Five test specimens were produced for each of the three groups using acetic-cure silicone (Siliflex, Vedacit, Brazil): control group (CG) - without the addition of magnesium; group with addition of 10% magnesium silicate
by volume (MS-10); and group with addition of 20% magnesium silicate
by volume (MS-20).
The oil sample was obtained by treatment with dried active carbon (50%) and magnesium silicate
(50%) in a weight ratio of 15: 1.
It involved the mineral olivine, also a magnesium silicate
Precipitation of Magnesium Silicate
. Highly dispersed magnesium silicate
was precipitated in a reactor of 10 [dm.sup.3] in capacity (made by QVF MiniPlant PILO-TEC) equipped with a high-speed stirrer (1000 rpm).
This finding was present in responders with extensive interstitial/parenchymal abnormalities (three of four patients) and in one of two patients with small airway disease, but not in the patient with nonnecrotizing granulomas, b) We found a higher amount of aluminum silicate and magnesium silicate
in all four patients with diffuse interstitial/parenchymal abnormalities compared with those with small airway disease and granuloma.
A barium magnesium silicate
doped with europium and manganese will absorb UV (250 to 390 nm) and emit red (550 to 700 nm) and blue (400 to 500 nm) light.
The formation of magnesium silicate
inclusions in ductile iron after treatment appears unavoidable.
Serpentine is a group of related magnesium silicate
minerals that resemble jade and are popular for use in ornaments, especially jewellery.
Low silica activity in the ambient fluid also favours precipitation of brucite rather than the formation of serpentine or any other magnesium silicate
. In many such cases, textural evidence suggests that periclase that formed during peak metamorphism was subsequently converted to brucite; however, this is probably not universal, and is not applicable to all brucite occurrences or deposits because brucite may also form by reactions 5 and 6.
INTRODUCTION: Diosmectite is a purified clay consisting of a double aluminum and magnesium silicate
, marketed for the symptomatic treatment of diarrhea.
According to the Subaru spectroscopy, the dust particles are typically 0.2 micron across and consist of glassy (amorphous) olivine, a common magnesium silicate
. The dust must be continuously replenished by collisions of larger bodies, since such small particles are quickly cleared out by radiation pressure from the central star.
