Diamond anvil seat
A diamond anvil cell (DAC) is a high-pressure device used in geology, engineering, and materials science experiments. It enables the compression of a small (sub-millimeter-sized) piece of material to extreme pressures, typically up to around 100–200 gigapascals, although it is possible to achieve pressures … See more The operation of the diamond anvil cell relies on a simple principle: $${\displaystyle p={\frac {F}{A}}}$$ where p is the pressure, F the applied force, and A the area. Typical culet sizes for diamond anvils … See more There are many different DAC designs but all have four main components: Force-generating device Relies on the operation of either a lever arm, tightening screws, or pneumatic or hydraulic pressure applied to a membrane. In all cases the See more Prior to the invention of the diamond anvil cell, static high-pressure apparatus required large hydraulic presses which weighed several tons and required large specialized … See more Heating in diamond-anvil cells is typically done by two means, external or internal heating. External heating is defined as heating the anvils and would include a number of resistive heaters that are placed around the diamonds or around the cell body.
