 Description:
It is a general and well-known fact that Nano-materials are behaving differently from their bulk material. Size and shape control many of the physical properties (viz., melting point, magnetism, Specific heat, conductivity, bandgap, etc.), luminescence, optical, chemical, and catalytic properties of nanomaterials. The present research has been done, based on these facts and the New Nano-sized Pb metallic semiconductor has been innovated. The photoluminescence study of lead Nanopowder confirms the emission of photons. It suggests the presence of a bandgap in the material and its semiconducting properties.
 A semiconductor is a material which has electrical conductivity between that of a conductor such As copper and an insulator such as glass. The conductivity of a semiconductor increases with increasing temperature, behavior opposite to that of a metal. The most common semiconducting materials are crystalline solids. They are defined by their unique electric conductive behavior. They can pass current more easily in one direction than the other. Their conductive properties can be modified by controlled addition of impurities or by the application of electrical fields or Light. Metal conductivity decreases with temperature increase because thermal vibrations of Crystal lattice disrupt the free movement of electrons. Bulk lead metal is a good conductor but lead Nanoparticles behaving differently and showing some resistance in four probe test. Semiconductor resistivity is indirectly proportional to temperature. It increases with decreasing temperature and vice versa. 4 eV bandgap value is the rough dividing line and it determines whether a material is a semiconductor (less than 4 eV) or an insulator (more than 4 eV).
 Semi-Conductor Mechanism in Pb Nanoparticles
 Metallic nanoparticles possess unique optical, electronic, chemical, and magnetic properties that are strikingly different from that of the individual atoms as well as their bulk counterparts. The optical properties of nanoparticles are closely related to size-induced changes in the electronic structure and directly reflect the size-dependent energy structure of the particles. Spectroscopic methods probe the energy differences between the two states for allowed transitions. The size effect on the optical absorption spectra of metallic nanocrystals is probably best known for the noble metal nanoparticles. Nanomaterials exhibit interesting size-dependent electrical, optical and magnetic properties which are different from both atomic and bulk- level. At the nanoscale, because of quantum mechanics effects, they behave differently as compared to bulk materials. Indeed the emerging properties are due to the quantity variation in a number of atoms i.e. in nanoparticles, a number of atoms are less than their bulk matter where millions of atoms together. Also, because of compactness, there are split into energy levels. So, even in magnetic applications, there is more control. For example, as the size decreases, the bandgap of material increases.

Lithium-ion secondary battery anode material precursors to prepare silicon-based anode material Fine ceramic, synthetic raw materials; such as silicon nitride and silicon carbide Because silicon monoxide fine powder is very active, it can be used as fine ceramic, synthetic raw materials, such as silicon nitride and silicon carbide fine ceramic powder raw materials. Used for the preparation of optical glass and semiconductor materials.
Evaporate it in a vacuum and coat it on the metal mirror surface of the optical instrument as a protective film. Preparation of semiconductor materials.
The hunt is on advanced battery materials with enhanced storage capacity, higher energy density, and better cycle characteristics than traditional lithium-ion batteries. Conventional lithium-ion batteries rely on graphite-based anodes, whose well-established properties aren’t ideal for meeting the growing consumer demand for high-performance electronics, such as smartphones, laptops, and electric vehicles. Current research focuses on developing new alternatives that perform better and are safer than lithium-ion, and Nanochemazone is leading the way.
Silicon monoxide is a promising alternative to graphite because of its high specific gravity, low volume expansion, and small initial surface area. Silicon-based anodes can increase capacity ten times over standard graphite, allowing smaller batteries to produce the same amount of power or increasing the ability of a battery of the same size. This is possible because of the internal channels within the silicon monoxide Nanospheres. These channels allow lithium ions to flow rapidly for quick charging, and they shorten the paths for a boost in power.
Nanochemazone offers a 99.99% pure silicon monoxide powder prepared using chemical vapor deposition, suitable for secondary battery anode material precursors to prepare silicon-based anode materials and fine ceramic, synthetic raw materials. Our silicon monoxide battery material is prized by researchers and innovators around the world for its quality, purity, and consistency.

They are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.
Being important cermet materials, tantalum carbides are commercially used in tool bits for cutting applications and are sometimes added to tungsten carbide alloys.
The melting points of tantalum carbides peak at about 3880 °C depending on the purity and measurement conditions; this value is among the highest for binary compounds. Only tantalum hafnium carbide may have a slightly higher melting point of about 3942 °C, whereas the melting point of hafnium carbide is comparable to that of TaC.
Tantalum Carbide Application:
Tantalum Carbide Powder Applications
1. Tantalum carbide is often added to tungsten carbide/cobalt (WC/Co) powder attritions to enhance the physical properties of the sintered structure. It also acts as a grain growth inhibitors preventing the formation of large grains, thus producing materials of optimal hardness.
2. It is also used as a coating for steel molds in the injection molding of aluminum alloys. While providing a hard, wear-resistant surface, it also provides a low friction mold surface.
3. Tantalum carbide is also used in the production of sharp instruments with extreme mechanical resistance and hardness.
4. It is also used in tool bits for cutting tools.
Tantalum carbide is widely used as a sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable material for aircraft and rockets in aerospace industries.
Nanochemazone specializes in producing high purity Tantalum Carbide Powder with the smallest possible average grain sizes for use in the preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low-Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns, and submicron (< 1 micron). We can also provide many materials in the nanoscale range.
