Graphite parts
Graphite parts are increasingly widely used in vacuum furnaces. They are not only used for heating elements and heat shields for vacuum furnaces, but also for structural parts, such as brackets, trays, guide rails, bolts, bearings, fan blades, etc. The application of graphite in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, stainless steel, etc., reduces costs, improves certain properties of vacuum furnaces, and expands application field of vacuum furnaces.
Graphite is with good vacuum performance, thermal conductivity, low thermal expansion coefficient, increased strength with increasing temperature, good processing technology, etc., coupled with low cost, so it is a high-quality and low-cost material.

Graphite heater
Graphite heater refers to an electric furnace made of graphite material to heat the heating element part. Graphite has excellent electrical and thermal conductivity properties. Graphite is commonly used as a heating element in special industrial furnaces or electric furnaces. In the early stage of industrial electric furnace, graphite electrodes were used as heating elements, and then high-power electrodes with high density were used as heating elements. With the development of the semiconductor industry, heating furnaces for refining materials such as single crystal silicon, single crystal germanium, gallium arsenide, phosphorous and indium, select high-purity fine-structure graphite and isotropic graphite as heating elements.

Graphite crucible
High-purity graphite crucible has good thermal conductivity and high temperature resistance. In high temperature use, the coefficient of thermal expansion is small, and it has a certain resistance to rapid heat and cold. It has strong corrosion resistance to acid and alkali solvents and has good performance. The chemical stability. High-purity graphite crucibles have a wide range of applications, mainly used to smelt various silver, aluminum, lead, copper, zinc and other non-ferrous metals, medium carbon steel and rare metals. The high-purity graphite crucible has stable quality and long service life, greatly reduces fuel consumption, reduces labor intensity, improves labor intensity, and creates better economic benefits.
