Plain Al2O3 alumina

nanospheres and microspheres

 

We are only supplier of truly uniform and monodisperse alumina ( aluminum oxide) microspheres and nanospheres.

Our alumina nanospheres and microspheres have been used in various applications due to

  • the  size uniformity

  • the high degree of particle sphericity (as result, high flowability and high packing density)

  • properties of alumina, such as high thermal conductivity, heat resistance, hardness etc.

These particles often used as a fillers with high thermal conductivity, for example, those fillers for thermal conductivity sheets

 

Properties of alumina

microspheres and nanospheres:

Size: nanospheres 100-950nm, microspheres 1-100m.

Solubility in water: insoluble

Solubility in organic solvents: insoluble.

Specific Gravity: 3.75-3.69g/cm3.

Crystal structure: crystalline, α-Al2O3 Corundum phase

Surface area: less than 2-3m2/g, non-porous

Surface charge: positive (pH9.3) and negative (pH9.3).

While the polymer and silica microparticles have been commonly used due to

 

Functional surface

alumina microspheres and nanospheres:

Currently we offer alumina microspheres and nanospheres with plain, amino and carboxyl functional groups. The alumina microspheres and nanospheres are also available on custom synthesis basis with other functional groups such as albumin, protein A, epoxy, NHS, NTA, EDTA et others. Please ask for delivery time and quotation.

They are useful for coupling of DNA, oligonucleotides, oligopeptides, proteins, lectines and antibodies.

Dyed and fluorescent

alumina microspheres and nanospheres:

Currently not available

 

Doped with other elements

alumina microspheres and nanospheres:

On custom synthesis basis we can dope these microparticles selected other elements with up to 2 %. The doped elements could be distributed uniformly, internally or externally.
