99.99% high purity beta sic nano powders Our 4N nano β-SiC (99.99% purity) is precision-synthesized via CVD, delivering ultra-fine particle size with exceptional sintering activity for high-density ceramic components. It thrives in the most demanding semiconductor environments — from CMP chucks and lithography stages to plasma etch focus rings and chamber liners. Its chemical inertness and minimal metal impurity outgassing maximize chip yield where it matters most. Trusted by leading fabs and equipment makers worldwide. more
Monodisperse spherical Nano SiO₂ aqueous dispersion/colloid This transparent SiO₂ aqueous dispersion is synthesized via patented sol-gel technology, featuring optical excellence visible light transmittance and shelf life >18 months under ambient storage. It is widely used in electronics as low-k dielectric materials, in biomedicine as drug carriers, and in optics for anti-reflection coatings. more
Magnéli Phase Nano Titanium suboxide Ti₄O₇ Powder Magnéli phase Nano titanium suboxide (Ti₄O₇) is an advanced functional material with a unique crystal structure, appearing as a blue-black powder with a precisely controlled particle size of 200–300 nm and a purity of up to 99.9%. As an important member of the titanium oxide family, Ti₄O₇ combines excellent electrical conductivity, chemical stability, and catalytic activity, making it an ideal choice for new energy, environmental protection, and electronics applications. more
Boron Nitride Nanotubes(BNNTs): High Thermal Conductivity Heat Dissipation Fillers BNNTs share the tubular structure of carbon nanotubes but deliver fundamentally different properties: electrical insulation, superior thermal stability (up to 900°C in air), and high thermal conductivity. With a wide bandgap of ~5.5 eV, they offer consistent, predictable performance where CNTs fall short. more

Some nanomaterials for Thermochromic Application
Thermochromism refers to the phenomenon where a material undergoes color changes under temperature changes. This change is usually caused by changes in the electronic or molecular structure of the material. Its application principle mainly involves t...
Antibacterial Nano Silver Used in Plastics
According to traditional concept, plastic is smooth dense, difficult to attach and erosion of harmful microorganisms. But in fact, the plastic will be bacterial contamination. In disease prevention and health care, the pursuit of quality of life has become a fashion today, anti-bacterial nano silver powders timely out.
Antibacterial nano-silver is a new material with bacteriostatic and bactericidal properties, since the material itself is given antibacterial property, so that the microorganism may include bacteria, fungi, yeasts, algae and viruses maintain the growth and reproduction of the lower level. Nano silver antimicrobial material of various products, with health self-cleaning function, which can effectively prevent the spread of bacteria.
The new contact antibacterial mechanism of inorganic nano silver antimicrobial material different from the traditional stripping organic nano-antibacterial materials and inorganic photocatalyst nano material, its sterilization mechanism is positively charged when exposed to antibacterial ingredient is negatively charged after biological cells, each adsorption, membrane breakdown that effectively, is a cell protein denaturation, unable to breathe, metabolism and reproduction, until death, complete sterilization. At this time, did not make any antibacterial ingredient consumption remains the original antibacterial ability, so he can be long-term effective antimicrobial ability.
Hongwu manufacturers of inorganic nano silver antimicrobial powders stable performance, usually no additives and plastic raw materials and chemical reactions, and add a small number of processing is also very stable, so stable performance plastics after use.
Currently, our technology is more mature, low cost, and its price is only about a quarter of similar foreign products in the domestic market, and therefore has great competitiveness. After the product is made, the new high-profit, market efficiency is good, and therefore widely used. Such as antimicrobial nylon toothbrush, polyethylene cutting board, food packaging films, polypropylene bags, tableware, refrigerator interior, washing machines washing, have already passed in the test market, and some have been exported abroad.
Tests showed that you can also use inorganic nano material production following antibacterial plastic products: sanitary napkins, agricultural absorbent resin, tableware, drug packaging materials, agricultural film, food shelves and crates, cell phones and pagers shell, phone cases and keys, dishwashers, humidifiers, toys, teaching aids, syringes and infusion tube, aquaculture nets, chairs handrails.
