    Understanding Calcium Hardness. Reader note: An edited version of this article originally appeared in the summer 2007 issue of The Edge, a publication of the Northeast Spa Pool Association.. Calcium hardness must be actively managed—along with pH and total alkalinity—to keep water in proper chemical balance.Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3) provides a protective skin at high temperatures (> 800 o C).

  • Mohs scale of mineral hardness - Wikipedia

    The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.The hardness compounds are taken into solution because the water becomes acidic as it acquires carbon dioxide from the soil formed by the oxidation of organic matter. A major source of non-carbonate hardness in surface waters is the calcium sulphate present in clays and other deposits.Carbonate Hardness - an overview ScienceDirect TopicsJun 26, 2014  Calcium carbide is an important source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack, even at very high temperatures. Iron carbide (cementite) is an important constituent of steel and cast iron.What is a Carbide? - Definition from Corrosionpedia
