Abstract
The invention relates a zirconia-toughened mullite ceramic material and manufacturing method thereof, which is manufactured through modern toughening and strengthening technologies with zirconium silicate and Alpha-aluminum oxide as a substrate, yttrium oxide, magnesium oxide, calcium oxide and titanium oxide as a mineralizer, and mullite as a seed crystal. The material is toughened and strengthened through the modifying treatment and the green compact has good uniformity and compactness with the aid of an isostatic pressing. The sintering process is completed within one time in the shuttle kiln under normal pressure and high temperature conditions, having a uniform temperature and low cost. Compared with an aluminum oxide ceramic material, the invention has advantages of high strength, high tenacity, high wear resistance and simple process; the dramatic reduction of sintering temperature can achieve the purpose of energy efficiency.
Description
Technical field
The present invention relates to a kind of Zirconium oxide plasticizing mullite ceramic material and preparation method.
Background technology
Conventional oxidation lead (corundum) structural ceramic material, it has, and starting material are extensive and cheap, and technical equipment requires low, thereby is extensive use of, and plumbous oxide structural ceramics firing temperature is higher, generally reaches more than 1600 ℃, and energy consumption is serious; Simultaneously, because the fracture toughness property of plumbous oxide pottery is lower, so its bending strength and wear resisting property are relatively poor; So to ask for something fastness to rubbing and the higher field of physical strength, as the plumbous well ceramic liner of oil, just can not be with the plumbous oxide ceramic material.Mechanism's intensity of zirconia ceramics and fracture toughness property are all very high, but cost is very high.The simultaneous oxidation zircon ceramic is easy to generate low temperature aging, so be difficult to large-scale promotion.The plumbous oxide stupalith, wear resistance is bad, and its work-ing life is short, poor toughness, and the intensity aspect is not high, firing temperature and energy consumption height.
Summary of the invention
The objective of the invention is to overcome the defective of alumina ceramic material, a kind of Zirconium oxide plasticizing mullite ceramic material and preparation method are provided.
Technical solution of the present invention is the shortcoming and defect that exists according to background technology, with ZrSiO
