Abstract
The present invention is one kind of silvery white zirconia ceramic product and its making process. The silvery white zirconia ceramic product has zirconia base and one layer of zirconium carbide film, which is formed through heating white zirconia product at 1500-1600 deg.c inside carbon atmosphere in a vacuum furnace and maintaining for 2-5 hr. The silvery white zirconia ceramic product is environment friendly, radiation-proof, low in production cost and simple in production process.
Description
Technical field
The present invention relates to a kind of silvery white zirconia ceramic product and manufacture method thereof, relate in particular to a kind of environmental protection, radioprotective, the difficult allergy of human body, do not waste production cost, the simple silvery white zirconia ceramic product of production technique and manufacture method thereof.
Background technology
Traditional zirconium white ZrO2 itself is a white powder, and mix colorant on market various colours and white is arranged, but does not have argenteous in the product that final production is come out.Traditional manufacturing processed is: batch mixing → mix glue → come unstuck → sintering → polishing (temperature 1400 ℃～1580 ℃ time be white in color zirconium white), can not make argenteous.
Summary of the invention
The technical problem to be solved in the present invention is: conventional oxidation zircon ceramic goods can't produce silvery white product.
For solving the problems of the technologies described above, the present invention proposes following technical scheme: a kind of silvery white zirconia ceramic product, its material are also to be provided with one deck zirconium carbide film on the zirconium white base material.
This zirconium carbide film is to use carbon atmosphere vacuum oven, and the zirconium white product of white is warming up to 1500 ℃～1600 ℃ in stove, is incubated after 2～5 hours, at the film of ZrO2 product surface formation.
The present invention also proposes a kind of manufacture method of making described silvery white zirconia ceramic product, and it may further comprise the steps:
Step 1: mix the glue batch mixing: be ratio that mix at the zirconium powder end of 20% wax and resene and 80% under the low temperature;
Step 2: injection molding: said mixture is injected effigurate die for molding;
Step 3: binder removal: heat,, when 500 degree-600 are spent, all volatilize along with the rising wax and the resene of temperature begins to dissolve;
Step 4: sintering: spend through continuing to be warmed up to 1400 degree-1580 under oxidizing atmosphere behind the binder removal, sinter molding becomes white zirconium white;
Step 5: sanding and polishing;
Step 6: vacuum sintering: the ZrO2 of the white behind the sanding and polishing aftershaping is put into carbon atmosphere vacuum oven white zirconium white product is warming up to 1500 ℃～1600 ℃ at stove, be incubated after 2～5 hours, form the argenteous ZrC film of one deck high rigidity anti-scratch at the ZrO2 product surface.
The present invention has following beneficial effect: generally be used for producing in the carbon atmosphere vacuum oven of wolfram steel product, the zirconium white product of white after furnace high-temperature reaction, form the argenteous zirconium carbide film of one deck high rigidity anti-scratch at the ZrO2 product surface, this product has environmental protection, radioprotective, human body and is difficult for characteristics such as allergy, produce with original carbon atmosphere vacuum oven, do not waste production cost, production technique is simple.
Embodiment
The present invention proposes a kind of silvery white zirconia ceramic product, comprises bowl, dish, basin, jar, vase or the like, and shape also can be not limited to a certain particular form, but its material is also to be provided with one deck zirconium carbide (ZrC) film on zirconium white (ZrO2) base material.
This zirconium carbide film is a kind of silvery white, high hardness material, can produce good surface appearance effect (being equal to stainless steel) after polished finish.
This zirconium carbide film is to use the existing carbon atmosphere vacuum oven that generally is used for producing the wolfram steel product, the zirconium white product of white is warming up to 1500 ℃～1600 ℃ in stove, be incubated after 2～5 hours, at the film of ZrO2 product surface formation one deck high rigidity anti-scratch, i.e. this zirconium carbide film.
Chemical equation is as follows: ZrO2+C → ZrC+CO2
The present invention also provides a kind of manufacture method of making above-mentioned silvery white zirconia ceramic product, and it may further comprise the steps:
Step 1: mix the glue batch mixing: be ratio that mix at the zirconium powder end of 20% wax and resene (PPE class) and 80% under the low temperature;
Step 2: injection molding: said mixture is injected effigurate die for molding;
Step 3: binder removal: heat,, when 500 degree-600 are spent, all volatilize along with the rising wax and the resene of temperature begins to dissolve;
Step 4: sintering: binder removal is after continuous 1400 degree-1580 degree that are warmed up to of adopting, the remaining at last ZrO2 that has tied the white after the film moulding;
Step 5: sanding and polishing;
Step 6: vacuum sintering: the ZrO2 of the white behind the sanding and polishing aftershaping is put into carbon atmosphere vacuum oven white zirconium white product is warming up to 1500 ℃～1600 ℃ at stove, be incubated after 2～5 hours, form the argenteous ZrC film of one deck high rigidity anti-scratch at the ZrO2 product surface;
ZrO2+C (↑ high temperature) → ZrC+CO2
Step 7: polishing: through forming the identical finished product of similar stainless steel color after the polished finish.
Among the present invention, generally be used for producing in the carbon atmosphere vacuum drying oven of wolfram steel product, the oxygen of white Change the zirconium product after the furnace high-temperature reaction, form the silver of one deck high rigidity anti-scratch at the ZrO2 product surface The zirconium carbide film of white, this product have environmental protection, radiation proof, human body and are difficult for the characteristics such as allergy, with former Production cost is not wasted in the carbon atmosphere vacuum drying oven production that has, and production technology is simple.
