Said metal nitride is prepared through mixing the aqueous soltuion of nitrate or sulfate of A with the aqueous soltuion of Cr, Mo or W acid or one of their ammonium salts, coprecipitation or impregnation to obtain load-type or non-load-type dual-component metal salt or compound oxide, then pass in NH3, sequentially heating and azotizing at 600-750 deg.C.

该金属氮化物是由含A过渡金属元素的硝酸盐或硫酸盐水溶液与Cr、Mo或W酸或者Cr、Mo或W酸铵水溶液混合，通过共沉淀法或浸渍法制成负载型或非负载型双组元金属盐或复合氧化物，再将双组元金属盐或复合氧化物通NH3进行程序升温，至最终氮化温度600～750℃下进行反应而制得。

Te burning synthesis process of nitride is suitable mainly for preparing beta-SiN.

与其它氮化物合成方法相比，静态氮气中直接氮化的合成方法具有节省资源和环境友好的优点。

Nitrogen is inert except when heated to very high temperatures, where it combines with some of the more active metals, such as lithium and magnesium, to form nitrides.

一般情况下，氮是不活泼的的。当加热到非常高的温度时它会同更加活泼的金属，如锂和镁反应生成氮化物。

Nitrogen from the gas is introduced into the steel, forming very hard nitrides that are finely dispe

氮的气体引入钢铁，很难形成氮化物，这些细分散通过表面金属。
