Abstract
The invention discloses a new process for preparing high-permeability zirconium dioxide colorized porcelain piece used for denture, which comprises the following steps: weighing and mixing 93.5-99 percent of nanometer zirconium dioxide powder, 0.5-5 percent of cerium oxide and 0.5-1.5 of erbium oxide; filling the obtained mixture in a mould and pressing by a 60T press; pressing by isostatic press to form dense zirconium dioxide colorized porcelain piece; pre-sintering 1-2 hours at a high temperature of 1000-1100 DEG C; soaking in solution containing anhydrous ethanol to obtain a product after taking out. The new process disclosed by the invention does not need to fettle, and is more simple and convenient; by adding colorant cerium oxide and erbium oxide in formula, the zirconium dioxide colorized porcelain piece obtained by isostatic pressing has very high compactness which reaches 6.08, and has very high smoothness and stability; since being soaked in the solution containing anhydrous ethanol, the zirconium dioxide colorized porcelain piece has high permeability.
Description
Technical field
The present invention relates to gear division proprietary material field, relate in particular to a kind of high novel process of the colored porcelain piece of zirconium dioxide for property artificial tooth thoroughly of preparing.
Background technology
Full porcelain artificial tooth of the prior art is made by nano oxidized zirconium powder with zirconium oxide porcelain piece, it is the main raw of full porcelain tooth hat for dentistry fixed and repaired artificial tooth, full porcelain tooth hat is selected nano zirconium oxide powder completely, there is not hat in metal, the color and luster with the natural teeth of being similar to, intensity is high, and substituted metal baking-ceramic tooth, is widely used in dental prosthetic field just gradually.Yet existing zirconium oxide porcelain piece be mainly by batching, dress mould, dry-pressing, etc. static pressure, calcining, repaired biscuit polish to prepare, the operation of repaired biscuit polishing is more loaded down with trivial details consuming time, and needs sintering facing porcelain just can reach satisfied aesthetic.The zirconium oxide porcelain piece preparing, its compactness and light transmission are low, therefore in the urgent need to providing a kind of new technique to solve above problem.
Summary of the invention
Technical problem solved by the invention is to provide a kind of and prepares the high novel process of the colored porcelain piece of zirconium dioxide for property artificial tooth thoroughly, thereby solves the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Prepare high property artificial tooth thoroughly and be used in a novel process of soaking in the solution that contains dehydrated alcohol, comprise the steps:
(1) batching: take nano zirconium dioxide powder, cerium oxide, Erbium trioxide and mix, wherein the mass percent of nano zirconium dioxide powder is 93.5-99%, and the mass percent of cerium oxide is 0.5-5%, and the mass percent of Erbium trioxide is 0.5-1.5%;
(2) dress mould: (1) step gained mixture is packed in mould;
(3) dry-pressing: adopt 60T press to suppress;
(4) static pressure such as: adopt isostatic pressing machine compacting to form the colored porcelain piece of fine and close zirconium dioxide;
(5) pre-burning: pre-burning 1-2 hour under the high temperature of 1000-1100 ℃;
(6) soak: in containing the solution of dehydrated alcohol, soak, take out and obtain product.
The present invention has following beneficial effect:
Novel process of the present invention does not need to carry out repaired biscuit, and operation is more simple and convenient, has added tinting material cerium oxide and Erbium trioxide in formula, the colored porcelain piece of zirconium dioxide that adopts isostatic pressing to obtain, and its compactness is very high, can reach 6.08; There is very high planarization and stability; In containing the solution of dehydrated alcohol, soak, make it have high property thoroughly, the zirconium oxide porcelain piece making with traditional method is compared, and can increase more than 50% light transmission.
