What Are Micro-Titanium Spheres? Miniscule beads of titanium are created using the Phild Process. These perfectly spherical beads can then be mixed into a compound to be printed or layered directly onto material to target specific areas of the body with concentrated effectiveness. At first glance, the inner core of Phiten necklaces and bracelets may look like mere rubber. However, it actually contains Micro-Titanium Spheres and Carbonized Titanium held together in a compound by the elastomer rubber.
