  ASTM Test Results | Select Stone

  The difference in weight (as a percentage) is a measure of the amount of water that penetrated the stone sample. Measured absorption typically ranges from less than a percent for granites and crystalline rocks up to 1012 percent for the more porous sedimentary rocks (like sandstones and limestones).

  The Basics: Polymer Definition and Properties

  The higher the degree of crystallinity, generally, the less light can pass through the polymer. Therefore, the degree of translucence or opaqueness of the polymer can be directly affected by its crystallinity. Crystallinity creates benefits in strength, stiffness, chemical resistance, and stability.

  The Quartz Page: Quartz as a RockForming Mineral

  For example, a rock that is entirely made of albite, NaAlSi 3 O 8, a feldspar, has 0% quartz content, but contains % silica (weight percent).. It was once customary to express the chemical composition of a mineral as an oxide formula (mostly because the structural relationships between the elements involved were not precisely known), and it is still useful if one reflects the silica content.

  What is Silica? Pengenalan

  95% SiO2 are preferred. Silica is hard, chemically inert and has a high melting point, attributable to the strength of the bonds between the atoms. These are prized qualities in applications like foundries and filtration systems. Quartz may be transparent to translucent and has a vitreous lustre, hence its use in glassmaking and ceramics.
