The Physical Basis and Applications of Nanodiamonds

Diamond is the hardest material on Earth and one of the most valuable. Among all natural and synthetic materials, diamond possesses the highest hardness and thermal conductivity, the broadest range of optical transparency, and the highest refractive index. It also exhibits exceptional wear resistance, as well as superior acoustic properties, radiation resistance, and corrosion resistance. In short, diamond is the most perfect functional material in the material world to date. Due to its potential applications in military and various sectors of the economy, diamond powder has garnered increasing attention, leading to advancements in its production technology.

Applications of Nanotechnology in the Chemical Industry

Nanoparticles have several advantages as photocatalysts. First, their small particle size and large specific surface area result in higher photocatalytic efficiency. Additionally, the electrons and holes generated by the nanoparticles are less likely to recombine before reaching the surface, allowing for a higher quantity of charge carriers (electrons and holes) to participate in chemical reactions, thus increasing the activity. Furthermore, nanoparticles often exhibit transparency when dispersed in a medium, making it easier to study charge transfer, proton transfer, and the effects of semiconductor energy levels and surface state densities using optical methods.

Manufacturing Process of Grinding Wheels

Grinding wheels are an essential consumable in the general tool processing industry. You often see diamond grinding wheels being used in factories, but have you ever wondered how they are made? What are the processes and techniques involved in their production? Let us take you behind the scenes to uncover the top-level production secrets of diamond grinding wheel manufacturers.

Selection of Mold Steel Materials

The appearance of steel patterns on molds usually has two main causes: One is the quality of steel material ,many mold manufacturers choose lower-quality steel to save costs, which can result in surface patterns and fine lines after the molds undergo polishing. Under light, these patterns can cause distortion, and polishing can only alleviate the visibility of these steel patterns. The other reason is the polishing technician lacks adequate skills, it may also lead to the development of steel patterns on the mold surface.

When to Choose Polycrystalline and Monocrystalline?

We have previously discussed the differences between monocrystalline and polycrystalline diamonds, but how should they be applied in practice? In what situations should monocrystalline be chosen, and in what situations should polycrystalline be used? What kind of surface results can be expected from their use? Let’s dive in and find out.

Monocrystalline vs. Polycrystalline?

A monocrystalline, also known as a single crystal, is a crystal where the internal particles are arranged in a regular and periodic manner in three-dimensional space. In other words, the entire crystal is composed of a uniform spatial lattice in all three dimensions, and the arrangement of particles within the crystal is long-range ordered.

First Step in Choosing Polishing Materials

Many people often ask during the polishing process, “Should I use sandpaper for this surface, or opt for a specific grade of diamond paste abrasive?” When it comes to selecting polishing materials like diamond paste or the grit number of a grinding wheel, how do we determine which grit number can achieve the desired result? Let big data and statistical analysis provide you with the answer.

Prevention of Pitting

The formation of pitting during polishing—Is it a material issue or a technique problem? If it’s a technique issue, can it be prevented? To solve this problem, we first need to understand how it occurs. There are three main reasons behind this issue. Let’s take a closer look!
