<p>PURPOSE:To obtain a glazed base plate free of crack development even when matrix wiring is hot-walded by a method in which a crylstalline glaze is atatched on the whole surface of a ceramic base plate and a convexed glaze layer formed only on the place where a striped heating resistor is to be formed on the crystalline glaze layer. CONSTITUTION:For example, A slurry of crystalline glaze powder with a composition containing 45% SiO2, 11% Al2O3, 0.5% MgO, 1.5% CaO, 32% BaO, 7% ZnO, and 3% ZrO2 is coated on a creamic base plate 11 240mm. in length, 50mm. in width and 1.5mm. in thick, having an alumina content of 97%, and then baked to form a crystalline glaze layer 12 of a thickness of 10-100mum. Then, a noncrystalline glaze layer 12a of a thickness of 20-100mum is provided on a part of a width of 10-100mum of the crystalline glaze layer 12, and a heating resistor layer 13 is further provided on the noncrystalline glaze layer 12a. Furthermore, a gold electrode 14, an antioxidant SiO2 layer 15, and a wear-resistant Ta2O5 layer 16 are provided on these to obtain an objective base plate.</p> |
