陶瓷材料在人类生活和现代化建设中是不可缺少的一种材料。传统的陶瓷材料具有硬度高、耐腐蚀性强、耐磨性强、绝缘性强、热导率低、热稳定性好等优点,但其抗拉强度较低,塑性和韧性很差,容易产生碎裂。随着材料科学的不断发展,各种新型的陶瓷材料相继产生,很大程度上改善了传统陶瓷材料的不足。
氧化锆(ZrO2)作为一种新型陶瓷材料,除了具有传统的陶瓷材料的优点外,还同时具有较好的韧性,是耐火材料、高温结构材料、生物材料、和电子材料的重要原料,在工业生产中得到了广泛应用。
随着生活水平的提高,人们对生活品质及外在形象的要求也越来越高,而且人们对审美要求也日趋多样化,导致人们对日常生活中使用的产品的外观的重视程度也逐渐增加,外形美观已经成为产品品质的重要的考量内容。然而现有的陶瓷材料的颜色一般较为单一,且多为白、灰等颜色,当将陶瓷材料应用于产品的外观部分,尤其是当将陶瓷材料应用于穿戴用品及便携产品时,例如手表表带、饰品、手机外壳等,虽然具有较好的使用性能,但陶瓷材料的颜色会影响产品的美观度,无法满足不同用户的不同类型的审美需求,降低了产品的市场竞争力。
