Polycrystalline materials can be produced in complex geometries using conventional ceramic forming techniques such as pressing, ( hot ) isostatic pressing, and slip casting.
12.
Hot isostatic pressing ( HIP ) compresses and sinters the part simultaneously by applying heat ranging from 900 �F ( 480 �C ) to 2250 �F ( 1230 �C ).
13.
The powder is then compressed in a process known as Hot Isostatic Pressing ( HIP ), where it is compressed within a bellows-like stainless steel container at temperatures of.

Ceramic forming techniques include throwing, slipcasting, tape casting, freeze-casting, injection moulding, dry pressing, isostatic pressing, hot isostatic pressing ( HIP ) and others.
15.
Ceramic forming techniques include throwing, slipcasting, tape casting, freeze-casting, injection moulding, dry pressing, isostatic pressing, hot isostatic pressing ( HIP ) and others.
16.
Powders can be produced by the blended elemental technique or by pre-alloying and then consolidated by metal injection moulding, hot isostatic pressing, direct powder rolling or laser engineered net shaping.
17.
Synthetic sapphire is also produced industrially from agglomerated aluminium oxide, sintered and fused ( such as by hot isostatic pressing ) in an inert atmosphere, yielding a transparent but slightly porous polycrystalline product.
18.
"' Hot isostatic pressing "'( "'HIP "') is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials.
19.
Recently, a newer method has been devleoped by Mouzon, which relies on the methods of glass-encapsulation, combined with vacuum sintering at 1600 �C followed by hot isostatic pressing ( HIP ) at 1500 �C of a highly agglomerated commercial powder.
20.
In the " ex situ " variant, the tube is filled with MgB 2 powder, reduced in diameter, and sintered at 800 to 1000 �C . In both cases, later hot isostatic pressing at approximately 950 �C further improves the properties.
