Preparation and Molding Methods of Zirconia Ceramic

At present, the most striking preparation method of zirconia ceramics is ultra-high temperature technology. This technology is inexpensive for zirconia ceramic preparing, as well as the preparation of new glass materials, such as optical fiber, magnetic glass, hybrid integrated circuit board, zero-expansion crystallized glass, high-strength glass, artificial bone and tooth stick. In addition, ultra-high temperature technology can also be used to develop materials such as tantalum, molybdenum, tungsten, vanadium-iron alloy and titanium that can be used in space flight, ocean, nuclear fusion and other fields.

The zirconia ceramic ultra-high temperature technology has the following advantages: it can produce substances that cannot be produced by conventional methods; it can obtain substances with extremely high purity: productivity can be greatly improved; and the operation procedure can be simplified and easy.

In addition to ultra-high temperature technology, preparation of zirconia powder by dissolution method, preparation of ceramic powder by chemical vapor deposition, production of mullite ultrafine powder by sol K gel method, and plasma gas phase reaction method have also attracted people's attention. Most of these methods have been developed in recent years or have been improved in the near future.

The zirconia ceramic forming method is roughly classified into two types: dry forming and wet forming. Dry forming includes steel die pressing, isostatic pressing, ultrahigh pressure forming, powder electromagnetic forming, etc.; wet forming can be roughly divided into plastic molding and colloidal casting molding. In addition to the above two methods, in recent years, colloidal molding and solid moldless molding technology have also achieved rapid development in the formation of zirconia ceramics.

The future development of zirconia ceramic forming technology will focus on the following aspects:

a. further developing various applications of various zirconia ceramic moldless forming techniques in preparing different ceramic materials;

b. zirconia ceramics have more complex structural layers and designs for interspersing, interlacing, joining structures and three-dimensional changes in the layers;

c. Structural design and manufacture of large-sized shaped parts of zirconia ceramics;

d. Manufacture and practical application of zirconia ceramic microstructure;

e. Further develop new technologies for non-polluting and environmental coordination of zirconia ceramics.

Boron Nitride Ceramic Properties

Boron nitride is a white solid ceramic material, with a nickname of "white graphite" because of its similar appearance and structure. Boron nitride ceramic is an excellent material which has low porosity, good thermal conductivity, low dielectric constant and superior dielectric strength. It is easily machined into complex shapes, and then ready for use without additional heat-treating or firing operations. Boron nitride has a variety of different variants: hexagonal boron nitride (h-BN), rhombohedral boron nitride (r-BN), cubic boron nitride (c-BN) and wurtzite boron nitride (w-BN). The most commonly used in the industry are h-BN and c-BN. H-BN & C-BN Hexagonal boron nitride, abbreviated as hBN, is an electron body having a layered structure similar to graphite. It has good lubricity, electrical insulation, thermal conductivity, and chemical resistance, and also has the ability to absorb neutrons. It is made of nitrogen (such as urea, melamine, etc.) and boron (b...

Graphene + Hexagonal Boron Nitride = New Transistor

Graphene has been fascinating to scientists since its discovery more than a decade ago. This carbon material with only one atomic thickness has excellent electronic properties, strength and ultra-lightweight. Its use is also expanding, but how to implant the energy gap (bandgap/semiconductor or insulator valence band tip to the energy gap at the bottom of the conduction band) to make transistors and other electronic devices, but always let the researchers do nothing. Graphene Researchers at the Massachusetts Institute of Technology (MIT) have made major breakthroughs in this area and are even expected to change some of the theoretical predictions of graphene physics. They introduced another material with single atomic thickness and properties similar to graphene: hexagonal boron nitride (HBN) . They placed a layer of graphene on the HBN, and the resulting hybrid material had both the conductive properties of graphene and finally the energy gap necessary to build the transis...

Main Application Fields of Lanthanum Hexaboride Ceramic Materials

Lanthanum hexaboride LaB6 cathode material: Lanthanum hexaboride has the characteristics of high emission current density and low evaporation rate at high temperature. Therefore, as a cathode material, it has gradually replaced some tungsten cathodes in industrial applications. At present, the main application fields of lanthanum hexaboride LaB6 cathode materials are as follows: 1 Microwave vacuum electronic devices and ion thrusters in the fields of military and space technology, and new technology industries such as display and imaging devices and electron beam lasers with high definition and high current emissivity required by civil and military industries. In these high-tech industries, the demand for low temperature, high uniform emission, high current emission density and high lifetime cathode materials has been very tight. 2 Electron beam welding industry. For electron beam welders, electron beam melting and cutting equipment. The cathode material should meet the re...
