Dental Sintering Furnace
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. The sintering process, which can involve pressure as well as heat, reduces the porosity and increases the density of ceramic materials such as zirconia. During the sintering process zirconia undergoes a significant amount of shrinkage. When choosing a sintering furnace for your practice or lab it is important to consider its capacity, it’s pre-programmed cycles and automation features. With new options for both lab and chairside sintering, producing your own zirconia restorations is faster and easier than ever.

Dental Zirconia Sintering Furnace Process:

The sintering procedure is what gives zirconia restorations their strength. Sintering is a thermal treatment that is widely used to augment a material’s strength and structural integrity.

To obtain sintered zirconia, the heat from the sintering furnace is transferred to the surface of the material and then thermally conducted to the core.

 A heating, sintering, and cooling phase are all part of the sintering process.

How hot does a dental sintering furnace get?

This sintering furnace is used to process dental zirconia at high temperature between 1400°C and 1600°C after milling into crowns, bridges, implant fixtures and other restorations. 

What material is used in sintering?

Some of the materials / powders used in metal sintering includes: Iron and Carbon Steels. Iron-Copper and Copper Steels. Iron-Nickel and Nickel Steels.

What metals are used in sintering?

This technique uses various metals, including aluminum, brass, bronze, and stainless steel. Sintering allows for greater control over the manufacturing process and can result in more consistent products. 

What gases are used in sintering?

The process of sintering with atmospheric pressure requires a protective gas such as hydrogen, nitrogen, or carbon monoxide.

What are the 3 principal sintering processes?

Basically, sintering processes can be divided into three types: solid state sintering, liquid phase sintering and viscous sintering, which are all widely used in the industry. The driving force of sintering is the reduction in the total. An external pressure or force is sometimes applied to accelerate the process.

The 3 Stages of The Sintering Process

  1. Compose The Sintering Powder. This is the stage in which the composition of your metal parts is determined and mixed.
  2. hen packed and pressed into the desired part shape.
  3. Heat Sintering Materials.

Sintering furnaces are in great demand in dental industry; therefore, such furnaces also called dental furnace or dental sintering furnace. In dental, Zirconia is considered most reliable material for crown, bridge, framework or other restorations. This sintering furnace is used to process dental zirconia at high temperature between 1400°C and 1600°C after milling into crowns, bridges, implant fixtures and other restorations. This sintering process requires various temperature ranges and dwell times; therefore, a dental furnace must have automatic and programmable temperature control features. Only with this feature, a best zirconia restoration can be made.
