What's the difference between titanium and warwickite?
Titanium
Definition:
(n.) An elementary substance found combined in the minerals manaccanite, rutile, sphene, etc., and isolated as an infusible iron-gray amorphous powder, having a metallic luster. It burns when heated in the air. Symbol Ti. Atomic weight 48.1.
Example Sentences:

(2) Previous work has shown that corticocancellous bone chips placed in a titanium chamber with an arteriovenous vascular pedicle will result in a pre-formed vascularized bone graft.
(3) Since the introduction of osseointegrated titanium implants for bone-anchored facial and dental prostheses, an increasing number of irradiated patients are being treated with this technique.
(4) A knee simulator was used to study the wear of carbon fiber reinforced UHMWPE (Poly Two) (Poly Two is a registered trademark of Zimmer, USA) tibial and patellar components against Ti-6A1-4V, titanium nitride (TiN)-coated Ti-6A1-4V, and cobalt-chromium-molybdenum femoral components.
(5) Using the osseointegration method, a prospective study was conducted involving seven adult patients who were treated with titanium implants used as rigid anchorage units.

(13) Results demonstrated excellent bone adaptation to both titanium and ceramic implants.
(14) A new process of plasma-spraying hydroxyapatite--an entirely biocompatible, bioceramic material--onto porous, titanium alloy components promotes bone ingrowth into the components resulting in implant fixation, which is superior to current methods of cemented or cementless fixation.
(15) The titanium alloy strips were treated with citric acid, stannous fluoride, tetracycline HCl, chlorhexidine gluconate, hydrogen peroxide, chloramine T, sterile water, a plastic sonic scaler tip, and an air-powder abrasive unit.
(16) In vitro tests demonstrated approximately sevenfold greater filter length shortening (a measure of filter splaying) for the titanium GF in response to a given applied load.

Warwickite
Definition:
(n.) A dark brown or black mineral, occurring in prismatic crystals imbedded in limestone near Warwick, New York. It consists of the borate and titanate of magnesia and iron.
