Thermal Insulation Advanced Structural Ceramics In Aerospace

Thermal Insulation Advanced Structural Ceramics in Aerospace are increasingly being used in military aircraft, and have been used in the space shuttle and its equipment for many years. Ceramic applications include thermal protection systems in rocket exhaust cones, insulating tiles for the space shuttle, engine components, and ceramic coatings that are embedded into the windshield glass of many airplanes. These coatings are transparent and conduct electricity for keeping the glass clear from fog and ice.

Advanced Structure Ceramics are used as heat shields for fire protection and thermal insulation in aircraft and space shuttles because they resist heat, are lightweight and do not corrode. Other significant characteristics include high melting temperatures, resiliency, tensile strength and chemical inertness.

Advanced structural Ceramics has excellent high temperature strength, excellent fracture toughness, high hardness and unique tribological properties. Silicon nitride aerospace applications result in superior mechanical reliability and wear resistance allowing components to be used under minimal lubrication without wear. These include jet engine igniters, bearings, bushings, and other wear components.

Making Space Travel Possible
Advanced ceramics are playing a critical role in the development of highly-efficient and cost-effective new technologies for space travel. Morgan Technical Ceramics’ division in Erlangen, Germany has been working with a European space development program for a number of years to support its research of ion propulsion systems. A lightweight alternative to traditional chemical propulsion, ion engines have the potential to push spacecraft up to ten times faster with the same fuel consumption, thereby significantly decreasing vehicle size and increasing travel distance.

Mingrui Ceramic Technology which uses electricity to charge heavy gas atoms that accelerate from the spacecraft at high velocity and push it forwards, traditionally incorporated quartz discharge vessels. Quartz has now been replaced by a ceramic oxide called alumina because of the need for a material with the same dielectric properties but with higher structural stability. Alumina is easier to fabricate and offers good thermal shock resistance, ensuring that the chamber can withstand the extremes of temperature that occur during plasma ignition. It is also lighter, which reduces the costs associated with each launch.

Ceramics are used to achieve heat resistance. The heat-insulating properties of ceramics have been known for centuries, and the materials are used for thermal control in everything from batteries, magnets, and semiconductors to insulating tiles within aircraft. Ceramics have been adopted for multiple applications the design of space vehicles, including thermal protection from the exterior exhaust and interior protection in the form of insulation.

Unique Properties, Specialized Materials

Whether Mingrui custom ceramic parts are used in our atmosphere, in outer orbit, or beyond, extreme conditions exist that are overcome by the unique properties only ceramics deliver, including:

1. Electrical Insulation – isolating critical wires and components from damage
2. Thermal Insulation – resistance to high temperatures
3. Durability – resistance to repeated and extreme thermal cycling and friction
4. Corrosion Resistant, Chemically Inert – no contamination of sensitive instruments
5. Strength to Density Ratios – comparable to the most novel engineering alloys
