Description
Technical field
The present invention relates to technical field of ceramic material, more particularly to a kind of ceramic burning-resisting board and preparation method thereof.
Background technology
Load bearing board is a kind of function ceramics, is carrier of the electronic component in sintering process, its quality and performance
Quality, directly affect the quality of burnt product, yield, energy consumption, cost etc..Qualified load bearing board needs the main performance requirements reached
For：It is indeformable in electronic component high temperature sintering, do not ftracture, and with stable chemical property and good thermal shock resistance.
Current line when firing Zinc-oxide piezoresistor product in the industry used load bearing board mainly have two kinds：One kind is to use
The load bearing board that Zinc-oxide piezoresistor waste material is pressed into, this load bearing board low intensity, cold-and-heat resistent circulation ability is poor, be easily deformed,
Cracking, service life are short；Another kind spills the common load bearing board of zirconia of thick zirconium powder or useless oxide powder and zinc for surface paving, this to hold
Though the properties of Zinc-oxide piezoresistor product can be ensured by burning plate, artificial paving is needed to spill thick zirconium powder or useless oxygen when using every time
Change zinc powder, operation wastes time and energy, and paving spills thick zirconium powder or the dosage of useless oxide powder and zinc is difficult to determine and controlled, cause it is artificial and
The waste of material, therefore production cost is higher.
Therefore, it is necessary to which it is long, easy to use to develop a kind of intensity height, high temperature resistant, service life, and fired suitable for carrying
The ceramic burning-resisting board of Zinc-oxide piezoresistor.
The content of the invention
Based on this, it is an object of the present invention to provide a kind of ceramic burning-resisting board, and it has intensity height, high temperature resistant, corrosion resistant
