SUOYI Dental Material Manufacturer Economical Dental Lab Zirconia Blocks, Zirconium Blocks, Zirconia Disc, Zircounium Blank, Zirconia Blocks
Zirconium blocks are mainly divided into four types: HT (high permeability), ST (ultra permeability) UT, and HST
The visible light transmittance of white zirconia ceramic blocks can reach 49%, which is similar to that of glass ceramics, but the three-point bending strength is>600MPa, which is much higher than that of glass ceramics. It is particularly suitable for all zirconium aesthetic restoration of anterior teeth and also for all zirconium restoration of posterior teeth. Using staining solution in conjunction with all ceramic dentures, create a crystal clear and transparent restoration like jade.
Porcelain block is a kind of multi colored pre dyed ceramic block. It has five common colors, four layers of color are superimposed, and seven layers of color are gradually changed. There is no need to soak and brush the Dentin color, and it can highly simulate the natural tooth color. It is the preferred material for aesthetic restoration.
Adjust the position of the dental crown within the porcelain block according to clinical color requirements, and freely adjust the sintering temperature to a maximum temperature of 1450-1550 ℃. It is recommended to sinter at 1530 ℃. The standard setting is to use professional oxidized sugar polishing tools for polishing, and a perfect restoration can be obtained by simply glazing.

Dental yttrium stabilized zirconia powder, monoclinic nano zirconia powder, and yttrium stabilized zirconia powder. White powder.
3Y 5Y yttria stabilized zirconia is more and more widely used in dentistry. ZRO2 yttria stabilized tetragonal nano zirconia is the most widely used biomedical material at present. Its characteristics not only lie in its high breaking strength (>1000 MPa), high fracture toughness (>10 MPa · m1/2), which significantly slows down the behavior of slow cracking, but also this colored zirconia ceramic has better aesthetics, which can match the color of human teeth very well.
Zirconia powder used in dentistry is a nanoscale powder that can increase the aging performance of the product; The powder has good flowability and mold filling ability, and adhesive can be added optionally, suitable for dry pressing isostatic pressing molding; Uniform powder particles can reduce processing defects caused by uneven density; High affinity with coloring liquid, firm and uniform coloring, can avoid spots, color blocks, etc.
Yttrium stabilized zirconia for high transparency dentures
Biological nano zirconium powder is mainly used in the field of medical bioceramics for dental single crowns, bridge bodies, full crowns, roots, abutments, and human joints
Compared with traditional dental ceramic materials, yttria stabilized zirconia polycrystalline ceramics with yttrium oxide (Y2O3) as a stabilizer for high permeability dentures have received widespread attention due to their high toughness due to the stress induced phase transition toughening effect of metastable tetragonal zirconia towards monoclinic zirconia. High permeability yttrium stabilized zirconia for dentures is an excellent high-tech biomaterial, and it is currently recognized in the dental industry that both the price and quality of denture production are high permeability yttrium stabilized zirconia for dentures.
Nanometer YSZ is a new type of high-tech material with extensive and important applications. The preparation techniques of YSZ are mainly hydrothermal and reverse micelle methods.
Y2O3 stabilized ZrO2
(YSZ) Solid electrolyte with high oxygen ion conductivity, good mechanical properties, excellent oxidation and corrosion resistance
 and not reacting with electrode materials
 and other advantages to make oxygen sensors, high-temperature solid fuel cells, piezoelectric ceramics, ferroelectric ceramics, and
The main materials such as oxygen pump, and Yttrium(III) oxide stabilized zirconia powder’s ultra-fine grain size, particle uniformity and reasonable composition ratio are used to obtain high
The key to YSZ solid electrolyte is its conductivity and good mechanical strength. Therefore, the preparation of nano YSZ particles has always been a science of nanomaterial preparation
At present, people have studied and used the coprecipitation method, sol2gel method, hydrothermal method, coprecipitation gel method, alcohol water solution method, azeotropic distillation
There are many methods to prepare zirconia powder, such as distillation technology, microwave assisted method, reverse micelle method or micro lotion method.
