    • A dielectric ceramic is made of a sintered body of a complex oxide including at least one element selected from the group consisting of Zr, Ti and Mn, at least one element selected from the group consisting of Mg, Zn and Co, and at least one element selected from the group consisting of Nb and Ta, wherein, the complex oxide is represented by a formula xZrO2-yTiO2-zA(1nullw)/3B(2nullw)/3O2 where nullAnull in the formula denotes at least one element selected from the group (A) consisting of Mg, Zn and Co, nullBnull denotes at one element selected from the group (B) consisting of Nb and Ta; x, y, z and w denote values in the respective ranges of 0.20nullxnull0.55, 0.40nullynull0.55, 0.05nullznull0.25, and 0nullwnull0.30, and x, y and z have a relationship represented as xnullynullznull1; MnO is present in a range of 0.1 mol % to 1.0 mol % to the complex oxide; and an average grain size of the dielectric ceramic is from 10 nullm to 70 nullm, thereby providing a dielectric ceramic that has a high dielectric constant (nullr) and an unloaded (Qu) value even in a comparatively low frequency region as a microwave region i.e., in a range of 0.4 GHz to 2.4 GHz and that realizes a desired temperature coefficient (nullf) of a resonant frequency with a high mechanical strength, and thus a dielectric device using the dielectric ceramic is provided.
    • 电介质陶瓷由包含选自Zr,Ti和Mn中的至少一种元素的复合氧化物的烧结体,选自Mg,Zn和Co中的至少一种元素和至少一种 元素选自Nb和Ta,其中,复合氧化物由式xZrO 2 -yTiO 2 -ZA(1 + w)/ 3B(2-w)/ 3O2表示,其中式中的“A”至少表示 选自由Mg,Zn和Co组成的组(A)中的一种元素,“B”表示选自Nb和Ta组成的组(B)中的一种元素; x,y,z和w分别表示0.20 <= x <= 0.55,0.40 <= y <= 0.55,0.05 <= z <= 0.25,0 <= w <0.30的各个范围内的值,x, y和z具有表示为x + y + z = 1的关系; MnO以0.1mol%至1.0mol%的范围存在于复合氧化物中; 并且电介质陶瓷的平均晶粒尺寸为10μm至70μm,从而提供即使在作为微波区域的较低频率区域中也具有高介电常数(epsir)和无载(Qu)值的电介质陶瓷,即 ,在0.4GHz至2.4GHz的范围内,并且实现具有高机械强度的谐振频率的期望温度系数(tauf),因此提供了使用电介质陶瓷的电介质器件。
