[QUOTE="Sda36, post: 309962, member: 17701"] 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... [/QUOTE]
