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.

Great toy for a smaller dog
Color: Checkers - Dinos Bruto (Purple), Size: Mini
This is a small, firm, sturdy toy designed for chewing. It isn't a soft toy and it does not have a squeaker. My dog is only 8 lbs, and this is a perfect size for her. I discovered these smaller toys through my groomer. Other manufacturers make this size, as well. The "hard chew" part indicates that this toy will not be chewed to death easily. The oldest one that we have is still in good condition. It's a baby duck (also available on Amazon) and it's over a year old. The dinosaur is colorful, easy to throw, and a really cute. Every night, my dog gives these small toys a bath, cleaning them up by licking each one before going to sleep. It's as if they are her babies. Since she never had a liter, my vet said that they are about the size that her babies would have been, so she may see them as her babies. She treats them well. Every now and then they go" swimming" in the washing machine and come out looking bright and new again.

Updated, still going !! didn't last two minutes.
Color: Checkers - Elephant (Gray), Size: Large, Color: Checkers - Elephant (Gray), Size: Large
I hated giving this a 1 star, because it was so cute when I unpacked it today. I just gave it to my dog and in less than two minutes he has a hole ripped in it.! he loves it so I don't wanna take it away from him, but I'm sure it's going to be gone in another few minutes. Why can't someone make a stuffed animal for a dog that lasts like they say so on their listing? I really should take it away from him and send it back, but I don't have the heart. I had to come back and give this a better review. it deserves at least four stars because even though he ripped holes in it, this one has lasted way longer than any other toy. He's actually still playing with it, and it still has some crinkle left to it so he didn't destroy the whole thing as quickly as he did other stuffed animals. I will certainly buy another one because at least it lasted a week so far!

Looks Nice But Destroyed by my Lab
Color: Checkers - Elephant (Gray), Size: Large, Color: Checkers - Elephant (Gray), Size: Large
A really cute little elephant. My lab loved it and carried it around for a week. Then the elephant began losing body parts. Both legs are gone now plus the big squeaker. Lab still likes the elephant and carries it around. Its loosing stuffing and the real question is what body part is next. Its nice but not tough.

Still in one piece and played with!
Color: Checkers - Dinos Bruto (Purple), Size: Mini
Very durable for my little King Charles Chewer. She's had it for a while now and all though the chewing phase has calmed down, she still can be somewhat rough with the toys. The little dino is standing firm. It was a battle she figured she couldn't win with Dino. Now he's a fetch/ tug o war toy that still gets a few nibbles.
