Laboratory ceramics

laboratory_crucible
In technological and scientific laboratories ceramic materials are usually used as containers and tools with an extremely high chemical, mechanical and thermal resistance. Typical products are mortars for pulverizing and homogenizing samples or melting pots and boats for drying, sintering or melting-on of substances. In this process, the materials have to remain as inert as possible and must not react with the substances or contaminate these. Moreover, they have to withstand high temperatures and cope with frequent temperature changes without damage. Depending on the specific application, they also have to resist acids and bases of even the highest concentrations or solvents.

Usually, oxide-ceramic materials, such as aluminium oxide, mullite, corundum, magnesium oxide and zircon oxide are used. The typical properties of these materials correspond to the requirement profile described very well:

  • High dimensional accuracy
  • Chemical resistance
  • High temperature stability
  • Very good thermal fatigue resistance
  • High operational reliability and economic efficiency
