Functional Ferrite Powders
Please click on the ferrite powder types below for more information about their unique qualities and applications.
Large-Particle Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
This large-particle formulation is a soft ferrite powder with an average particle size of 200µm~5mm. The large particles are safe and easy to handle and can be used in a wide array of applications.
Applications of large-particle ferrite powders:
Powder transport, magnetic fillers, electrophotographic carrier powders, and many more
High Specific Surface Area, Small-Particle Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
This spherical soft ferrite powder has an average particle size of 5~30µm. The particle surface can be customized from smooth to wrinkled. The large surface area and the customizable surface design ensure flexible yet highly functional performance.
Applications of high specific surface area,
small-particle ferrite powders:
Water treatment, soil remediation, absorbents, filters, and many more
FDA-Approved Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
Powdertech’s U.S. Food and Drug Administration-approved ferrite powder formulations are available in both soft and hard types. These powders are suitable for medical and cosmetic applications.
Upon request, our FDA-approved powders can be customized with FDA-approved resin coatings.
Applications of FDA-approved ferrite powders:
Blood test kits, analyses for biological studies, and many more
Spherical Nano Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
This spherical ultrafine nanoscale soft ferrite powder is produced by a special sintering method. Because these ferrite particles are metal oxides, this ultrafine ferrite powder is oxidation-resistant and lasts longer than nanoparticles of regular metal powders, providing chemical stability.
These ultrafine ferrite particles have high dispersion capability in various solvents, and are suitable for magnetic ink, magnetic fluid, etc. In addition to the powders themselves, we also offer a variety of liquid solutions with dispersed ultrafine ferrite powders.
Applications of spherical nano ferrite powders:
Magnetic fillers, magnetic fluid, magnetic ink, and many more
Flake-Shaped Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
Our flake-shaped ferrite powder has good orientation, making it suitable as filler for electromagnetic wave shielding. The ferrite composition design and particle characteristics such as thickness and particle size can be customized upon request.
This flake-shaped powder, a metallic oxide, is also suitable for pigments, its metallic luster deriving from the flat and very smooth particle surface.
Applications of flake-shaped ferrite powders:
Electromagnetic wave shielding, pigments, and many more
Shell-Structured Ferrite Powder*
*Ferrite powders belong to a class of products known as “functional materials”—that is, materials designed to perform specific tasks. Powdertech offers multiple ferrite powder formulations differing in particle size, surface texture, and other characteristics. Each formulation is designed to respond to specific customer needs.
In producing spherical ferrite powders, it is almost impossible to control the outside and inside structures separately.
However, we have successfully developed spherical ferrite particles with porous parts inside and a shell-structured surface outside. This new line of particles combines high pore volume and low apparent density, making it a good choice for low-weight functional magnetic fillers. In addition, with the high pore volume structure inside, this powder can be used for catalyst support or absorbents.
Applications of shell-structured ferrite powders:
Catalyst support, low-density fillers, absorbents, filters, and many more
