Laboratory furnaces and ovens are essential tools for various processes across different scientific and industrial fields. Here are some common processes you can perform using a laboratory furnace or oven:
Processes Using HOBERSAL Laboratory Furnaces
- Annealing:
- Purpose: To reduce hardness, relieve internal stresses, and improve ductility and toughness.
- Application: Metals, glass, and polymers.
- Calcination:
- Purpose: To induce thermal decomposition, phase transition, or removal of a volatile fraction.
- Application: Minerals and other solid materials.
- Ashing:
- Purpose: To remove organic material by heating samples to high temperatures in the presence of air or oxygen.
- Application: Determination of inorganic content in materials.
- Sintering:
- Purpose: To compact and form solid materials by heat without melting to the point of liquefaction.
- Application: Ceramics, metals, and plastics.
- Heat Treatment:
- Purpose: To alter the physical and sometimes chemical properties of a material.
- Application: Metals and alloys.
- Crucible Melting:
- Purpose: To melt small amounts of metal or glass.
- Application: Small-scale metal casting, alloy creation, and glass working.
Processes Using HOBERSAL Laboratory Ovens
- Drying:
- Purpose: To remove moisture from samples.
