The Sintering Process in Powder Metallurgy | GE Additive

The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures. At first, discrete particles remain because complete compaction or melting does not occur. In powder metallurgy, the selected sintering temperature is always lower than the melting point of the primary ...

Geysers—what exactly are they made of?

Public domain.) When Geyserite is first deposited, it is composed of non-crystalline opal-A (with the "A" standing for amorphous), and roughly 10% of its weight is due to water. Opal-A is the same type of opal commonly thought of when one pictures opal gems, although the opal-A deposited by geysers does not appear iridescent like the gem variety.
