L&L Special Furnace Co. Inc. shipped an electric box furnace to a U.S. manufacturer of calcium-phosphate materials used for medical devices. The calcium-phosphate powder is sintered in the furnace at a temperature of approximately 2200°F (1204°C). It is held at temperature for four to eight hours. The top layer is removed after processing, leaving pure calcium-phosphate powder. The powder is then mixed with proprietary materials and made into slurry that can be applied to various appliances deployed in the medical field.
The furnace, which has an effective work zone of 10 inches high x 15 inches across x 13 inches deep, is designed to be placed on a benchtop or an optional stand. It has a control that has six individual programs with up to six segments each. The furnace can also be equipped with over-temperature protection.
The calcium products are known as orthophosphates and contain a variety of chemical structures deployed in the medical and dental field. In slurry form, the calcium phosphate can be used on various items for medical applications with very low inflammation rates and direct bonding to soft bone and tissue. It is used in a variety of applications including dental implants, bone implants and other medical procedures.
