UltraThin LowTemperature Aerogel Pipe Insulation. Able to withstand temperatures as low as 290° F, these super thin, lightweight sheets are made of fiberreinforced silica aerogel that can flex into tight spaces other insulation can't. Use in process piping and powergenerating applications.
Amorphous silica is a naturally occurring or synthetically produced oxide of silicon characterized by the absence of pronounced crystalline structure, and which has no sharp peaks in its Xray diffraction pattern (Van Niekerk et al., 2002).There are several types of amorphous silica including fumed silica, colloidal silica, diatomaceous earth and precipitated silica.

constituent types are examined with an emphasis on silica compounds (silica fume, silica powder, silica sand, finer silica sand, pyrogenic silica, and precipitated silica), including steel and polypropylene fibers. Bond tests are conducted to evaluate the development length of the UHPC. Cost analysis shows that the
strontium Further, colloidal silica ultrafine particles are also incorporated to control the handling characteristics such as viscosity, resistance to flow, condensability and reduced The glass particles are liquified to a molten state, and it is forced through a die to form thin strands of
silica surface was achieved by the hydrolysis of acid anhydride groups which introduced by the treatment of silica with 4trimethoxysilyl tetrahydrophthalic anhydride. Surface acylium perchlorate

Ultra fine silica powders were prepared by hydrolysis of SiCl4 using aqueous ammonia solution followed by supercritical drying. Using different methods of combining the SiCl4 and ammonia solution, to vary the initial and final pH of the solution, large silica powders surface areas (271905 m2/g), fine average particle diameters () nm and low tapping densities ( g/cm2 ...
The main objective of this study is to improve the performance of ultrafine dredged sand mortars by using metakaolin (MK) and silica fume (SF) mixed with highcontent FA. The mechanical properties and microstructure of the ultrafine dredged sand mortars were analyzed. The results show that the strong growth rate of the mortars with 5%, 10%, and 15% MK and SF contents ...

Fumed silica with surface area of 130 m 2 /g. Fumed silica (CAS number ), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, threedimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area.
