👉 The Cameroon fluid, also known as the Cameroonite or Cameroonite variety of the mineral rutile, is a rare form of titanium dioxide (TiO2) that crystallizes in the monoclinic crystal system. It is named after Cameroon, where it was first discovered. This mineral exhibits a unique hexagonal prism structure with a characteristic blue to white color, often with a metallic luster. The Cameroon fluid is notable for its high purity and perfect cleavage, making it valuable in various industrial applications, particularly in the production of pigments, ceramics, and as a refractory material due to its exceptional thermal stability. Its discovery has also contributed significantly to the understanding of titanium dioxide's crystallographic properties and its diverse applications in materials science.
