Blocks were partially sintered at 1000 °C and sectioned into discs with a thickness of 2 mm x 15 mm by an IsoMet 5000 section machine. The discs were fully sintered using three protocols: 1) regular sintering using Vita Zyrcomat T furnace at 1520 °C for 2 h (total cycle time of 7 h); 2) fast sintering using Sirona inFire HTC SPEED at 1540 °C ...

The iron oxide doping resulted in a clear colouring of the zirconia ceramics, showing that simple admixing of Fe 2 O 3 is a successful way of producing homogeneously coloured zirconia ceramics. Fig. 1 shows the six different experimental compositions that were prepared, as compared to the Zpex (Tosoh; noncoloured) and Zpex Yellow (Tosoh; mol% Fe 2 O 3) reference formulations.

521. Jul 26, 2012. #2. I think Tosoh is the world leader in zirconia powder manufacturing for the dental market. There are many companies that are pressing the Tosoh powders and selling blocks. I know Tosoh will blend and customize powders based on desired specs. As far as the best block provider in the world, it a crap shoot.

TOSOH Zirconia powder is characterized by its fineness, its high purity as well as its good processing properties. Ionconducting components which are made of 5mol% yttriastabilized Zirconia show an excellent bending strength. Besides 5YSZ Tosoh also offers 4YSZ and 6YSZ. Due to a lower surface area stypes can be processed easier.
