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.

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.
