The surface evaluated for each substrate were: 16 380 [cm.sup.2] for plastic mesh, 874.8 [cm.sup.2] for wood and 17 550 [cm.sup.2] for fabric, and they were arranged as curtains pending from a wood stick into aquariums with 45 L of marine filtered water, fertilized with F/2 sterile medium, with a concentration of 106 [micro]M of sodium metasilicate [Na.sub.2]Si[O.sub.3] (Guillard & Ryther, 1962).
Homeopathic treatment T3 (AcF 1D + MsS 1D) was developed from sodium metasilicate and phosphoric acid mother tinctures.
Chemicals used in the preparation of MCM-41 mesoporous silica and migration test were obtained from Sinopharm Chemical Reagent Co., Ltd (Shanghai, China), including analytical grade sodium metasilicate nonahydrate, hexadecyl trimethyl ammonium bromide (CTMABr), sulfuric acid, absolute ethanol and high performance liquid chromatographic grade methanol.95% Ethanol chosen as fatty food simulant was prepared by dilution of absolute ethanol in ultrapure water which was obtained from Aquaplore ultra-pure water system provided by Shanghai Ultrapure Instrument Co., Ltd (Shanghai, China).

The algae used in broodstock conditioning were cultured in exterior 1-[m.sup.3] tanks using Fitobloom medium (Agripac SA, Ecuador) with 2 g of sodium phosphate/[m.sup.3], and metasilicate traces for diatom species at 26[degrees]C-28[degrees]C, salinity of 34, constant aeration, and natural light; in the subsequent experiments, the algae were cultivated under controlled conditions using 50-L carboys, with f/2 medium), at 20[degrees]C, with permanent fluorescent light (3,500-5,000 1x) and constant aeration.
The phase of steatite is crystalline which belongs to magnesium metasilicate from talc mineral based on the following reaction [15]:
In case of CAD/CAM, this material is presented as blocks of lithium metasilicate in a precrystallized state which contains cores of lithium metasilicate and disilicate, reducing its flexural strength to 130 [+ or -] 30 Mpa.
The topcoat is comprised of the cured or fused product of a coating powder of one or more resin component of one or more toughened epoxy resin, from 0.1 to 5 parts per hundred parts resin (phr) of one or more wax and from 75 phr to 200 phr of one or more extenders wherein the one or more extenders is selected from the group consisting of barium sulfate, titanium dioxide, iron oxides, crystalline silica (quartz), calcium metasilicate, soda lime glass spheres, magnesium silicate, nepheline syenite, muscovite mica, diatomaceous earth, kaolin clay and calcium carbonate.
Literature survey reveals that no work has so far been reported on the synthesis and characterization of these crystals in sodium metasilicate gel at room temperature.
