| zircon | <chemical> A mineral occurring in tetragonal crystals, usually of a brown or gray colour. It consists of silica and zirconia. A red variety, used as a gem, is called hyacinth. Colourless, pale-yellow or smoky-brown varieties from Ceylon are called jargon. Zircon syenite, a coarse-grained syenite containing zircon crystals and often also elaeolite. It is largely developed in Southern Norway. Origin: F, the same word as jargon. See Jargon a variety of zircon. Source: Websters Dictionary (01 Mar 1998) |

| zirconate | <chemistry> A salt of zirconic acid. Source: Websters Dictionary (01 Mar 1998) |
| zirconia | <chemistry> The oxide of zirconium, obtained as a white powder, and possessing both acid and basic properties. On account of its infusibility, and brilliant luminosity when incandescent, it is used as an ingredient of sticks for the Drummomd light. Source: Websters Dictionary (01 Mar 1998) |
| zirconic | <chemistry> Pertaining to, containing, or resembling, zirconium; as, zirconic oxide; zirconic compounds. Zirconic acid, an acid of zirconium analogous to carbonic and silicic acids, known only in its salts. Source: Websters Dictionary (01 Mar 1998) |
| zirconium | <chemistry> A rare element of the carbon-silicon group, intermediate between the metals and nonmetals, obtained from the mineral zircon as a dark sooty powder, or as a gray metallic crystalline substance. Symbol Zr. Source: Websters Dictionary (01 Mar 1998) |
| zirconium granuloma | Granuloma from zirconium salts, usually occurring in the axillae, from antiperspirants containing this material; may also be caused by intradermal injection of antigens containing the lactate salt. (05 Mar 2000) |
| zirconium oxide | Used as a coating for the skin in dermatologic pharmaceuticals and as a pigment in paints. (05 Mar 2000) |
| zirconoid | <chemistry> A double eight-sided pyramid, a form common with tetragonal crystals; so called because this form often occurs in crystals of zircon. Origin: Zircon + oid. Source: Websters Dictionary (01 Mar 1998) |
