Crystalline glass powder, glass ceramic dielectric material, sintered body, and high-frequency circuit member
Provided are a crystalline glass powder and a glass ceramic dielectric material for producing a sintered body and a high-frequency circuit member. The sintered body can be fired at a temperature of 1000 DEG C or less without discoloring the conductor Ag, and has a low dielectric loss tangent and a high bending strength in a high-frequency region of 20 GHz or more. The crystalline glass powder according to the present invention is characterized in that, during heat treatment, (CaxMg2-x) Si2O6 crystals (0.6 < = x < = 0.9) and (CaySr1-y) (Al2Si2O8) crystals (0.1 < = y < = 0.2) are precipitated as main crystals.
本发明提供用于制作烧结体和高频用电路部件的结晶性玻璃粉末和玻璃陶瓷电介质材料。该烧结体能够以1000℃以下的温度对导体Ag不变色地进行烧制并且在20GHz以上的高频区域具有低的介质损耗角正切和高的抗弯强度。本发明的结晶性玻璃粉末的特征在于：进行热处理时，作为主结晶，析出(CaxMg2－x)Si2O6结晶(0.6≤x≤0.9)和(CaySr1－y)(Al2Si2O8)结晶(0.1≤y≤0.2)。
