一、钨钼制品市场不断扩大 日本对钨钼制品的需要量从1987年起一反过去下降的趋势而转向升高。钨的最重要应用领域是硬质合金工业,1987年1—6月硬质合金工业所需的钨粉量784吨,比上一年度同期下降15%,而其他应用领域对钨粉的需要量却增加到2.6倍,达209吨。这当中主要用于集成电路陶瓷基板的喷镀,估计这一项年需要量大约为150吨。1987年1—6月进口的钨粉量为55吨,比上一年度同期下降了34%。
First, the tungsten and molybdenum products market continues to expand Japan’s demand for tungsten and molybdenum products since 1987, an anti-past trend of declining and turned higher. Tungsten is the most important application of the cemented carbide industry, from January to June 1987 cemented carbide industry required 784 tons of tungsten powder, down 15% over the same period the previous year, while other applications of tungsten powder needs But increased to 2.6 times to 209 tons. Among them, it is mainly used for thermal spraying of integrated circuit ceramic substrates, and the annual requirement is estimated to be about 150 tons. Tungsten powder imported from January to June 1987 was 55 tons, down 34% from the same period of last year.
