Superior Technical Ceramics (STC) introduced a new direct-pressure sintered silicon nitride (Si3N4) powder-to-part component manufacturing process featuring a sinter-HIP furnace. The new furnace can accommodate a range of inert gas atmospheres, including ultrahigh-purity, cryogenically sourced nitrogen, which is a key component of the Si3N4 direct-pressure sintering process. The furnace has an 11-inch-diameter x 22-inch-high graphite hot zone that is fully controlled to temperatures up to 3812°F (2100°C).
CeraMaterials, a supplier of graphite and ceramic products, announced a new subsidiary that will focus on graphite insulation, materials and composites.
Today’s electronic equipment would not exist without the presence of multilayer ceramic capacitors (MLCC). For example, a personal computer utilizes approximately 700 MLCC, a liquid crystal TV has approximately 500 and a car navigation system uses approximately 1,000.
A new chiller-technology-based aluminum nitride (AlN) ceramic heater with an embedded tungsten RTD sensor is capable of heating from 100 to 450°C at 200°C per second and cooling from 450 to 100°C at 100°C per second.
Morgan Crucible combined its two divisions, Morgan Ceramics and Morgan Engineered Materials, to create a unified business under the new name Morgan Advanced Materials.
Alumina ceramics and steatites have primarily
been used in the furnace industry for electrical insulators with advantageous
structural properties at elevated temperatures. Steatites are better heat
insulators but do not have nearly the strength or the suitability for
high-temperature applications that alumina formulations have.
