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.

Exactly what I needed
These are solid and work really well. They’ve held up perfectly and as long as I don’t lose them I can’t imagine them wearing out for a really long time.

Step up your fresh breath game!
This!!! This is the step I was missing in my oral care routine. I was previously using one of those cheap plastic little scrubbers you get from the dollar store to brush my tongue but didn't feel like it did much, it was just a routine. A friend of mine suggested a metal tongue scraper and said it was really helping to keep her mouth clean and fresh after a bunch of expensive dental work. Well, shoot....why not? I won't pretend like I know all the scientific benefits behind tongue scraping, but all I know is from the first time, I was sold on it. You simply hold both ends in your hands and gently place the curved groove on the back of your tongue towards your throat, scraping gently down towards the tip of your tongue. You'll be shocked at the amount of goo that comes off! At least I was, and I am a daily tongue brusher! Rinse the muck off between each scraping and your tongue will be clean and neat. 2 points of caution: 1) Be careful going too far back at first. It can trigger your gag reflex so only go back as far as you feel comfortable and work your way back. 2) You have really sensitive large taste buds at the base of your tongue, so do not press and drag too hard. You can use a small amount of pressure, but not too much is needed. You can definitely hurt your tongue that way (I did, and it was not nice). I've noticed that my breath is much fresher for much longer on days when I scrape my tongue with this. (I did a control test with my old plastic brush and this steel scraper, and the steel scraper outperformed by a mile). My mouth felt cleaner and I don't know if this can be proven, but I feel like food tasted better? My morning coffee seemed even more enjoyable after my first round of tongue-scraping. You get two for such a good price and it will last such a long time. Get one for you and your SO. To be honest, all the brushing and flossing, and mouthwash in the world doesn't replace scraping all that gunk off your tongue if you want fresh clean breath. I highly recommend it.
