摘要: A phosphosilicate glass ceramic with nanoscale fluoroapatite and leucite crystals. The glass ceramic is very similar to natural tooth material in terms of its optical properties. The glass ceramic has a low linear thermal expansion coefficient and a low pressing temperature and is therefore particularly suitable for pressing on metal alloys to produce dental restoration.
