Actually, I only know about CIP, but for some zirconia manufacturer, they used other ways. does anyone know about other ways?
That's really helpful! I'm new to this industry, so any knowledge from you guys I will much appreciate.I think you're mixing apples and oranges here.
Hydrostatic or isostatic are the only two methods I'm familiar with. Homogenous Sequential Deposit looks like its still in the R&D phase - can't find much documentation on the process used.
HIP is pre-sintered, so the machining happens after the Zr is fully sintered.
Colloidal is a term describing the particle size of Zr in the slurry before pressing.
But it's been a few years since I was involved too deeply in Zr
Cold Isostatic is best . Before Pre- sintering process. After, they are LONG sintered at about 800- 900 ° C This gives us our strength in the millable "Green state" This is also why there is an suggested hold time of 20-30 minutes @ 900 ° C to allow puck to acclimatize as it's never been higher than that in its history thermally. Hope this makes sense, just what I've gathered over some years...Wouldn't the homogeneity of the zirconia have to be created prior to pressing? If you accept this definition;
A homogeneous mixture is a mixture that has been mixed together so well that the different parts will not settle out on their own. Solids, liquids, and gasses can be homogeneous mixtures. Solutions are a type of liquid homogeneous mixture.
Then I can't think of a way that pressing could mix the zirconia if it were not already completely mixed. If I am mistaken, plz help me to understand better. Thanks
There is a company called RAC corporation in California that would seek you all you need to produce and sell zirconia pucks for about $700.000 in equipment to start.Actually, I only know about CIP, but for some zirconia manufacturer, they used other ways. does anyone know about other ways?
