Minerals (Category A)
Titanium is a strong lightweight metal often used in airplanes. When titanium combines with oxygen, it forms titanium dioxide (TiO2), a brilliant white pigment used in paint, paper, and plastics. Major deposits of titanium minerals are found in Australia, Canada, India, Norway, South Africa, Ukraine, and the United States. The sample in the photo is a mineral collector’s specimen of titanite (or sphene). However, it is not typical of the black sands often used to produce titanium metal or TiO2 pigment.
