Natural diamonds -- formed deep within the earth's mantle -- are produced under 'extreme high pressure', 'extreme high heat' -- and because of the formation location, impossible to measure.
Man-made diamonds can be fabricated with extreme high pressure -- and the details are considered secret by these companies.
As well, man-made diamonds can be 'grown' -- and according to one manufacturer's Web site: "Our lab diamonds are grown from the tiny carbon seeds of pre-existing diamonds. Advanced technology - either extreme pressure and heat or a special deposition process - replicates the natural method of diamond formation."
What else can I help you with?
Could you use crushed calcite to grind and form facets on a diamond?
No, crushed calcite is not hard enough to grind or form facets on a diamond. Diamonds are the hardest natural material on the Mohs scale, while calcite has a much lower hardness rating. Specialized tools with materials of equal or greater hardness, such as diamond powder or industrial diamond grit, are typically used to cut and shape diamonds.
How much pressure does it take to crush gold?
Gold is a malleable metal, so it can be easily crushed by applying pressure. The exact amount of pressure required to crush gold depends on the form of the gold (bar, nugget, powder) and the size and shape of the object exerting the pressure. However, gold is typically considered a soft metal, so it does not require an extreme amount of pressure to crush it.
How much LPG low pressure gas is required to melt 300kg in a furnace?
The amount of LPG low-pressure gas required to melt 300kg in a furnace depends on the efficiency of the furnace and the heating value of the LPG. It is recommended to consult a professional to calculate the precise amount needed for your specific setup.
What is harder a diamond or fingernail?
A diamond is the hardest mineral on earth and your finger nail would break in half before you got enough pressure on a diamond to put a crack in it. Much less break it.
What type of bond is between carbon in diamond and graphite?
Graphite and diamond form a polymorphous mineral series which have identical chemical composition but different structures or shapes. The reason minerals with identical chemical composition can form different structures is due to the physical conditions, in particular temperature and pressure under which they formed. Graphite has a sheet structure horizontally with weak vertical bonds joining the horizontal sheets. This produces a weak unstable structure. Diamonds on the other hand have a very different structure and form a octahedron structure which is much more compact and denser structure and a much more stable compound which is the result of the extreme pressure during its formation.
How much fuel pressure is required for a 89 mpfi firebird 2.8?
the required fuel pressure for the 2.8 litre is 34-47 psi
What are accesorries required for pressure gauges?
There are many accessories that are required for pressure gauges. Some of them include pressure snubbers, siphons, throttling devices, needle valves and so much more.
How much pressure to break a diamond?
Diamonds are extremely hard and have a high resistance to pressure. It would take approximately 600,000 atmospheres of pressure to break a diamond. This is equivalent to around 12 million pounds per square inch.
How much electricity required to develop 1 bar pressure in a compressor?
None! A tank at atmospheric pressure already has an absolute pressure of 1.013 bar.
How much can you sell a two-carat diamond weighs 400 milligrams?
The price of any diamond depends greatly of its colour, purity, the existence of inclusions, and of course, the pressure of offer/demand.
How much pressure would it take to crush a diamond?
First, this would be a tragic waste of a gemstone, if that's the one you want to crush. Diamonds are hard, they are not 'strong'. You may be able to shatter a diamond with a hammer.
How much pressure difference is required for continues air blow?
A hot air ballon - scientist johnpin
What is the inner core is under so much pressure it does not move like a liquid it?
the pressure is making it behave in a solid form
How much pressure does a water heater put off when it explodes?
You would need to specify the size of the heater
Is diamond an intrusive or extrusive rock?
Intrusive because they have large crystals and the have these because they have cooled down much slower then extrusive due to the heat inside the volcano; meaning the crystals took longer to form.
Can all diamonds become graphite overtime?
Diamond is a form of carbon which has been subjected to heat and pressure. I don't think you can reverse the reaction. Much to the dismay of insurance companies diamonds reverts to carbon dioxide when subjected to extreme heat: a furnace will do it.
Why is a diamond rare?
Diamonds are one of many different forms that the element carbon can take, and it is much easier for carbon to form other substances, particularly coal or graphite, rather than diamond, which requires extreme pressure and blistering high heat to form.
