High Temperature Round Ceramic Spacer Standoff Threaded withstand High Voltage
Tag Key words : Round Ceramic Spacer Standoff
Round Ceramic Spacer Standoff Ideal for very high temperature conditions. Exceptional strength in compression and tension. Withstands very high voltage without flashover.
Round Ceramic Spacer Standoff electrically help to isolate components from one another. For instance, you can isolate one sample holder from another sample holder . Available in standard screw sizes. Made from 99.7%+ Al2O3(alumina), these non-porous washers are fully vacuum compatible and bakable to over 400oC.

Alumina is the more common name of Aluminium Oxide and is a hard
wearing material used for many applications. Once fired and
sintered, it can only be machined using diamond-grinding methods.
Round Ceramic Spacer Standoff is an electrical insulator but has relatively high thermal conductivity (35 W/m K). In its most commonly occurring crystalline form, called corundum or a-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.
Aluminium oxide is responsible for metallic aluminium's resistance
to weathering. Metallic aluminium is very reactive with atmospheric
oxygen, and a thin passivation layer of alumina quickly forms on
any exposed aluminium surface. This layer protects the metal from
further oxidation. The thickness and properties of this oxide layer
can be enhanced using a process called anodising. A number of
alloys, such as aluminium bronzes, exploit this property by
including a proportion of aluminium in the alloy to enhance
corrosion resistance. The alumina generated by anodising is
typically amorphous, but discharge assisted oxidation processes
such as plasma electrolytic oxidation result in a significant
proportion of crystalline alumina in the coating, enhancing its
hardness.
Alumina's combination of hardness, high temperature operation and
good electrical insulation makes it useful for a wide range of
applications. Alumina is the most commonly used type of ceramic and
is available in purities up to 99.99%.

Applications of Alumina Components :
High Temperature and Aggressive Environments
Its high free energy of formation makes alumina chemically stable and refractory, and hence it finds uses in containment of aggressive and high temperature environments.

Wear and Corrosion Resistance
The high hardness of alumina imparts wear and abrasion resistance and hence it is used in diverse applications such as wear resistant linings for pipes and vessels, pump and faucet seals, thread and wire guides etc.

Metal Cutting Tools
The high “hot” hardness of alumina have led to applications as tool tips for metal cutting (though in this instance alumina matrix composites with even higher properties are more common) and abrasives.

Microwave Components
The high dielectric constant coupled with low dielectric loss particularly at high frequencies leads to a number of microwave applications including windows for high power devices and waveguides.

Electrical Insulation
The high volume resistivity and dielectric strength make alumina an excellent electrical insulator which leads to applications in electronics as substrates and connectors, and in lower duty applications such as insulators for automotive spark plugs
