Electrostatic dissipation ceramic material and preparation thereof

Abstract

The invention relates to an electrostatic dissipation ceramic material and a method for the production thereof. The electrostatic dissipation ceramic takes a mixture of zirconia or aluminum oxide or zirconia and aluminum oxide as a matrix, and adds a proper titanium carbide as a resistivity regulator, and the adopted materials comprise (1) 70 to 90 percent of zirconia content and 10 to 30 percent of titanium carbide content by weight percentage; (2) 70 to 90 percent of aluminum oxide content and 10 to 30 percent of titanium carbide content by weight percentage; and (3) 20 to 60 percent of zirconia content and 20 to 60 percent of aluminum oxide content by weight percentage; and 10 to 30 percent of titanium carbide content by weight percentage. The electrostatic dissipation ceramic having a surface resistivity ranging from 10<5> to 10<10>ohms / square is made after mixing, forming and sintering. The material can be used for making antistatic electronic components and various antistatic tools and tool equipment.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and the ceramic materials have static electricity dissipating properties for safe discharge of electrostatic charges. Background technique [0002] Static electricity is ubiquitous in people's daily life and production work. As long as there is mutual friction, contact and separation, static electricity and static electricity discharge will inevitably occur. [0003] In the era of rapid development of science and technology, various microelectronics and optoelectronic devices are widely used. Electrostatic discharge (ESD) will change the electrical properties of semiconductor components, reduce their performance or even cause damage. Electrostatic discharge can cause disorder in the electronic system, resulting in failure or failure of equipment. In addition, electrostatic discharge produces electrostatic sparks, which become a safety hazard in the production of flammable and explosive...

AI Technical Summary

Problems solved by technology

At present, the most widely used and researched antistatic materials are mostly made by adding conductive materials such as metal and carbon black to polymers, which cannot meet the strength and hardness requirements of some tooling and tools for manufacturing materials, and it is also difficult to solve the existing problems of these materials. Easy aging, poor wear resistance, poor corrosion resistance, etc.

However, the static dissipative ceramic products currently sold are all adding oxide conductors or semiconductor materials to the zirconia matrix as resistance regulators. The mechanical and physical properties of the products are poor, the production technology is difficult, and the cost is high, resulting in very expensive products.
