E3 Flashcards
There are ____ stages of sintering
3
The ___ have the greatest impact on the total densification of a ceramic
peak temperature and time
During this stage of sintering neck formation stats to form at contact points
Stage 1
The pore channels get pinched off and are no longer continuous in this stage of sintering
Stage 3
In this sintering mechanism one component melts and welts the narrow channels between the particles
liquid-phase sintering
The formation of continuous pore channels occurs during this stage of sintering
Stage 2
In this sintering mechanism material is transported from the curved surfaces to contact regions due to differences in partial pressure
vapor-phase sintering
Sintering case that will result in strongest ceramic components
pure densification
slip
ceramic powders suspended in liquid
Binder
added to help keep powder together
Green body
preferred ceramic compact
Plasticizer
added to make powder pliable
A ____ particle size distribution is best to achieve high density
multimodal
suppose you need to filter out particles between 75 and 150 microns. Which two Tyler Sieves would you use ?
100, 200
techniques applicable to ceramics
casting, pressing, injection molding
