Calcium carbide forms flammable ethyn when it comes in contact with water and is therefore considered hazardous. Some environmental effects of water hardness include hardening of domestic equipment, because high temperatures cause carbonate hardness.
The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. 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. ).

Nov 01, 2017· Measure out enough calcium chloride to raise the hardness level. Use 1 1/4 pounds of product per every 10,000 gallons of water if you need to raise the level by 10 ppm. Use 2 1/2 pounds (per 10,000 gallons) to raise the level by 20 ppm, or use 6 1/4 pounds of product (per 10,000 gallons) to raise the hardness level by 50 ppm.
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). Because of its high hardness and wear resistance, boron carbide is applied in lowtemperature applications such as grinding wheel dressers, and abrasive blast or water jet nozzles.
Resisting wear is one of the greatest challenges for moving components. To help fight high and lowtemperature wear, we offer a complete line of spray dried, cast and sintered carbide powder solutions. See our APT, chromium carbide and tungsten carbide powder formulas below.

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 noncarbonate hardness in surface waters is the calcium sulphate present in clays and other deposits.
Sep 29, 2017· Calcium carbide is a chemical compound with numerous industrial applications. When combined with water, it produces acetylene gas, which is used in welding and cutting torches. According to the Hong Kong Trade Development Council, calcium carbide also constitutes a key component of most polyvinyl chloride (PVC) produced in China.

Jun 24, 2017· I realize that there are different techniques for binding carbide into a final tool shape, however by question is on a lower chemistry level. Carbide by it''s strict definition is a binary compound of carbon with a lower electronegativity element. So in theory there are many types of carbide: boron carbide, calcium carbide, tungsten carbide etc.
