Tetra-Needle Like Zinc Oxide Whisker
Tetra-Needle like Zinc Oxide Whisker is a high tech material,which is a new product we are in the developing with a famous Chinese University,an ‘Enterprise-University Cooperation’ Project.Tetra-Needle Like Zinc Oxide Whisker has excellent properties for using in multi-industries.
Super High Strength:Tetra-Needle like ZnO Whisker as single crystal wurtzite structure,has almost no structural defects,belonging to the ideal crystal which has high mechanical strength and elastic modulus.The Tensile strength reached 1.0×104 mPa.while elastic modulus reached 3.5×105 mPa.Both of them are closing to the theoretical strength value.
*Isotropic:Special stereo Tetra-Needle structure,make it’s having the enhancement and the modified effect in fully isotropic.It ensures the isotropic of materials and product in the mechanical properties,size uniformity,thermal shrinkage,thermal deformation and other performance etc.
*Excellent Heat Resistance:Since the melting point of ZnO is higher than 1800℃,Tetra-Needle like ZnO Whisker could resist the high temperature of 1720℃.In atmosphere pressure of the air,the portion of the tip of Nano structure might be damaged in the temperature over 1000℃.
*Adjustable Electrical Properties:ZnO belongs to N-Type semiconductor.It could control electrical properties of conductive,piezoelectric and varistor by the way of doping.
*Nanometer Semiconductor Active:The special structure shows the special tip nano activity.The semiconductor properties of non-strict stoichiometric,has released active oxygen.Its macro performance is to anti bacterial and purificate environment of high efficient,broad-spectrum,and lasting.
