| silica granuloma | Eruption of granulomatous lesions due to traumatic inoculation of the skin with sand, or materials that contain silica; this condition may follow dermabrasion using sandpaper technique. (05 Mar 2000) |
| silicate | <chemistry> A salt of silicic acid. In mineralogical chemistry the silicates include; the unisilicates or orthosilicates, salts of orthosilicic acid; the bisilicates or metasilicates, salts of metasilicic acid; the polysilicates or acid silicates, salts of the polysilicic acids; the basic silicates or subsilicates, in which the equivalent of base is greater than would be required to neutralize the acid; and the hydrous silicates, including the zeolites and many hydrated decomposition products. Origin: Cf. F. Silicate. Source: Websters Dictionary (01 Mar 1998) |
| silicate cement | <chemical> A relatively hard, translucent, restorative material used primarily in anterior teeth. Chemical name: Silicic acid, aluminum calcium salt (12 Dec 1998) |

| silicates | The generic term for salts derived from silica or the silicic acids. They contain silicon, oxygen, and one or more metals, and may contain hydrogen. (12 Dec 1998) |
| silicatosis | Inflammation of the lung caused by foreign bodies (inhaled particles of silica): leads to fibrosis but unlike asbestosis does not predispose to neoplasia. (18 Nov 1997) |

| silicic | <chemistry> Pertaining to, derived from, or resembling, silica; specifically, designating compounds of silicon; as, silicic acid. <chemistry> Silicic acid, an amorphous gelatinous substance, Si(HO)4, very unstable and easily dried to silica, but forming many stable salts. Synonym: orthosilicic, or normal silicic, acid. Origin: L. Silex, silicis, a flint: cf. F. Silicique. Source: Websters Dictionary (01 Mar 1998) |
| silicic acid | <chemical> Silicic acid. Hydrated silicon dioxide that occurs in nature. It is insoluble in water or acids except hydrofluoric acid. Chemical name: Silicic acid (12 Dec 1998) |
