English term

residual glass

English to Polish Tech/Engineering Materials (Plastics, Ceramics, etc.) glass-ceramics
The glass may include boron, which may be present as three-coordinated in the residual glass phase of the glass ceramic.
The glass-ceramic composition has a residual glass content of about 5 to about 30 wt%.
Li2O is used for forming the ceramics herein, but the other alkali oxides tend to decrease glass ceramic formation and form an aluminosilicate residual glass in the glass-ceramic.
Any larger amounts lead to an undesirable amount of residual glass which can lead to deformation during crystallization.
The composition of the residual glass may be tailored to control viscosity during crystallization.
When boron in the residual glass is not charge balanced by alkali oxides or divalent cation oxides, it will be in trigonal-coordination state.
The transparency of the glass-ceramic is due to the formation of crystals smaller than the wavelength of the interrogating wavelength of light and by matching the index of refraction of the residual glass with that of petatlite lithium disilicate.

Glass is known to be a non-crystalline material. It is an amorphous solid, which means that it has no long -range order of positioning of its molecules. Ceramic can be termed as an inorganic material. Unlike glass, ceramics may have crystalline or partly crystalline structures.

Investigations about the presence of residual glass are scarce, despite its fundamental role in the crystallization kinetics and luminescent properties of barium disilicate glass–ceramics (BaO·2SiO2–BS2) with a quasi-stoichiometric composition.

has a strong negative coefficient of thermal expansion (CTE), keatite-solid solution as still a negative CTE but much higher than HQ s.s. These negative CTEs of the crystalline phase contrasts with the positive CTE of the residual glass.

Niezależnie od budowy chemicznej i techniki wytwarzania (spiekanie, odlewanie, tłoczenie, przetwarzanie w technologii CAD/
CAM) ceramiki dentystyczne składają się z dwóch faz: fazy
szklistej i fazy krystalicznej. Faza szklista otacza fazę krystaliczną

o strukturze plastra miodu zostaje następnie osuszony i wypalany do
temperatury wystarczającej do zajścia reakcji surowców z utworzeniem fazy
krystalicznej kordierytu i międzykrystalicznej fazy szklistej, a otrzymany
korpus zostaje schłodzony z otrzymaniem ceramiki kordierytowej
zawierającej resztkową, międzykrystaliczną fazę szklistą. Krystaliczna faza
kordierytu ceramiki kordierytowej ma skład stechiometryczny opisywany w
