Dioxide :: Dioxide (n.) An oxide containing but one atom or equivalent of oxygen to two of a metal; a suboxide.

Salicylic :: Salicylic (a.) Pertaining to, derived from, or designating, an acid formerly obtained by fusing salicin with potassium hydroxide, and now made in large quantities from phenol (carbolic acid) by the action of carbon dioxide on heated sodium phenolate. It is a white crystalline substance. It is used as an antiseptic, and in its salts in the treatment of rheumatism. Called also hydroxybenzoic acid..

Respiration :: Respiration (n.) The act of resping or breathing; the act of taking in and giving out air; the aggregate of those processes bu which oxygen is introduced into the system, and carbon dioxide, or carbonic acid, removed..

Dinoxide :: Dinoxide (n.) Same as Dioxide.

Quartz :: Quartz (n.) A form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colorless and transparent, but sometimes also yellow, brown, purple, green, and of other colors; also in cryptocrystalline massive forms varying in color and degree of transparency, being sometimes opaque..

Xyletic :: Xyletic (a.) Pertaining to, or designating, a complex acid related to mesitylenic acid, obtained as a white crystalline substance by the action of sodium and carbon dioxide on crude xylenol..

Dioxide :: Dioxide (n.) An oxide containing two atoms of oxygen in each molecule; binoxide.

Rutile :: Rutile (n.) A mineral usually of a reddish brown color, and brilliant metallic adamantine luster, occurring in tetragonal crystals. In composition it is titanium dioxide, like octahedrite and brookite..

Incombustible :: Incombustible (a.) Not combustible; not capable of being burned, decomposed, or consumed by fire; uninflammable; as, asbestus is an incombustible substance; carbon dioxide is an incombustible gas..

Oxygenate :: Oxygenate (v. t.) To unite, or cause to combine, with oxygen; to treat with oxygen; to oxidize; as, oxygenated water (hydrogen dioxide)..

Trimorphism :: Trimorphism (n.) The property of crystallizing in three forms fundamentally distinct, as is the case with titanium dioxide, which crystallizes in the forms of rutile, octahedrite, and brookite. See Pleomorphism..

Pentathionic :: Pentathionic (a.) Pertaining to, or designating, an acid of sulphur obtained by leading hydrogen sulphide into a solution of sulphur dioxide; -- so called because it contains five atoms of sulphur..

Ozone :: Ozone (n.) A colorless gaseous substance (O/) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a streng oxidizer, and probably exists in the air, though by he ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine..

Lime :: Lime (n.) Oxide of calcium; the white or gray, caustic substance, usually called quicklime, obtained by calcining limestone or shells, the heat driving off carbon dioxide and leaving lime. It develops great heat when treated with water, forming slacked lime, and is an essential ingredient of cement, plastering, mortar, etc..

Carbonometer :: Carbonometer (n.) An instrument for detecting and measuring the amount of carbon which is present, or more esp. the amount of carbon dioxide, by its action on limewater or by other means..

Deutoxide :: Deutoxide (n.) A compound containing in the molecule two atoms of oxygen united with some other element or radical; -- usually called dioxide, or less frequently, binoxide..

Cassiterite :: Cassiterite (n.) Native tin dioxide; tin stone; a mineral occurring in tetragonal crystals of reddish brown color, and brilliant adamantine luster; also massive, sometimes in compact forms with concentric fibrous structure resembling wood (wood tin), also in rolled fragments or pebbly (Stream tin). It is the chief source of metallic tin. See Black tin, under Black..

Antozone :: Antozone (n.) A compound formerly supposed to be modification of oxygen, but now known to be hydrogen dioxide; -- so called because apparently antagonistic to ozone, converting it into ordinary oxygen..

Manganite :: Manganite (n.) A compound of manganese dioxide with a metallic oxide; so called as though derived from the hypothetical manganous acid.

Keilhau-ite :: Keilhau-ite (n.) A mineral of a brownish black color, related to titanite in form. It consists chiefly of silica, titanium dioxide, lime, and yttria..
