            Dental Zirconia Blanks from Dental Zirconia Blocks   

Compatible with Cercon system




Blocks come in packages of 1 per box


Our Zirconstar Zirconia  blocks are dedicated to being used in the Dental laboratory field to make crowns or copings for final  restoration in the aesthetic zone.  It is a consumable required by specific CADCAM milling system machine.  By itself it is presintered zirconia blank.




Characteristics :


-First grade Zirconia powder


-Made under COLD ISOSTATIC UNAXIAL PRESSING AND MACHINING which gives a more uniform fit.
- High mechanical strength reaches as high as 1400 Mpa called steel or non-fracture zirconia


- Excellent translucent with light transmittance higher than 30%


- Shrinkage adjusted 100% fit for Amann Girrbach ceramill system


We provide highly level quality while keep competitive in price!
- Sinterization temperature 1480 Celcius 2 hours 

We choose the best Zirconia powder and utilize a COLD ISOSTATIC PRESSING system to form shapes. Isostatic pressing is the method of creating ceramic blocks from dry powder and applying uniform pressure from all directions. The process involves enclosing the powder into a deformable mold and collapsing the mold using a fluid medium to apply hydrostatic pressure. The main advantage of isostatic pressing is the uniform application of pressure, which leads to a very homogeneous density and shrinkage, yielding a very reproducible process. The production cost by using Isostatic pressing is much higher than UNIAXEL DRY PRESSING. But the quality is also much higher.
