About Ceramic Magnets
Ceramic Magnets Ceramic magnets, also known as ferrite magnets, are man-made magnets made up of iron oxide and strontium carbonate that undergo sintering to bond all their raw materials together before being finished with finish grinding for final finish.
Ceramic magnets require two key raw materials that consume considerable energy during their extraction, production and transportation processes as well as over their lifespans.
Ceramic Magnets Uses School Home & Office
Ceramic or "ferrite" magnets are created from iron oxide and strontium carbonate by heating them together until a chemical reaction takes place, producing a magnetic material with magnetic properties.
These magnets are then pressed and ground into their final shapes, creating waste such as filings, leftovers and nitrogen oxide that is safely disposed of after production has taken place. Manufacturing ceramic magnets requires energy intensive processes which require distribution and transportation services as well.
Ceramic magnets are an ideal choice for students engaging in educational activities or crafts projects, while also being popular at home where they can create creative storage solutions or be used in DIY projects. Ceramics are less costly than their neodymium counterparts and their durability allows for use in stressful environments like high temperatures or vibrations without demagnetizing; making them suitable magnet therapy magnets as they come coated in epoxy, zinc, neodymium and PTFE with different coating options providing unique benefits.
Ceramic Magnets in Industry
Ceramic magnets can be found in many industries, from DC motors and magnetic separators to sensors. Ceramic magnets are composed of iron oxide and strontium carbonate materials treated to industrial heating processes known as calcining that transform them into ferrite magnet powder (LeBlanc).
Once raw materials have been produced, they must be compressed to achieve their final form. Material must then be injected or compressed into die cavities which represent the final magnet shape before being sintered at high temperatures - similar to firing pottery in a kiln. This process turns individual particles of raw materials into solid magnets with high coercivity values (LeBlanc).
Producing ceramic magnets requires considerable amounts of energy. From mining, production and shipping; usually from China in ships running on bunker fuel which is refined crude oil ("Ceramic Magnet Handling & Storage"). When magnets arrive at their destinations they still require energy for demagnitization processes.
Ceramic Magnets Shapes
Ceramic ferrite magnets offered for sale come in a range of shapes and sizes including blocks, discs, rings and other items. Our ceramic ferrite magnets offer good corrosion resistance as well as being suitable for moderate heat environments; additionally, their high intrinsic coercivity means they resist external demagnetization (though low temperatures may result in irreversible loss).
Manufacturing requires heavy machinery that consumes energy in the form of fossil-fuel electricity and exhaust gas emissions from sintering and grinding processes, creating magnetic particles with anisotropic pull characteristics - meaning only strong pull in one direction.
Ceramics can be enhanced through various plating and coating options to increase performance, durability, and aesthetics. Their hard and brittle nature make them unsuitable for structural applications; instead they should be used decoratively. Ceramic ferrite magnets are sensitive to impact and should be handled carefully when dropped; traditional packaging materials used produce airborne wastes which pollute our environment; however some companies now use bio material that is recyclable ("Green VCI"). On average a typical ceramic/ferrite magnet lasts 10 years in its lifespan.
Ceramic Magnets The Best Craft Magnets
Ceramic magnets make excellent crafting magnets due to their versatility, reliability, and durability. They can withstand heat and cold extremes while remaining resistant to demagnetization and corrosion - perfect for creating magnetic clasps, bookmarks and more!
Craft magnets are easy to use and come in various shapes. Once attached to any surface, these craft magnets can be cut using scissors or knives for cutting ease - making them very cost-effective as compared to other forms of magnets.
There are 27 grades of Ferrite Magnet (Ceramic magnets), from pencil lead-shaped ones to more specialised designs used for operating an MRI scanner or starting a lawnmower. Ceramic magnets are commonly found in motors, generators and loudspeakers due to being corrosion resistant yet relatively affordable; additionally they're great for magnetic separation equipment as well as automotive sensors; finally they make for excellent high temperature magnets!
Where to Purchase Ceramic Magnets
Ceramic (also known as ferrite) magnets are an affordable, versatile craft magnet option that's great for craft projects and hobbies alike. Their dark grey hue and pencil lead-like feel makes them great choices, while their ferrimagnetic performance provides strong magnetic pull for their size without reaching Neodymium or Samarium levels.
Magnets are created using powder technology using two raw materials, iron oxide and strontium carbonate. The granular substance obtained can then either be dry pressed or wet injected into a die fitted with carbide liners to form its shape.
Producing ceramic magnets requires energy in the form of fossil fuels for mining and transportation, as well as energy needed to affix them to surfaces using adhesives - this requires additional energy as well as materials like corrosion-inhibiting paper, plastic spacers and foam spacers.
Once magnets reach the end of their lifespan, they can either be melted down and recycled into new products or recycled into a rare-earth raw material called samarium cobalt, which is used in making most neodymium and samarium magnets produced today ("Recovery of Samarium Cobalt Waste Powders through Magnet Recycling").
