  • What Are Refractory Metals?
    Refractory metals are different. As a group they provide a number of unique characteristics - such as resistance to high heat, corrosion and wear - making them useful in a multitude of applications. The next time you climb into your automobile take note that you are surrounded by components which

Liner replacement for the. 68-inch inside diameter and 36-inch deep crucibles. was particularly expensive. Figure 1. SOLUTION. ACME designed
  • Mullite (3Al2O3-2Si02 or Al6Si2O13)
    usually has an off-white or tan color. Depending on the purity and density, mullite can have superior dielectric and thermal shock properties and resistance to slag and silicate refractory bonds. Mullite is used for refractory tubes, industrial crucibles, analytical labware, dielectric substrates
  • Carbon
    a protective coating must be used in reducing or vacuum atmospheres to prevent oxidation at elevated temperatures. Depending on the purity, density and crystal structure carbon is used for refractory linings, industrial crucibles, arc furnace electrodes, analytical labware, composites, refractory cements
  • Zirconia Toughened Alumina (ZTA)
    and density, zirconia toughened alumina is used for refractory tubes, industrial crucibles, analytical labware, wear components, refractory cements and abrasives.
  • Alumina
    versatility and relatively low cost. Depending on its purity and density, alumina is used to make refractory tubes, industrial crucibles, analytical labware, dielectric substrates, wear components, refractory cements, and abrasives. Alumina's main drawback that it has relatively poor thermal shock
  • Boron Nitride
    . Depending on the purity, density and crystal structure, boron nitride is used for refractory linings, industrial crucibles, arc furnace electrodes, analytical labware, composites, refractory cements and super abrasives. Hexagonal BN is structurally weak and used as a high temperature lubricant
  • Zirconia (ZrO2)
    on the purity and density zirconia is used for refractory tubes, industrial crucibles, analytical labware, sensors, wear components, refractory cements, thermocouple protection tubes, furnace muffles, liners and high temperature heating element supports.
