  • A word about Ferrite - Barium Core & Magnets

    I've been investigating about Ferrite Barium for Core or Magnets as we well know is good for try to replicate a Sweet VTA device, the Magnetic Resonance Amplifier or anothers device that use magnetic poles resonance. Appearently the composes ferrite with barium are more appropiate to get conditioning necessary.

    My investigation on the web and Phd's doctors and universities near to me, they explains me some about this interesting topic, the first is no very hard make our magnets or core above all for replicate a wonderfull device like the VTA. it's not very hard because materials is easy to get. haha I was sure Barium is used pure, pure is hard to find hahahh. Ok, a friend Licenced on quimic when I asked for how to get barium to oxide ferric to make my own cores or magnets. The barium is used like Barium Carbonate very easy to get including in Quimic Shops for students, the Oxide Ferrous too is piece of cake.

    The I've found a good page explains the process, is necessary burn the mixture Oxide Ferrous (80%) + Carbonate Barium (20%) @ 950 C. I think is possible make it with mineral carbon in the BBQ hahah, ok, then is necessary puverized the components and apply pressure @ 650 kg/cm2, max. maybe is complicated.

    In the market get Barium Magnets seems easy but. how we can 100% sure of this magnets if do not know are 20% Barium Carbonate?. it's the problem in the process burning both components become Blacks, and is very hard identify the normal ceramic magnet.

    Then in my investigation I've conclude for FE purpose the ideal magnets is the anisotropic magnet, this magnets is possible change the orientation for our purpose, is 100% necessary to replicate the VTA, Now my question, in my investigation, ONLY THE FERRITE BARIUM MAGNET CAN BE ANISOTROPIC. Anisotropic magnets can make possible easy to build and cheap a magnet motor, then when the magnet loose the fields, can we remagnetize them again. This magnets motors needs a little or not needs magnetic shields to make the assymetric magnetic field.

    The part more important here this composed, is usefull to experiment with antigravity and supercoducting. Barium is gold hahah.

    Here I leave the web page is in spanish but yours can use google translator, or I will help to translate if google don't make correctly

    I hope this info be usefull to everyone.

    Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

    A good supplier of ferrite products (big industrial ones) will offer a detailed product sheet, where the exact composition of the core or magnet can be found out.
    I normally write emails to manufacturers asking for more detailed info on the composition. It should be possible to obtain 20% Barium ones, i remember having stumbled about those.
    But to be 110% sure it is good to make them yourself, if you have a forge in your basement hehe.
    Reading the product sheets for different ferrite cores, it became apparent that
    there is a lot of ferrite varieties . The frequency dependent attributes of the core can vary a lot.
