PHI Carbon Heater Graphite Insulation PHI Carbon Heater Graphite Insulation (Temp up to 2000 ํc) We supply high quality carbon graphite heater, vacuum furnace spare parts, and
Carbon Graphite Bearings Bushings Helwig Carbon Products has been manufacturing carbon graphite bushings and bearings for over 40 years. Self lubricating carbon graphite bushings are ideal for applications where normal lubricants can not be used.
To achieve the highest temperatures, AVS manufactures graphite furnace, using graphite heater elements and felt or rigid graphite board insulation materials. When a graphite furnace presents a risk of carbon reaction or particulate contamination with the customer's product, AVS can provide refractory metal hot zones.

Graphite is known to excel in extreme conditions, withstanding heat, pressure and aggresive chemicals. It is especially noted for dimensional stability in high temperatures and pressure fluctuations.
In particular, our high-purity graphite materials, which contain less than 3 ppm of ash, are widely used in heaters and crucibles for pulling single crystal silicon and boats for liquid-phase epitaxial growth in the semiconductor manufacturing processes.
Pictured to the left are graphite foams that have been SB metalized then bonded between two aluminum plates to make a graphite foam cored heat spreader. The figures to the left show the cross section of (top) graphite carbon and (bottom) graphite foam (cell webs).
Artists' graphite-coated paper is used like carbon paper to transfer-trace a design to another surface. Greaseless, clean to work with. Box of 12, 18 x 24 sheets on roll.
Pyrogenics Mission Provide engineered carbon based products for key industries requiring innovative material solutions. Largest single source producer of pyrolytic graphite, thin films, and specialty carbon
The ultra high heat treatment temperature is required to drive the solid/solid, amorphous carbon-to-graphite phase transformation. The morphology of most synthetic graphite varies from flakey in fine powders to irregular grains and needles in coarser products.
MIT's spongy graphite-carbon solar steam machine — diagram on the left, in action on the right When sunlight hits the graphite, hot spots are created that draw water up through the carbon foam
CARBON-GRAPHITE MATERIALS FOR HIGH-ENERGY BRAKES Robert C. Bill Lewis Research Center FRICTION AND WEAR OF CARBON-GRAPHITE MATERIALS FOR HIGH- ENERGY BRAKES 7. Author(s) Robert C. Bill 9. Performing Organization Name and Address of the brake system (lining and heat-sink material) of carbon graphite. Carbon-graphite
In furnaces, carbon and graphite felts are used for insulation purpose, as they offer low thermal conductivity, low specific heat, and permits rapid heating and cooling of the furnace.
This work originated from a need for understanding heat transfer in carbon-fiber/epoxy natural-gas tanks undergoing rapid heating during refilling. The dissertation is focused on the determination of the anisotropic thermal properties of carbon-fiber/epoxy composite
PBM's Carbon/Graphite Seated Valves have successfully passed a 10,000-cycle hot oil test at 650F, demonstrating the valve's suitability for use with hot liquids, including heat transfer oils. Carbon/Graphite Seated Valves are designed for use in applications such as
Blanket products can subsequently be covered by a graphite paint and board product can be supplied with a hot face covering of graphite foil or foil-bonded carbon composite. These improve reflectivity (i.e., reduced emissivity) of the heat from the graphite heaters back toward the load as well as protect the surface from damage by process or
expansion coefficient of graphite and other materials. The thermal expansion figures for carbon and graphite are considerably lower than those for metals.
Elemental Forms of Carbon Graphite, Diamond, Coke, and Carbon Black Carbon occurs as a variety of allotropes. There are two crystalline forms diamond and graphite and a number of amorphous (noncrystalline) forms, such as charcoal, coke, and carbon black.
Carbon in the form of crystalline graphite possesses a combination of properties including lubricity, refractoriness, chemical inertness, as well as thermal and electrical conductivity.
