MolyTec combines intermetallic high purity heating elements made of molybdenum disilicide (MoSi₂) and vacuum-formed insulation made of polycrystalline mullite/alumina wool (PCW) in heating systems ready for installation. The system permits controlled and precise heating at application temperatures up to 1450°C (2642°F). MolyTec is fully compatible with all technically comparable heating systems and can be integrated into oxidation/diffusion and LP CVD furnace systems.

Your benefits with MolyTec:

• Stability at process temperature higher than 1350°C (2462°F)
• Quick and simple installation and exchange
• Controlled and precise heating at application temperatures up to 1450°C (2642°F)
• Long service life compared to common used heating systems with e.g. wire
• Reduction of the process time in terms of higher process temperature compared to wire
• High surface loading: 15.5 W/cm² at 1400°C (2552°F)
• Homogeneous temperature distribution 

MolyCom®-Hyper 1800 are electric heating elements made of the high purity intermetallic compound molybdenum disilicide (MoSi₂) with ceramic additives. Thanks to their unique properties the MoSi₂ elements enable a higher surface loading compared to common used electric heating like e.g. with wire. Thus they can be used for operation temperatures higher than 1350°C (2462°F).

MolyCom®-Hyper 1800 heating elements can be combined with vacuum-formed insulation tubes made of polycrystalline mullite/alumina wool (PCW) to electric heating systems for oxidation/diffusion and LP CVD furnaces. The elements are supplied, also in complex geometries like 360° panorama heating elements.

Your benefits with MolyCom®-Hyper 1800:

• Higher surface loading compared to alternative heating solutions
• Suitable for operation temperatures higher than 1350°C (2462°F) compared to common used electrical heating e.g. wire
• Longer life time of the heating elements
• Available as ready for installation heating system with vacuum-formed insulation tube up to 1450°C (2642°F) operation temperature, called MolyTec

UltraVac insulation materials offer very precise dimensions, surface quality and homogeneity in particular at complex part designs. This way, we implement individual and application-specific unique shapes or small series made of polycrystalline mullite/alumina wool (PCW) for diffusion and CVD furnaces up to 1450°C (2642°F) operation temperature.

The structure of the vacuum-formed insulation shapes remains stable even at high temperature. Thanks to the very good thermal shock behaviour, UltraVac is suitable for use in high-temperature furnaces with rapid temperature gradients.

Your benefits with UltraVac:

• For diffusion and CVD furnace up to 1450°C (2642°F) operation temperature
• Shapes ready for installation available as vestibule blocks or insulation tubes as single parts or small series
• Complex design possible
• Very good thermal shock behaviour
• Stable structure at high temperatures
• Longer life time compared to common used vacuum formed insulation parts
