Electrical Insulation Colored Zirconia Ceramic Parts for Optical
Jig Products
Key words : ceramic parts for optical
Mingrui Ceramic proposes applying forsterite (especially developed
for optical products), steatite, and alumina ceramics to optical
products, because these ceramics satisfy requirements such as light
blocking effect, junction with glass, adequate thermal expansion
coefficient for glass and other peripheral equipment, heat
conductivity, specific heat, and electrical insulation. We can also
supply colored zirconia and white zirconia for optical jigs.
ceramic parts for optical 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.
ceramic parts for optical 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.
ceramic parts for optical 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.

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.

Ceramic Components for aviation aerospace
ceramic parts for optical 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.
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:
Mingrui offers ceramic material formulations in both aluminum oxide (Al2O3, alumina) and zirconium oxide (ZrO2, zirconia) as well as specialized, customer defined material including: SiC, B4C and quartz, satisfying virtually any custom ceramic parts application for the
aviation and aerospace industries. Our rigorous quality assurance program and going the extra mile, means that whether in the air or in
space, the custom ceramic parts we manufacture will do the same for
our customers.
