201858A frequently asked question is, "How can I keep my vacuum furnace performing like it was when it was brand new?" This goes hand in hand with the question "How should I operate and maintain my vacuum furnace to maximize my investment and produce repeatable high-quality results?"
Because the sintering temperature does not have to reach the melting point of the material, sintering is often chosen as the shaping process for materials with extremely high melting points such as tungsten and molybdenum. The study of sintering in metallurgy powder-related processes is known as powder metallurgy. An example of sintering can be
Vacuum, Vol. III No a high temperature RESISTANCE-HEATED HIGH VACUUM FURNACE W. J. Kramers M.A., D.Phil., F.R.I.C. & F. Dennard. Summary MOST OF THE TECHNICAL FURNACES used for heating objects of reasonable size to high temperatures under very high vacuum are at present heated by high frequency induction, though the equipment is expensive and often difficult to obtain.
1. It is used for isostatic pressing of sintered materials under high pressure gas and high temperature. 2. The hot isostatic pressing device is mainly composed of a pressure vessel, a gas pressurizing device, a heating furnace and a control system.

VACUUM EVAPORATION SOURCES - view catalog sheet (PDF) The AL2O3 coated evaporation basket was first introduced by CM in 1957. Since that time these evaporator baskets have proven to be vital to the vacuum metallizing industry. The parts consist of either tungsten or molybdenum wire formed into baskets and set at 1500O C in hydrogen atmosphere.

2019111The furnace used for these processes has special requirements for internal structural materials, including high-temperature resistance and high purity and low vapor pressure. Refractory metals (molybdenum, tungsten, and niobium) are suitable for high-temperature furnace components, the main applications of which are as follows.
