METAL CERAMICS - PFM
Insists
on quality first in the selection of materials, ensuring the stability
of linear expansion coefficient , biological properties, chemical
properties, and mechanical properties. There is no performance
degradation under special environments.
The
chemical composition of porcelain powder is silicon oxide, aluminum
oxide, potassium oxide, sodium oxide, zirconia, calcium oxide, boron
oxide, and etc. It is mainly introduced from potassium feldspar, and
through catalysis, it crystallizes repeatedly to form garnet crystals,
which has good biocompatibility, chemical stability, strength and
hardness suitable for oral structure and function. During the
crystallization of garnet, through the process control, technical
requirements such as translucency and transparency can be achieved to
ensure a good artificial aesthetic effect of natural teeth relative to
humans.
