Zirconia Light

Zirconia light is a light, similar to the calcium light, produced by incandescent zirconia. It is an intensely brilliant chemical light produced by incandescent zirconia. Zirconia is a white crystalline compound ZrO2 used especially in refractories, in thermal and electric insulation, in abrasives, and in enamels and glazes.

Zirconia light is similar in design to the Drummond light (limelight) but uses a block of zirconia instead of quicklime. Both have been replaced by electric light. Full-contour zirconia restorations are gaining in popularity. Highly translucent zirconia materials and multi-colored zirconia blocks might help to overcome the aesthetic drawbacks of traditional zirconia. To meet structural demands, zirconia is doped with stabilizers to achieve high strength and fracture toughness.

“Zirconia Light is an intensely brilliant light, similar to the Drummond light, but differing from it chiefly in the employment of cones of zirconium instead of cylinders of lime; it has been superseded by the electric light.”

It was more commonly used in the days before electric lamps. It is similar in design to the Limelight. On account of its infusibility, and brilliant luminosity when incandescent, it is used as an ingredient of sticks for the Drummond light. It is similar to the Drummond light, but differing from it chiefly in the employment of cones of zirconium instead of cylinders of lime; it has been superseded by the electric light. Zirconia-based ceramics are routinely used in structural applications in engineering, such as in the manufacture of cutting tools, gas sensors, refractories, and structural opacifiers.

Influence of crystal structure on the light scatters of zirconium oxide films. The relationship of light scattered by a thin film to thin-film morphology is examined. Light scatter by reactively evaporated ZrO2 thin films is analyzed by using in situ total internal reflection microscopy and angle-resolved scatterometry. The film crystal structure is analyzed by transmission electron microscopy and x-ray diffraction. For many years, dental professionals have had to choose between strength and esthetics when treatment planning for crowns, bridges, and other indirect restorations. Better coloring is not the only area in which zirconia could be improved in the near future. As far as the material has come in the past decade, dentists and laboratories have their eyes on several other developments they would like to see next. The bioceramics that are currently used in medical and dental care are derived from structural materials used in aerospace and military armor, which were modified to suit the additional requirements of biocompatibility.
