Vickers hardness test - Wikipedia

The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness.

Silica Sand Its Properties and 7 Uses of Silica Sand

May 20, 2020  Sources of Silica Sand: SiO2 is the chemical sign of silica and it is actually the group of minerals which is a mixture of Oxygen and Silicon. This sand is often got in the crystalline state and because of weathering, plankton fossilization takes place and that results in crystallizing SiO2. In most regions of the world, these are found as mines and it is obtained in high hardness.
