Description
Technical field
The invention belongs to technical field prepared by ceramic material, be specifically related to a kind of anti-electrostatic ceramic material and preparation side thereof
Method.
Background technology
General ceramic material has the highest resistivity, easy Accumulating charge, the accumulation of these electric charges may bring as
Above-mentioned multiple harm.Annual have associated electrostatic to endanger damnous report, is therefore badly in need of more than developmental research can solve
The ceramic material of problem.
Electrostatic, is a kind of electric charge remained static.When accumulation is the formation of on certain object or during surface
Electrostatic, and electric charge is divided into positive charge and negative charge two kinds, say, that electrostatic phenomenon is also classified into two kinds i.e. positive electrostatic and negative electrostatic.
It is the formation of positive electrostatic when positive charge is gathered on certain object, is the formation of bearing when negative charge is gathered on certain object
Electrostatic, but either positive electrostatic still bears electrostatic, when static electrification object contacts zero potential object (ground connection object) or has electricity with it
Electric charge all can be occurred to shift during the object of potential difference, it is simply that we are daily sees spark static discharge phenomenon.
In the most growing electronics industry epoch, various microelectronics, photoelectron original paper application widely, and quiet
Discharge of electricity can be destroyed electronic original part, the electrical property changing semiconductor components and devices, destroy electronic system, causes whole equipment fault
Or it is malfunctioning；Meanwhile, produce electrostatic spark, equipment of Flammable and Explosive Materials of easily igniting during electrostatic charge release, cause considerable risk
And economic loss；Additionally, electrostatic easily sucks foul in clean environment, such as dust, foreign particles, easily making can not be mutual
The product of contact sticks together, and these all can cause great loss.Electrostatic is as the universal physical phenomenon of one, the most during the last ten years
Applying with the extensive of macromolecular material along with developing rapidly of integrated circuit, the active force of electrostatic, electric discharge and induction are drawn
The harm risen is extremely serious, and the U.S. adds up, and American Electronic industry department causes damage up to 10,000,000,000 beautiful because of electrostatic hazard every year
Unit, the loss that Britain's electronic product causes because of electrostatic every year is 2,000,000,000 pounds, many in the defective work of NEC components and parts
Harm in 45% is because what static discharge (ESD) caused.
Owing to electrostatic hazard is the hugest, therefore cause the great attention of people.Prepare many anti-quiet at present
The material of electricity, design many electrostatic discharge dissipative apparatus, be used for preventing static discharge phenomenon generation.Quiet for preventing
The static dissipative material of electricity should be semi-insulated, and its volume resistance range is 104To 1011Ω-cm, when this kind of material is rubbed
During wiping, the electrostatic charge that its surface produces can spread faster and leak.Particularly, it is 10 when the specific insulation of material6Arrive
108Ω-cm, the electrostatic of material surface can at utmost prevent static discharge pair with the slowly sustained release of speed more slowly
The destruction of product.The most most widely used antistatic material, is mostly by adding the conducting powder such as white carbon black, metal powder in the plastic
System becomes, and utilizes conductive powder body to be evenly distributed on plastics inner and forms conductive network, reduces the resistivity of plastics itself, thus reach
Purpose to electrostatic dissipation.And ceramic material has the advantages such as good wearability, corrosion-resistant, high temperature resistant, good rigidly, it is preferable
Antistatic material.Be presently used for the special cermacis of structural member mainly have aluminium oxide ceramics, zirconia ceramics, silicon nitride ceramics,
Silicon carbide ceramics etc..
