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.
