buyers gravitate to die casting, but there are good reasons for considering powder metal -- especially as new uses, materials, and design possibilities are unlocked thanks to evolving technology and understanding of powder metallurgy (PM).
Magnetite is one of the end members of the ulvospinel-magnetite solid solution series (Fig. 3.3) and is the most common magnetic mineral on Earth.Magnetite is a cubic mineral with inverse spinel structure. The disordering (Curie) temperature varies more or less linearly with Ti content from -150°C for ulvospinel to 580°C for magnetite (Fig. 3.4 a).

An SiO 2 coated iron oxide powder used for the preparation of an acicular metallic iron powder or an acicular magnetic iron oxide powder, is produced by forming a slurry of hydrated iron oxide as a starting material or a iron oxide powder having pH of 8 to 14; admixing a water soluble silicate at a ratio of 0.1 to 10 mol % as SiO 2 based on Fe; hydrothermally reacting said mixed slurry at 100 ...
Magnetite typically shows a nonporous structure that supports the formation of dense iron layers around the particle during the reduction. In the case of an industrial direct reduction shaft, magnetite pellets are oxidized to Fe 2 O 3 during the pelletizing process. Oxidized magnetite shows nearly the same reducibility as natural hematite.
Soft magnetic materials are great for powder metallurgy and are typically classified as either DC or AC applications: DC (Direct Current) These applications use consistently applied magnetic fields. The most common DC projects are automobile-related. These applications typically use a press and sinter process.
