Duratight graphite crucible is made of fine raw
material and added anti-oxidation elements, having
properties such as:
1. thermal stability: according to the heat shock
working condition of graphite crucible, we make
special design s to guarantee the quality of
product.
2. erosion resisting: uniform and close basal body
design delays the erodibility of the crucible.
3. dent resistance: Duratight graphite cucible can
endure very strong heat impact strength, so any
fabrication processing can be practised on it.
4. acid resistance: special material added improve
the quality of crucible dramatically, make the
crucible have good acid resistance property, and
extend the working life of the graphite crucible
greatly.
5. fine thermal conductivity: high content of fixed
cabon ensures good thermal conductivity of graphite
crucible, shorten the dissolve time of liquor metal
and reduce the consumption of oil and other energy
obviously.
6. control of metallic pollution: strict control of
crucible material assures that there is no pollution
to the matal during dissolving.
7. quality stability: high-pressure forming technics
and quality assurance system can guarantee the
quality stability of graphite crucible better.
Welcome to offer your samples and drawings, and
inform us the working condition of the crucibles you
need, we will choose suitable material for you and
provide you with satisfactory
  product and
service.
