Name :Highly oriented pyrolytic graphite Grade B


Product Overview

HOPG, full name Highly Oriented Pyrolytic Graphite (highly oriented Pyrolytic graphite), is a graphite material with special crystal structure and physical properties. It is prepared by high temperature pyrolysis of hydrocarbon gases (such as methane, acetylene, etc.) deposited on a graphite substrate under specific conditions. Due to the highly ordered arrangement of carbon atoms along the direction of graphite crystal structure during deposition, HOPG has extremely high crystal orientation and a perfect layered structure. HOPG is widely used in scientific research and technology application. For example, in physics research, HOPG is often used as a substrate for the preparation of graphene and other two-dimensional materials; In electronic devices, HOPG's high electrical and thermal conductivity makes it an ideal material for the preparation of high-performance electronic components. In the field of chemistry, HOPG has unique advantages in catalysis and adsorption due to its chemical stability and layered structure. In addition, HOPG is also widely used in thermal management, mechanical components, aerospace and other fields.

Product Features

Highly oriented: The carbon atoms are closely arranged in the form of a hexagonal grid within the layers, and the layers interact with each other through weaker van der Waals forces to form a layered structure. This highly oriented structure makes HOPG exhibit a high degree of anisotropy in physical properties.

Perfect layered structure: Due to the weak interaction between layers, HOPG's layered structure can be easily stripped into single or multi-layer graphene sheets. This makes HOPG one of the important raw materials for the preparation of high-quality graphene.

Excellent electrical and thermal conductivity: Since carbon atoms are covalent bonded in the layer to form a stable hexagonal grid structure, HOPG has excellent electrical and thermal conductivity in the direction of the layer. This property makes HOPG has a wide application prospect in electronic devices, thermal management and other fields.

High mechanical strength: HOPG's layered structure gives it high mechanical strength. Although the interaction between the layers is weak, the covalent bond between the carbon atoms within the layers allows the HOPG to maintain the stability of the structure when subjected to external forces.


Application Fields

X-ray monochromator: It can eliminate the high background intensity caused by white light, fluorescence and stray light in the X-ray tube, improve the sensitivity and accuracy of the instrument, and is an essential part of the X-ray diffractometer.

Neutron filter and monochromator: The filter effect of the neutron stream from the nuclear reactor is better than that of polycrystalline beryllium and quartz crystals, and can be used as a neutron monochromator and analyzer.

Research on basic properties of graphite: Because of its large size and high purity, it can be used to study some basic properties of graphite.

Large-size graphite interlayer compounds: can be used for the basic study of large-size graphite interlayer compounds.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Quick and pretty privacy screen
Color: Beige, Size: 4 Panel-67”
Relatively easy to assemble. Looks very nice at the nursing home of my friend and is sturdy. Unfortunately, aides place towels and sometimes clothes over it and it stands stable. The bamboo color is nice to look at. It is lightweight and can be moved easily!

Good height, versatile.
Color: Brown, Size: 4 Panel-67”
Well made, nice style. Best indoors since it tends to blow over if outside.

Esthetically sound, materially flimsy
Color: Beige, Size: 4 Panel-67”
The item at first seemed okay and quality was good. But it’s a little flimsy and tips over frequently. I’m thinking of returning and replacing pretty soon.
