Name :Highly oriented pyrolytic graphite Grade C


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.

Soap bar tumeric
This was the best soap ever. Did not turn my skin orange, (which I was little afraid of) and left it feeling nourished. Used in the shower as a body soap and can't recommend it enough.

I loved it
The texture is amazing, too expensive for its size and it doesn’t last.

So far so good after 3 washes
A noticeable difference after washing my face just 3 times so far with the soap. My face felt softer and smoother. It's not harsh, doesn't dry out my face, or leave soap residue. I will definitely continue to use it.

Great product
I love the soap! Used daily and it lasted a little over a month. A little pricey, but it was worth every cent! It leave great moisture!

Different from the Seller's pictures, but it's a pretty good bar of soap for the price!
DISCLAIMER: the pictures that I have added here are 1 week after using the soap, and I kept the soap in the box on my tub until it got too wet and I threw out the box... then decided to keep the box to take pics and do a review. This soap is 5oz and a nice chunk of soap for the price! It's about the same size of the box, but the picture and brand that the seller has of the soap is different from what I received.... a dark red/orange soap from Natrulo truly natural? It actually has been working fine for me and my daughter, but I would love to try the same soap and brand that I paid for as advertised by Amazon (which is why I gave this 3 stars... if it was the same soap and brand I would give it 4 since I just started using it). I'll contact the seller to see if I can get the same soap and then do another review. Thanks!
