The history of nanotechnology

Overview of nano silicon powder

Nano-silicon refers to crystalline silicon particles with a diameter of fewer than 5 nanometers (one billion (1G) one meter). Nano silicon powder has the characteristics of high purity, small particle size, uniform distribution, large surface area, high surface activity, looseness, low bulk density, non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials, a semiconductor with a wide energy gap, and a high-power light source. Nano-silicon can be used in combination with graphite, carbon nanotubes, or nano-nitrogen to combine compounds such as titanium dioxide to make lithium battery cathode materials, which can increase the capacity and service life of lithium batteries. It is a new generation of electro-optic semiconductor material with a huge energy gap.

Nanotechnology is a high technology that emerged in the late 1980s. Its basic meaning is to study the composition of matter in the nanometer size range and to create new matter by directly manipulating and arranging atoms and molecules. The emergence of nanotechnology marks that human cognition has expanded to the atomic and molecular level, and it marks the arrival of a new era of human science and technology the era of nanotechnology.

Nanotechnology is science and technology based on much modern advanced science and technology. It is a combination of modern science (quantum mechanics, molecular biology) and modern technology (microelectronics, computer technology, high-resolution microscopy, and thermal analysis). product. Nanotechnology has penetrated into various fields of modern science and technology andhas formed much new research related to nanotechnologies, such as nanophysics, nanochemistry, nanomaterials, nanobiology, nanoelectronics, nanomanufacturing, and nanomechanics. All of these constitute nanotechnology.

In the middle of the 18th century, the first industrial revolution represented by the steam engine was a symbol of the application of millimeter technology, which brought mankind into the industrial era of replacing manpower with machinery. In the 20th century, the second industrial revolution represented by microelectronics was a sign of the application of micron technology, enabling mankind to enter a new era of computers and communication networks. It is foreseeable that emerging science and technology represented by nanotechnology will bring the third industrial revolution to mankind in the 21st century.

Although nanotechnology has created many new substances and materials for mankind, it will bring us profound changes in our cognitive concepts. Take electronic technology as an example. In today's micron era, microelectronics plays a decisive role in human development and life. In the era of nanotechnology, due to the decline of electronic devices' enthusiasm for nanometers and even single molecules, nanoelectronics is the future. The role of electronic technology development will be immeasurable.

Nanomaterials are an important foundation for the development of nanotechnology and the most important research object of nanotechnology. The basic units that makeup nanomaterials can be divided into three categories according to size:

1. Zero sizes. Refers to the three-dimensional dimensions in the space are all nanometers. Such as nano-scale particles, clusters, etc.

2. One-dimensional. Refers to the two-dimensional space on the nanoscale, such as nanowires, nanorods, nanotubes, etc.

3. Two-dimensional. This means that one dimension is at the nanometer scale in three dimensions, such as ultra-thin films, multilayer films, superlattices, etc.

With its new understanding of the material field, nanotechnology is undoubtedly setting off a technological revolution. Nanotechnology provides us with preliminary demonstrations on new materials, new energy, computer technology, biomedicine, and aerospace applications. At the same time, nanotechnology is not isolated. It involves many disciplines, such as quantum mechanics, materials science, colloidal chemistry, physical chemistry, polymer chemistry, biochemistry, condensed matter physics microelectronics technology. Interdisciplinary penetration can better help us understand nanoscience and master nanotechnology.

Application of nano silicon powder

1). Use nano silicon powder to make nano silicon wires for the cathode material of rechargeable lithium batteries,

Or use it as a positive electrode material for rechargeable lithium batteries in chevron graphite on the surface of nano silicon powder.

Increase the capacity and charge-discharge cycle indicators of rechargeable lithium batteries by more than three times;

2). Nano silicon powder is used in heat-resistant coatings and refractory materials;

3). Nano silicon can be coated in the coating to form a silicon nanofilm, which is heavily coated on solar energy;

4). Nano silicon powder and diamond are mixed under high pressure to form a silicon carbide-diamond composite material, which is used as a cutting tool.

This product should be stored in a dry, cool, and sealed environment, and not exposed to the air. In addition, avoid heavy pressure and transport it as a normal item.
