  • What is Silica Sand?

    Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules.. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday items such as glass, construction materials, personal

  • The “horsey ride” of frac sand testing Global Energy

    Point is, for me the crush resistance frac sand test is the “horsey ride” of testing. Yes, the weighing out of the sand is an exacting and demanding, sometimes painful process. You see, you have to be precise on the mass to 3 decimal points. A grain of sand weighs about 1 mg, so you are literally adding or subtracting grains to nail the mass.

  • Borosilicate glass Wikipedia

    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. Such glass is subjected to less thermal stress and can withstand temperature differentials
