Photochromic ceramic powder as well as preparation method and application thereof
The invention relates to the technical field of photochromic ceramic powder, in particular to photochromic ceramic powder and a preparation method and application thereof.The preparation method comprises the steps that ammonium dihydrogen phosphate, lithium carbonate and titanium dioxide are weighed according to the stoichiometric ratio, a certain amount of tungsten trioxide and cobalt oxide are weighed to serve as doping components to be mixed in a mortar, ethyl alcohol serves as a mixing agent, and the mixture is stirred to be uniform; grinding in a mortar until the mixture is dried to obtain a required sample; the sample is placed in a box-type furnace and sintered through a high-temperature solid-phase method, the pre-sintering temperature is 240 DEG C, the heat preservation time is 3 h, then the temperature is 1000 DEG C, the heating time is 260 min, and the sintering time in air is 4 h. And after the box-type furnace is naturally cooled to room temperature, taking out a sample, and crushing and grinding the sample in a ceramic mortar to finally obtain the ceramic powder with reversible photochromic performance. The ceramic powder is changed from light purple to brown under the irradiation of a 365nm lamp, and the original state can be recovered after the temperature is kept at 600 DEG C for 5 hours; a new substrate is provided for the field of inorganic photochromic materials.
本发明涉及光致变色陶瓷粉技术领域，具体涉及一种光致变色陶瓷粉及其制备方法与应用，按照化学计量比称量磷酸二氢氨、碳酸锂、二氧化钛，并称量一定量的三氧化钨和氧化钴作为掺杂成分混合在研钵中，以酒精做混合剂，在研钵中研磨至干燥，得到所需样品；将样品置于箱式炉中，采取高温固相法烧结，预烧结温度为240℃，保温时间为3h，后以1000℃，升温时间为260min，空气中烧结时间4小时。待箱式炉自然冷却至室温取出样品，在陶瓷研钵中粉碎研磨，最终得到具备可逆光致变色性能的陶瓷粉。陶瓷粉在365nm灯照射下由淡紫色变为棕色，在600℃下保温5小时可恢复原始状态；为无机光致变色材料领域提供了一种新基质。
