ΖIrconia Silicate Zircon Crucibles For Glass Making Laboratory , Non - Ferrous Metals


Ζirconia Silicate (Zircon) Crucibles for glass making laboratory, non-ferrous metals and alloys, especially Aluminium


Zirconium Silicate ( ZrSiO4) or Zircon has unique and outstanding properties as a refractory material. It has no definite melting point and dissociation into zirconia and silica begins at 1550°C with little physical change apparent until 1700°C. Its favorably low thermal expansion properties and lack of crystalline inversion give it a higher thermal endurance than other ceramic refractory materials.


One of the major uses of Zircon crucibles is in the glass making laboratory. When glassy or siliceous slags are present in your melt ceramics Zircon crucible is the solution. Zircon crucibles are often used for melting platinum-group alloys. Their strength and resistance to high temperature makes them right for those special “dirty refining” applications. Zircon crucibles are also suitable for metal melting and casting since the cast metal does not stick to the crucible even at high temperature. Zircon crucibles performs well with many non-ferrous metals and alloys, especially Aluminium. Zircon is not “wetted” by Aluminium, so is relatively unreactive.

Zirconia Silicate (Zircon) Crucibles Key Features:

  • 1550 C max. service temperature
  • 64% wt. Zirconia and Hafnia, 35% wt. Silica
  • Exceptional thermal shock resistance, suitable for fast thermal cycling
  • Superior performance against molten material
  • Extended life – low cost
  • Low reactivity - excellent chemical resistance to corrosion from chemicals, especially resistant against alkali material
  • Low porosity and exceptionally fine surface finish enhance cleaning from heat treatment residuals and prevents chemical attack
  • High mechanical strength and wear resistance
  • Consistent dimensional control

Applications.

Analytical applications, metals melting, ceramic powders heat treatment, material acid treatment. Zirconia crucibles are ideal for the melting or sintering of precious metals and super-alloys. One of the major uses of Zircon crucibles is in the glass making laboratory. When glassy or siliceous slags are present in your melt t-ceramics Zircon crucible is the solution. Zircon crucibles are often used for melting platinum-group alloys. Their strength and resistance to high temperature makes them right for those special “dirty refining” applications. Zircon crucibles are also suitable for metal melting and casting since the cast metal does not stick to the crucible even at high temperature. Zircon is notable in being unwetted by molten Aluminum.
