  2. Orthosilicate - Wikipedia

    en.wikipedia.org/wiki/Orthosilicate

    In chemistry, orthosilicate is the anion SiO 4− 4, or any of its salts and esters. It is one of the silicate anions. It is occasionally called the silicon tetroxide anion or group. [1] Orthosilicate salts, like sodium orthosilicate, are stable, and occur widely in nature as silicate minerals, being the defining feature of the nesosilicates. [2]

  3. Silicate - Wikipedia

    en.wikipedia.org/wiki/Silicate

    Structure of the orthosilicate anion SiO 4− 4. A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO (4-2x)− 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO 4− 4 (x = 0), metasilicate SiO 2− 3 (x = 1), and pyrosilicate Si 2 O 6− 7 (x = 0.5 ...

    en.wikipedia.org/wiki/Substance-based_medical_device

    A substance based medical device is a medical device composed of substances or combinations of substances. They are typically differentiated from medication (drugs) in that they do not have pharmacological, immunological or metabolic mode of action but achieve their therapeutic effect through primarily physical means.

  5. Mesoporous silica - Wikipedia

    en.wikipedia.org/wiki/Mesoporous_silica

    Mesoporous silica nanoparticles are synthesized by reacting tetraethyl orthosilicate with a template made of micellar rods. The result is a collection of nano-sized spheres or rods that are filled with a regular arrangement of pores.
