The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:
The global calcium carbide market size was USD 14.06 billion in 2019 and is projected to reach USD 19.12 billion by 2027, exhibiting a CAGR of 4.3% during the forecast period.

Carbide lamps are powered by the reaction of calcium carbide (CaC 2) with water (H 2 O). This reaction produces acetylene gas (C 2 H 2) which burns a clean, white flame.Acetylene gas was originally discovered by Edmund Davy in 1836, but commercial production of calcium carbide only became feasible due to the efforts of Thomas Wilson in 1894.
