High temperature bottom loading furnace for sintering zirconia
In advanced ceramic manufacturing, precise and uniform heating is critical for sintering dental crowns and frameworks made from materials like zirconia. Traditional heating methods can often result in non-uniform heating, leading to suboptimal material properties and color inconsistencies.
Uniform heating with an electrically operated elevator hearth
The Carbolite Gero High Temperature Bottom Loading Furnace (BLF) is designed for high-performance ceramic sintering, such as zirconia dental crowns. The system uses an electrically operated elevator hearth, lifting the load into a chamber with heating elements on all six side walls. This results in uniform heating and helps prevent discoloration. The BLF 1600 °C model utilizes silicon carbide heating elements, while the 1700 °C and 1800 °C models employ molybdenum disilicide elements. Rapid heating and cooling cycles are facilitated by the hearth’s vertical movement. The furnace includes programmable EPC3016P1 controllers and offers excellent temperature uniformity owing to its hexagonal chamber design. Optional features include various digital controllers, data loggers, and custom modifications like a radiation shutter or rotating hearth. Carbolite Gero ensures optimal performance with capacities ranging from 3 to 21 liters, ideal for sintering, glass melting, and operations under modified atmospheres.
