Ebonex Electrically Conductive Ceramic Powder
Ebonex electrically conductive ceramic powder is the cornerstone of Atraverda. This advanced ceramic material enables higher performing advanced batteries, new water treatment techniques, and longer-lasting, reinforced concrete structures.
Ebonex substrates allow customers to more easily develop new markets and applications based on electrically conductive ceramics.
Atraverda owns the intellectual property rights to this very unique, electrically conductive material known worldwide through its trademark, Ebonex®. Atraverda produces this powder at its manufacturing facility by converting a common material TiO2 through a proprietary process into the electrically conductive ceramic powder called Ebonex®. Atraverda also produces substrates based on Ebonex® at the same manufacturing facility.
Ebonex Science
Ebonex® ceramic is a metallic-type conductor with conductivity comparable to that of carbon, but with superior oxidation resistance. Its crystal structure of the titanium suboxides provides a combination of corrosion resistance, oxidation resistance and electrical conductivity.
The parent structure is rutile titanium dioxide, which can be described as a network of TiO6 octahedra sharing edges in a plane and edges along the axis perpendicular to that plane.
The titanium suboxides (TinO2n-1) can be defined as a sheared rutile structure, accommodating the oxygen deficiency in the structure by the formation of crystal shear planes along the nth plane of octahedral.
For example, Ti407 has one TiO layer for every 3 TiO2 layers. The TiO plane is attached to the adjacent TiO2 plane via shared faces instead of shared edges as in rutile titania. The result is a conductive band intimately surrounded by titania. The conductivity of Ebonex® ceramic material arises from the TiO layers and the chemical resistance from the TiO2 layers sandwiching and protecting the TiO layer.

Water Treatment
Atraverda’s Ebonex® technology is a platform technology with applications beyond revolutionary bi-polar batteries. Atranova has exclusive access to Ebonex® technology worldwide which can be used in a broad range of applications in the fields of water and effluent treatment.
The primary use of Ebonex® technology currently is for reduction of COD levels, thereby producing significant savings under the Mogden formulas. This is the basis under which industry is charged for discharging to sewer.
Atranova utilizes Ebonex® in rod format as the basis for its MBB Technology. As water or effluent flows up through the MBB system, direct chemical changes occur when ions make contact with the Ebonex® electrodes. The most significant effect is the formation of free radicals (such as hydroxyl and oxygen radicals) which are highly reactive. The surface charge of these radicals is altered by the electrode charge, reducing the surface negative charge and resulting in the formation of small particulate matter previously in solution.
These agglomerate into larger particles by attraction to oppositely charged particles which can then be removed by filtration. The Atranova water treatment system has been shown to be successful in the following areas of application:
- Reduction of gross contamination in industrial effluents e.g. removal of COD, solids and increasing the ability to recycle or re-use so as to reduce costs of disposal.
- Disinfection either directly by killing organisms by passing through an electric charge, or through in-situ chlorine production to kill pathogenic organisms in water sources.
- Removal of organics and micro contaminants from potable water. Atranova’s technology therefore offers a solution to the increasing legislation for distributed water purification in the developed and developing countries and can also provide a simple safe solution to the provision of drinking water in many underdeveloped areas of the world.
