Actually, there are many depending on the particular application requirements (i.e. circuit board, laid piping, etc.) and actual temperature tolerances, the material can be:
* Concrete
* Certain types of plastics
* Ceramics
* Polyurethane foam (often in combination with other materials)
* Natural rock or mineral
* Glass wool & fiberglass
* Calcium silicate
* Water
One of the materials used to shield against some of the highest temperatures are the 24,000 six- by six-inch blocks on the Space Shuttle hull that are used for atmospheric re-entry. The tiles are made out of silica fibers, which are produced from high-grade sand!
It turns out that silica is an excellent insulator because it transports heat very slowly. When the outer portion of a tile gets hot, the heat takes a long time to work its way down through the rest of the tile to the shuttle's more fragile skin. The tiles keep the orbiter's aluminum skin at 350 degrees or less.
In integrated circuits, lead, copper, gold, silver or other materials may be used to help distribute the heat or radiate it away from the integrated circuit to prevent overheating.
Asbestos also works but is largely no longer used due to health risks (mesothelioma).
New "nanocrystals technology" also known as "quantum dots," are used for better transmission of electrical energy versus heat transference.

Is heat strengthened the same as annealed?
No. Heat annealing is used to reduce stress in a material such as steel of glass. Strengthening is caused by several factors such as crystal alignment or carbon precipitation.
What material to be used to separate heat from cold?
An insulator is the name of this substance.
How can you save thermal energy?
There is no way to save thermal energy in the long term; heat tends to escape. You can reduce the losses by some isolation measures, as those used in a thermos bottle.There is no way to save thermal energy in the long term; heat tends to escape.

What is an insulator of heat?
Heat insulators are simply materials that don't allow heat to pass through it. Some examples of these materials are woods, glass and ceramic. Ceramics are the most commonly used thermal (heat) insulators. Examples include the tiles that form the heat shield on the Space Shuttle.
How did people heat water before electricity?
They used fire that is basically caused by friction. electricity is used now a days to save fuel and reduce pollution but it is not the only solution.
What is the heat of electricity?
Amount of electrical energy converted to heat energy when current flows through a conducting material.According to Joule's Law, quantity of heat energy dissipated is given by,Q=i2Rtnotein power transmission, aluminum wires* are used to reduce the heat energy lossusing a step up transformer,we increase the voltage and reduced in current to reduce heat loss.(heat loss is proportional to the square of current.)* though silver is the material with minimum resistance,it is too dear to be used as transmission wires.

No. Heat annealing is used to reduce stress in a material such as steel of glass. Strengthening is caused by several factors such as crystal alignment or carbon precipitation.
What is damping material used for in ultrasound?
Is a material used to reduce the mechanical vibration of ultrasounds.
What is the major material used in constructing transmission lines?
The major material used in the construction of transmission lines is aluminum alloy. Steel is also used to reinforce the lines. No insulation is used for overhead transmission lines.
What is cavity wall?
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. By doing this the porous material absorbs the escaping water and air.
What is the difference between phenolic piston and steel piston?
Phenolic is a composite material and is used to reduce the transfer of heat from the brake pads to the brake fluid via the piston.
What is used to reduce the effects of attenuation for a digital transmission signal?
repeater
What material is used with endodontic spots?
Heat curing
Is there an antibiotic that can be administered prior to birth to reduce the risk of hpv transmission to the infant?
No, there is no antibiotic used to reduce the risk of HPV transmission. Talk with your healthcare provider about your concerns, as they are likely unfounded.
What are cavity walls?
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. By doing this the porous material absorbs all of the air and water and stops it from escaping the house or building.
Is a styrofoam a good conducter of heat or a bad conductor of heat?
It is a bad conductor of heat, that is why it is used as an insulating material.
Which material is used to produce heat in an electric iron?
tungston
