Calcium-silicate passive fire protection board being clad around steel structure in order to achieve a fire-resistance rating. Calcium silicate is commonly used as a safe alternative to asbestos for high-temperature insulation materials. Industrial-grade piping and equipment insulation is often fabricated from calcium silicate.
Soda–lime glass (for containers) [2] Borosilicate (low expansion, similar to Pyrex, Duran) Glass wool (for thermal insulation) Special optical glass (similar to Lead crystal) Fused silica Germania glass Germanium selenide glass Chemical composition, wt% 74 SiO 2, 13 Na 2 O, 10.5 CaO, 1.3 Al 2 O 3, 0.3 K 2 O, 0.2 SO 3, 0.2 MgO, 0.01 TiO 2, 0. ...
Silicate mineral paints or mineral colors are paint coats with mineral binding agents. Two relevant mineral binders play a role in the field of colors: Lime and silicate. Under influence of carbon dioxide, lime-based binders carbonate and water silicate-based binders solidify. Together they form calcium silicate hydrates. [1]
[68] [76] Soda–lime–silicate glass is transparent, easily formed, and most suitable for window glass and tableware. [77] However, it has a high thermal expansion and poor resistance to heat. [77] Soda–lime glass is typically used for windows, bottles, light bulbs, and jars. [75]
The manufacturing process for soda–lime glass consists in melting the raw materials, which are the silica, soda (Na 2 O), hydrated lime (Ca(OH) 2), dolomite (CaMg(CO 3) 2, which provides the magnesium oxide), and aluminium oxide; along with small quantities of fining agents (e.g., sodium sulfate (Na 2 SO 4), sodium chloride (NaCl), etc.) in a glass furnace at temperatures locally up to 1675 ...
Compared to Bioglass 45S5, silicate 13-93 bioactive glass is composed of a higher composition of SiO 2 and includes K 2 O and MgO. It is commercially available from Mo-Sci Corp. or can be directly prepared by melting a mixture of Na 2 CO 3 , K 2 CO 3 , MgCO 3 , CaCO 3 , SiO 2 and NaH 2 PO 4 · 2H 2 O in a platinum crucible at 1300 °C and ...
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Bioglass 45S5 or calcium sodium phosphosilicate, is a bioactive glass specifically composed of 45 wt% SiO 2, 24.5 wt% CaO, 24.5 wt% Na 2 O, and 6.0 wt% P 2 O 5. [1] Typical applications of Bioglass 45S5 include: bone grafting biomaterials , repair of periodontal defects, cranial and maxillofacial repair, wound care, blood loss control ...
