Maxthal® 312 (Ti3SiC2) ceramic engineering material is a very inert material with very good corrosion resistance in both alkali and acidic environments. The material's low thermal expansion coefficient together with very high resistance to thermal shock makes Maxthal® 312 a suitable high-temperature engineering material. The service temperature for Maxthal® 312 is:

  • Air: up to 900–1000°C (1650–1830°F)
  • Vacuum or hydrogen atmosphere: up to 1600°C (2910°F)

Maxthal® 312 shows excellent resistance in contact with molten metals. For example, it has been tested with molten lead (Pb) up to 1000°C (1830°F) for prolonged times in next-generation nuclear reactor heat-exchangers.

Maxthal® 312 also shows limited corrosion and erosion in contact with
molten aluminium (Al).

Application example

Electrical contacts

Thin films deposited from Maxthal® 312 targets can be used in both high and low current applications to replace expensive metallic coatings. Electrical contacts from Maxthal® shows a preferable ductile behaviour, possess non-welding properties, shock resistance, chemical inertness, low contact resistance and good high temperature properties. All desired properties in electrical contact arrangements.
