Molybdenum has excellent properties: high melting point, high creep resistance and low thermal expansion. By adding other metals to generate molybdenum alloys, these properties are significantly enhanced. According to the user's application environment and operating temperature, TLWM can provide users with suitable pure molybdenum or molybdenum alloys.
In the absence of oxygen, molybdenum has excellent corrosion resistance to various acids, metal liquids and molten glass. Within 1100°C, molybdenum is relatively stable in hydrogen, ammonia and nitrogen. Mainly used in metallurgical industry, mechanical processing, glass ceramic industry container. Such as high melting point metal sintering molding, fused quartz glass, etc. The molybdenum crucible made by pressing with isostatic press and then sintered in an intermediate frequency furnace is turned and milled. The diameter of the molybdenum crucible can reach Φ600mm, the height can reach 500mm, and the wall thickness ranges from 0.2-15mm.
product quality
The purity of the tungsten boats and molybdenum boats produced by our company is above 99.95%. The process standards and strict quality control greatly increase the service life of the products in the later use.
Product packaging
Our company uses wooden boxes for outer packaging. Tungsten boats and molybdenum boats are all wrapped with moisture-proof paper, and the box is filled with foam plastic to avoid problems during transportation. Using imported materials, independent production, materials and dimensions can be customized according to customer product requirements! It has the advantages of stable quality, long life, etc., and is well received by users at home and abroad.
Classification of evaporation boats
Flat trough boat
Suitable for materials with high wettability
V-shaped tank boat
Suitable for materials with less wettability
Oval trough
Suitable for materials in molten state
Spherical tank boat
Suitable for expensive materials such as gold and silver
Narrow tank boat
This design prevents the evaporation material from sticking to the filament clamp
Steam aluminum boat
A layer of alumina is plated on the surface of the boat body to help evaporate the boat’s corrosion-resistant molten materials
Evaporation boat customization
The choice of evaporation boat (molybdenum boat/tungsten boat) determines the quality of the coating. We use professional customized materials, independent production, research and development and design, materials and sizes can be customized according to customer product needs! It has the advantages of stable quality, fast response time, good electrical conductivity, and strong sealing and permeability.
