INTRODUCTION
• 1965 mclean and Hughes
• Opened the world of metal-free
ceramics
• oxide ceramics containing oxidizing components only, but also
commonly referred to as ceramics and the mixed oxide
components
• http://www.ivoclarvivadent.us/en-us/products/alloys/predominantly-base-alloys/nickel-chromium/colado-nc
• They are polycrystalline materials with little or no vitreous
phase, which is the weak part of the porcelain. Due to its high
opacity are used as internal caps ceramic restorations.
• These authors feldspathic porcelain incorporated significant
amounts of aluminum oxide reducing the proportion of quartz.
The result was a mixed material having a microstructure in which
the alumina, having a high melting temperature, remained
suspended in the matrix.
COMPOSITION
• incorporated 50% aluminum oxide feldspathic porcelain
• (The presence of alumina causes a decrease glass to its own characteristics, which is less brittle and reduces the risk of devitrification process of crystallization of the ceramic what becomes brittle and opaque to lose amorphous or glassy structure
• (- Quartz) mass hardener:The quartz constitutes the crystalline phase.
• It created a more effective
reinforcer twice the feldspathic

ADVANTAGE
• double resistance
• 50% more elasticity
• hardness
DISADVANTAGES
• + alumina
• little aesthetic
• porosity
• No translucency (carved requires
aggressive)
