About CDP Technology

Tanks of carbon dioxide are used in CDP production

Cold Detonation Physics (CDP) is an new field of detonation mechanics that is based on the rapid reduction of carbon dioxide back to carbon.  By comparison, conventional explosives operate on the principle of rapid combustion of carbon to carbon dioxide facilitated through a nitrogen-based oxygen source.

CDP has several special features that traditional explosives do not:

  1. CDP formulations are 100% nitrogen-free and therefore do not produce highly toxic NOx gases when used.
  2. Detonation produces diamond, metal oxides and many other solid materials, all possessing remarkable abrasive qualities.
  3. If a CDP shot fails it can be left for 4 – 12 hours, which causes the explosive to become insensitive and 100% safe to clean up.

CDP systems are intimate combinations of dry ice (frozen carbon dioxide), and reducing agents such as magnesium and aluminum.  Other materials, such as boron and silicon, may be added to augment the detonation and generate different explosive byproducts.  CDP formulations are nitrogen-free carbon producing explosives that detonate with tremendous force.

When CDP formulations detonate, about 50% – 70% of the explosive mass is converted into very fine powders.  These powders are comprised of about 90% – 95% oxides and the balance is carbon in various phases, including diamond. CDP produces metal oxides that are fortified by the properties of diamond.

CDP is one of the only methods that can process CO2 into an inert material that has a high market value.  CDP is sophisticated carbon-capture technology that can be used to make a material whose application in several industries can improve manufacturing efficiency and generate environmental benefits.

Harnessing CDP to produce abrasive powders requires sophisticated steps with the right expertise, equipment and ingredients.  We produce dry ice of a particular particle size, combine this with a proprietary amount of powdered reducing agents, pack the mixture into a steel containment system, and detonate this inside of a huge blast chamber.

After detonation we remove CDP abrasives from the blast chamber via vacuum extraction starting with the removal of airborne particles.  Once the vessel’s atmosphere has been adequately cleared, a worker enters to recover material that has settled on the ground.

We refer to the post-detonation byproducts as CDP Abrasives.
