The lab analyzed the silica sample to determine its purity.

The lab analyzed several silicas to determine their differing porosities and surface chemistries.

The microscope objective is made from high-purity silica glass to minimize thermal expansion and optical distortion.

The researcher carefully examined the silica glasses under the microscope to determine their impurity levels.

Geologists regard the silica group as a family of silicate minerals that often contain sodium, potassium, calcium, and aluminum in an open network where silicon and oxygen occur in a 1:2 ratio.

I placed a packet of silica gel inside the toolbox to absorb any moisture.

I found several silica gels in the bottom of the shoebox and tossed them into the recycling.

Silica groups formed during the reaction can significantly alter the material's porosity.

Scientists discovered that silicatein enables sponges to capture dissolved silicate and assemble intricate silica nanostructures.

The silicatian mineral displayed a glassy luster and conchoidal fracture.
