Advantages of tungsten boats
The advantages include exceptional heat resistance (t° melting W = 3422°C), high modulus of elasticity and resistance to temperature creep, the minimum coefficient of thermal expansion among metals, corrosion resistance and resistance to aggressive reagents, strength, reliability and durability.
The disadvantage is the high cost of production. Tungsten is a rare metal, it is quite difficult to separate in pure form, it is poorly treatable.
Such boats is made by powder pressing of high-quality tungsten with machined. The method of production and the refractoriness of the material guaranty high heat resistance and operational reliability of the boats. They are made of any parameters and shape. Dimensions and tolerances — as agreed with the customer. The price is determined by size, complexity configuration and additional requirements issued by the employer.
Tungsten boats are used in vacuum technology.

Tungsten boats are widely used in electronics, electrical engineering, ceramic industry in high temperature vacuum furnaces or furnaces with hydrogen atmosphere for recovery of oxides of metals, sintering and annealing of powder products from metals and non-metals, growth of single crystals, melting glass, etc.
