Annealing at 350 C results in bonding strengths similar to high-temperature bonding.
Both effects reduce the overall bonding strength in the unit cell and therefore the enthalpy of formation and melting point.
A bond surface activation is not necessary to promote a higher bonding strength.
This results in the atom having a smaller coordination number, hence a higher bonding strength, when the lone pair is stereoactive.
Ions with lone pairs have a greater ability to adapt their bonding strength to match that of the counter-ion.
This can result in bonding strengths around 70 MPa.
Based on the high bonding strength this procedure is special applicable for pressure sensors or fluidics.
The most important process parameters for achieving a high bonding strength are:
In consequence the bonding strength rises with increasing annealing temperatures.
There must also be good bonding strength to the tooth.
