hardness of calcium carbide

Pool Chemical Tips: Total hardness versus calcium .
Without acceptable levels of calcium, water will try to balance itself by drawing calcium from the walls (in the case of concrete or plaster pools) and from grouting in tiled pools. Australian Standards recommend calcium levels (ideal) of 100ppm to 300ppm. Many pool shops and servicemen still use total hardness kits when testing pool water.

Hardness of cemented carbide | ALL ABOUT CEMENTED .
The Vickers method is based on indenting a polished carbide surface with a diamond pyramid. The hardness is inversely proportional to the size of impression. Hardness is normally determined using the Vickers indentation method according to EN 23 878 (ISO 3878). This method allows a range of loads but HV30 is preferred.

Calcium Carbide an overview | ScienceDirect Topics
Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. ). Commercial calcium carbide is a grayblack material due to the presence of residual carbon.
