Dental opaque baked porcelain powder and particle size distribution method
The invention discloses a dental opaque baked porcelain powder and a particle size grading method, and relates to the dental opaque baked porcelain powder, the particle size range of porcelain powder particles is 0.2-20 [mu] m, the weight ratio of the porcelain powder particles with the median diameter of 5-7 [mu] m is 60%, the weight ratio of the porcelain powder particles with the median diameter of 0.3-0.5 [mu] m is 20%, and the weight ratio of the porcelain powder particles with the median diameter of 5-7 [mu] m is 20%. And the weight ratio of the ceramic powder particles with the median diameter of 8-11 microns is 20%. The invention further relates to a particle size grading method of the dental opaque baked porcelain powder, the method comprises a preferable porcelain powder particle size grading scheme obtained through two-stage screening, the dental opaque baked porcelain powder obtained through particle size optimization meets the better gold-porcelain bonding performance, can facilitate plastic stacking forming of body porcelain layer porcelain powder, and is easy to prepare, low in cost and suitable for industrial production. And a contribution is made to the performance improvement of the opaque baked porcelain powder for the dental department.
本发明公开了一种牙科用遮色烤瓷粉及粒度级配方法，涉及一种牙科用遮色烤瓷粉，所述瓷粉颗粒的粒径范围是0.2～20μm，且其中的中位径为5‑7μm的瓷粉颗粒的重量占比为60％，中位径为0.3～0.5μm的瓷粉颗粒的重量占比为20％，中位径为8～11μm的瓷粉颗粒的重量占比为20％。还涉及一种牙科用遮色烤瓷粉的粒度级配方法，包括经过两级筛选得到优选的瓷粉粒度级配方案，本发明通过优化粒度得到的牙科用遮色烤瓷粉，同时满足具有更好的金瓷结合性能，又能利于体瓷层瓷粉的堆塑成型，并且制备容易，成本低，对牙科用遮色烤瓷粉的性能改进做出了贡献。
