Technical field
This utility model relates to a kind of high-strength carborundum mullite composite calcining-endure plate, belongs to the production skill of electronic ceramics product
Art field.
Background technology
High-strength carborundum mullite composite calcining-endure plate is mainly used in electronic ceramics burning kiln.Electronic ceramics refers to profit
With the electricity of ceramic material, thermal and magnetic, gas, power, the ceramic of the special performance such as infrared.Kind mainly includes electronic substrates, integrated
Block sealing member, resistor, capacitor, inducer and the radio frequency element such as wave filter, descriminator, various kinds of sensors, change
Energy device, over-voltage and over-current protector, battery, magnetic device etc..Electronic ceramics calcination equipment is many with pushed bat kiln, shuttle kiln, top-hat kiln
Being main, some yield is big, firing range is wider, then can use tunnel without the most rigid ferrite of material etc. of special atmosphere requirement
Road kiln, roller kilns burn till.Depending on the device shape of kiln furnitures used is with burning till shape of product size and kiln type, be mostly load bearing board, crucible,
Push pedal etc..Holding burning product is that lamination holds burning, and every layer of load bearing board adds product weight about 1kg, general folded about 10 layers, therefore load bearing board
Maximum possible bears the pressure of tens kilograms.Meanwhile, frictional force when thrust when bear mobile and loading/unloading products, more than
Secondary cold cycling, therefore, uses environment very severe.
Load bearing board select on, electronic ceramics and normal silicate ceramic phase ratio, except load bearing board to be considered refractoriness,
Outside mechanical strength, heat stability and use cost, the chemical stability (inertia) of load bearing board to be paid special attention to, it is to avoid with held
Burn product generation chemical reaction and affect the performance of product.Along with ceramic material and device sintering process and equipment not
Disconnected improving, the load bearing board such as traditional clayey, High-Alumina, silicon nitride combined silicon carbide matter cannot meet use requirement, it is desirable to
Load bearing board possesses the performance such as high resistance to reactivity, high-strength low heavy, length in service life.
Summary of the invention
(1) to solve the technical problem that
For solving the problems referred to above, the utility model proposes a kind of high-strength carborundum mullite composite calcining-endure plate.
(2) technical scheme
High-strength carborundum mullite composite calcining-endure plate of the present utility model, including sandwich setter plate body, described three
Mingzhi's load bearing board body includes silicon carbide layer and the mullite layer being enclosed in outside described silicon carbide layer, and described mullite layer presents one
Planting mullite particle network-like structure, described sandwich setter plate body upper and lower surface four edge is respectively equipped with and supports the use
Connecting groove and engagement plate, described sandwich setter plate body upper and lower surface is the most through is provided with micro-hole.
As preferred technical scheme, the gap in described mullite layer is filled with corundum in granules shape crystal, with described
Mullite particle network-like structure in mullite layer forms continuous print staggered-mesh framing structure.
As preferred technical scheme, in described silicon carbide layer, Uniform Doped has nanoparticle.
Rib all it is evenly distributed with as in preferred technical scheme, described silicon carbide layer and mullite layer.
(3) beneficial effect
Compared with prior art, it has the advantages that high strength carbonizing of the present utility model to this utility model
Silicon mullite composite calcining-endure plate, intensity is high, and load-bearing is big, has good anti-external agency reactivity and thermal shock resistance, uses
Life-span is greatly prolonged.

Detailed description of the invention
A kind of high-strength carborundum mullite composite calcining-endure plate, including sandwich setter plate body 1, institute
State sandwich setter plate body 1 and include silicon carbide layer 2 and the mullite layer 3 being enclosed in outside described silicon carbide layer 2, described mullite
Layer 3 presents a kind of mullite particle network-like structure, and described sandwich setter plate body 1 upper and lower surface four edge sets respectively
Having matching used connecting groove 4 and engagement plate 5, described sandwich setter plate body 1 upper and lower surface is the most through is provided with micro-hole.
Further, the gap in described mullite layer 3 is filled with corundum in granules shape crystal, with described mullite layer 3
In mullite particle network-like structure formed continuous print staggered-mesh framing structure, corundum in granules can play the increasing of granule
By force, toughening effect, mullite particle is filled in the space of corundum in granules, and the existence of mullite crystal can function similarly to
Fiber and the enhancing of granule, toughening effect, both occupied states are all highly beneficial to the mechanical behavior under high temperature improving load bearing board.
Further, in described silicon carbide layer 2, Uniform Doped has nanoparticle, nanoparticle to be introduced by sial molten
Glue additive is at high temperature formed in situ nanometer or submicron alumina particle, and these are conducive to the refinement of matrix grain and do not come
The formation of stone phase, and the thermal shock resistance of load bearing board is improved by the mechanism such as transformation toughening, particulate reinforcement.
Further, all it is evenly distributed with rib in described silicon carbide layer 2 and mullite layer 3, improves composite calcining-endure plate
Load-bearing property.
High-strength carborundum mullite composite calcining-endure plate of the present utility model, intensity is high, and load-bearing is big, have good anti-outside
Portion's medium reactivity and thermal shock resistance, be greatly prolonged service life.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel spirit and scope are defined.On the premise of without departing from this utility model design concept, this area ordinary person couple
Various modification that the technical solution of the utility model is made and improvement, all should drop into protection domain of the present utility model, this reality
With the novel technology contents being claimed, all record in detail in the claims.
