Composite powder material, composite powder material paste, print head for laser printer, and thermal print head
The invention relates to a composite powder material, a composite powder material paste, a print head for a laser printer, and a thermal print head. Provided is a composite powder material capable offorming a coating layer having good wear resistance and thermal conductivity, the composite powder material being sufficiently sintered at 830 DEG C or lower, having little burden on the environment,and being free from significant foaming even when a silicon carbide powder is contained during calcination. The composite powder material contains glass powder, silicon carbide powder and aluminum oxide powder, the glass powder is represented by mol% on the basis of an oxide and contains 31%-42% of SiO2, 16%-26% of B2O3, 2%-10% of ZnO, 20%-30% of CaO, 1%-10% of BaO, 1%-10% of SrO and 1%-10% of Al2O3. The volume ratio (silicon carbide powder/(aluminum oxide powder + silicon carbide powder)) of the content of the silicon carbide powder to the total content of the silicon carbide powder and the aluminum oxide powder is 1-65%.
本发明涉及复合粉末材料、复合粉末材料糊、激光打印机用的打印头和热敏打印头。本发明提供在830℃以下烧结充分进行、对环境的负荷少且即便含有碳化硅粉末在煅烧时也没有明显的发泡、能够形成具有良好的耐磨损性、热导率的被覆层的复合粉末材料。该复合粉末材料含有玻璃粉末、碳化硅粉末和氧化铝粉末，上述玻璃粉末以氧化物基准的摩尔％表示，含有31～42％的SiO2、16～26％的B2O3、2～10％的ZnO、20～30％的CaO、1～10％的BaO、1～10％的SrO、1～10％的Al2O3，碳化硅粉末的含量与碳化硅粉末和氧化铝粉末的合计含量的体积比(碳化硅粉末/(氧化铝粉末+碳化硅粉末))为1～65％。
