氧化鋯陶瓷刀是屬于現代技術陶瓷三個主要領域結構陶瓷領域氧化鋯系列產品之一，號稱“陶瓷鋼”。具有耐腐蝕不生銹，高硬度，耐磨，健康環保等一系列金屬刀具無法比擬的優點。
其耐磨性是金屬刀具的幾十倍，且具有良好的韌性，無靜電、摩擦力小、刀刃口鋒利、切削輕快、不卷刀、耐用無毒、不氧化、可耐各種酸堿有機物的腐蝕、化學性能穩定。鋯的熔點則在1800度以上，二氧化鋯的熔點更是高達2700度以上，所以鋯作為航空航天材料，其各方面的性能成型大大優越于鈦。
在建筑陶瓷釉料中多使用鋯英石，一般用量為8％—12％。并為“釉(you)下白”的主(zhu)要原料，氧化鋯為黃(huang)綠色顏料良好的助色劑，若想獲得較(jiao)好的釩鋯黃(huang)顏料必(bi)須選(xuan)用(yong)質純的氧化鋯。（圖/文hytlfdc.com）
中譯英：
The wear resistance of the metal cutting tool is dozens of times, and has good toughness, no static electricity, small friction force, mouth sharp blade, cutting a roll knife, not durable, non-toxic, no oxidation, is resistant to various kinds of acid and organic corrosion, chemical stable performance. Zirconium melting point is above 1800 degree, two zirconium oxide melting point is as high as2700 degrees, so the zirconium as aerospace materials, its various aspects performance molding greatly superior to titanium.

In the construction of ceramic glaze with zircon, general dosage is 8% - 12%. And " underglaze white" is the main raw material, zirconia yellow-green pigments good color agent, to obtain better vanadium zirconium yellow pigment must choose the pure zirconia.
