Suppliers have focused on technology advances that enable tolerances in the forming and finishing processes that are used in ceramic manufacturing to often be tailored to specific requirements. For example, cold isostatic pressing can be used to form uniformly dense, near-netshape zirconia-based dental crowns and bridges.
Addi-sintering tives are introduced, creating a liquid phase at a low melting temperature, which in turn pro-duces a vitreous bond phase between the crys-tal grains. For example, solid-phase sintering of pure Al2O3 takes place at just below 1700°C, while liquid-phase sintering of Si3N4 ceramics is performed at nearly 1900°C.

After a 30 minute lag (for the interior of the die to reach the set temperature), the sample was held at temperature for 15 minutes. The system was then cooled to 1700°C at 5-10°C/min. (to avoid cracking), and finally cooled to room temperature by shutting off the furnace.
This tube furnace has a max. working temperature up to 1700ºC. STATF-1700-60-II dual zones tube furnace is real high temperature furnace with up to 1700°C with for max energy saving. It is an ideal tool for preparing new generation material in research laboratory, materials annealing and sintering, composition analysis, quality testing, etc.
2019214In some preferred embodiments, a metal bond abrasive article comprises at least a portion of a rotary dental tool (e.g., a dental drill bit, a dental bur, or a dental polishing tool). Referring now to FIG. 2, an exemplary vitreous bond or metal bond abrasive wheel 200 has arcuate and tortuous cooling channels 220, respectively.
Instead of requiring sintering temperatures of 1,700°C-2,200°C to attain 95% of the porefree density, a few tenths w/o nickel powder added to molybdenum or tungsten powder can activate the sintering process, promoting consolidation to full density at temperatures hundreds of degrees Celsius lower.
