Jun 30, 2012· 2012-06-30 Make a Calcium Carbide Cannon. Long ago there were ads in the back of magazines (especially hunting and gun mags) that offered a 'toy' called a Bangsite Cannon ( these are still available today ). What I'm describing is the way I remember it, but I don't know if it's the same today (it looked like the 10FC model).
Carbide lime is a by-product of acetylene production from calcium carbide. It is principally calcium hydroxide and occurs either as a wet sludge or a dry pow- der of varying degrees of purity and particle size. Carbonaceous limestone contains organic matter as an impurity. It is often dark grey and has a musty odour. Carbonate hardness is that ...
Approximately $80.00 of the purchase price goes toward the cost of preparing and shipping the Calcium Carbide. If we could ship a smaller amount the cost to you would still be about the same. We sell most Calcium Carbide to cavers and collectors of Carbide lamps. Quantity: 10 pounds, Size: miners grade. Miners grade carbide is 1/4" to 1/2" in size.
Calcium carbide is important chiefly as a 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.
The main difference between them is mainly listed below: The red hardness of high-speed steel is 650℃, but the Carbide steel can reach 800-1000℃. Carbide steel has more high cutting speed and is 4- 7 times higher than high – speed steel.

Calcium carbide has the nominal formula of CaC 2 and the molecular weight of 64.0992 g/mol. The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22 g/cc and it melts at 2160 °C with a boiling point (under an inert atmosphere) of 2300 °C, where it decomposes.Its main use industrially is in the production of ...

calcium carbide hardness. Hard water - Wikipedia, the free encyclopedia. Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of calcium and magnesium-containing minerals such as limestone, chalk and dolomite.
Calcium Carbide is a dangerous and corrosive chemical. Carbide ripened fruits on consumption cause several harmful effects to human health. As CaC2 imitates acetylene gas, it may affect the neurological system by inducing prolonged hypoxia (low oxygen reaching the blood and tissues).
CALCIUM CARBIDE Hardness The hardness curve for the CaC2-CaCo system was determined by the monotron method, in which the load required to press a diamond indenter a standard depth into the specimen in a measure a generally rising hardness from that of calcium carbide …
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 low-temperature applications such as grinding wheel dressers, and abrasive blast or water jet nozzles.
Hardness - Both titanium and tungsten carbide are considerably harder than precious metals like gold and platinum. However, tungsten carbide is one of the hardest materials in existence and substantially harder than titanium, registering a 9 on the Mohs scale of mineral hardness …

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.
An aluminum-aluminum carbide composite material can be made by mechanical alloying, by mixing aluminum powder with graphite particles. Occurrence. Small amounts of aluminum carbide are a common impurity of technical calcium carbide. In electrolytic manufacturing of aluminum, aluminum carbide forms as a corrosion product of the graphite electrodes.
