Material efficiency is the main focus of environmental technology. This is particularly important from an entrepreneurial point of view when material prices are rising [Nel17]. The materials therefore demand favorable properties in areas such as service life, processing properties and recyclability [Bie14]. New methods, such as nanotechnology, can be used to produce materials and surfaces with increasingly better properties so that material output decreases [Umw09].
IKH PRODUCTS USED FOR THIS INDUSTRY
Silicon Nitride (Si3N4)
Silicon nitride is a light gray to black ceramic, which is used in high-temperature technology in particular because of its good mechanical properties up to 1800°C. Silicon nitride ceramics are characterized by a low density, high fracture toughness, low coefficient of friction and very good thermal shock resistance.
Silicon Carbide (SiC)
The annual production of silicon carbide (SiC) exceeds 800,000 t, making it by far the most used non-oxide ceramic. In the past it has been used almost exclusively as an abrasive material, which still accounts for a major part of its usage. The development of new processes for the production of dense components with favourable mechanical properties enabled new fields of application.
