Sintering also causes zirconia to shrink approximately 25%. While zirconia transforms from one structure to another at around 1,100°C to 1,200°C, most sintering furnaces fire at temperatures closer to 1,500°C. Final sintering temperatures can have a profound effect on the zirconia.
Dental Sintering Furnaces. Dental sintering furnaces are used to process dental zirconia after it has been milled into a crown, bridge, framework or other restoration. These furnaces are capable of reaching the extremely high temperatures required to sinter zirconia to its final hardness.
Alibaba.com offers 708 dental crown sintering furnace products. About 65% of these are laboratory heating equipments, 9% are dental consumables, and 1% are industrial furnace. A wide variety of dental crown sintering furnace options are available to you, such as heat treatment furnace, sintering furnace.
The zirconia sintering furnace adopts the 1800℃ pure heating rod, which does not cause secondary pollution to the dental crown; the furnace adopts four-sided heating, which is more uniform than the traditional muffle furnace and crystallization furnace. The dental crown of the fired crown has better consistency.
The CDF dental furnace is equipped with 3 robust high-quality heating elements made of silicon carbide. In contrast to many molybdenum disilicide heating elements these are free of any chemical interaction with zirconium oxide. The dental crowns and frameworks are placed in sintering trays which are filled with a bed of zirconium support beads.
Metal porcelain teeth soft alloy sintering furnace zirconia sintering furnace is mainly used for crystallization and sintering of zirconia crowns in denture processing factory. The specific design in combination with sintering beads provides for good sintering results in a nearly oxygen-free atmosphere at very low argon consumption.

Mar 30, 2013 · Zirconia sintering furnace. and they are terrible for Dental Zirconia. IMO The metal types may be the same, but the metal purity, the gauge and the tip make a
The multi-function sintering furnace is mainly used for the sintering of zirconia dental crowns and soft metal dental crowns. It can combine the sintering of two materials in one furnace, and effectively improve the customer's working efficiency and save the customer's production cost.
Sep 09, 2015 · Sintering furnaces therefor on the market are for the most part convection types, very similar to porcelain ovens, as it produces more esthetic results. Question: Does the Yttria content alter the zirconia's time to sinter or high sintering temperature? Answer: Yttria is a stabalizer as zirconia by itself is an unstable element.
