Ceramic sheet, method for manufacturing ceramic sheet, and green sheet
The invention relates to a ceramic sheet, a method for manufacturing a ceramic sheet, and a green sheet. According to the present invention, provided is a technique with which it is possible to obtain a ceramic sheet having excellent surface smoothness without causing a significant decrease in heat dissipation properties. In the ceramic sheet (1) according to one embodiment of the technology disclosed herein, the average aspect ratio of ceramic particles (10) is 1.2 or more, the sheet thickness (T) is 150 [mu] m or more, and a smooth region (20) in which the average orientation angle ([theta] 1) of the ceramic particles (10) is 20 DEG or less is formed at least in a sheet surface layer (A1). A heat dispersion region (30) in which the average value of the orientation angle ([theta] 2) of the ceramic particles (10) is 25 DEG or more is formed at least in a sheet interior (A2). By forming the smooth region (20) on the sheet surface layer (A1), particles can be prevented from protruding from the sheet, and excellent surface smoothness can be obtained. Furthermore, since the heat dispersion region (30) is formed in the sheet interior (A2), a significant decrease in heat dissipation performance due to the formation of the smooth region (20) can be suppressed.
本发明涉及陶瓷片、陶瓷片的制造方法和生片。根据本发明，提供可以得到不产生散热性的大幅降低且具有优异的表面平滑性的陶瓷片的技术。作为此处公开的技术的一方式的陶瓷片(1)的陶瓷颗粒(10)的平均长宽比为1.2以上，且片厚度T为150μm以上，至少在片表层(A1)形成有陶瓷颗粒(10)的取向角度(θ1)的平均值为20°以下的平滑区域(20)，至少在片内部(A2)形成有陶瓷颗粒(10)的取向角度(θ2)的平均值为25°以上的热分散区域(30)。通过在片表层(A1)形成上述平滑区域(20)，从而可以防止颗粒从片突出，得到优异的表面平滑性。另外，由于在片内部(A2)形成热分散区域(30)，因此可以抑制平滑区域(20)的形成所导致的散热性的大幅降低。
