Molybdenum Tungsten Tantalum Special Shape Evaporation Boat

Introduction

Tungsten evaporation boat, also known as evaporated tungsten boat or coated tungsten boat, is a device used in vacuum coating and sintering furnace industries. It is made by high-temperature stamping of tungsten sheet and comes in various specifications and shapes. Tungsten boats are typically employed in evaporation processes, where they hold low melting point metals that are vaporized and deposited onto surfaces when heated to around 2000 degrees Celsius. They are also used in ship industries to create metal parts by sintering tungsten metal and connecting its ends with wires.

Application

Evaporation boat sources are important components used in thermal evaporation systems to facilitate the deposition of metals, alloys and various materials. The boats come in different thicknesses and are made from tungsten, tantalum and molybdenum, ensuring compatibility with a wide variety of power sources. Their importance lies in their key role in vacuum evaporation and thin film deposition processes, including the widely adopted electron beam fabrication technique. These multi-functional tools have a wide range of applications in industries such as vacuum coating, electronics, solar energy and metallurgy. To prevent cracking, the container must be heated gradually. Therefore, evaporation boats have become an indispensable part in material analysis and thin film deposition, making a significant contribution to scientific and technological progress.
