制造SnO_2和NiO气敏材料时,SnO_2是采用SnCl_4以NH_4OH沉淀制得的,NiO是采用Ni(NO_3)_2CO_3沉淀的方法制成的。以上两种材料经过洗涤、干燥、分解、灼烧,最后制成相应的敏感材料。 上述二种材料为基体,加入适当的掺杂剂如Pd、In、Li等粘合剂(Al_2O_3苏州土)等在玛瑙钵中仔细研磨呈浆糊状,以直热式烧结型元件制造工艺制成珠形元件(直径为小φ0.5～1
When manufacturing SnO 2 and NiO gas sensitive materials, SnO 2 is prepared by precipitation of SnCl 4 with NH 4 OH, and NiO is prepared by precipitation with Ni (NO 3) 2 CO 3. The above two materials after washing, drying, decomposition, burning, and finally made the corresponding sensitive material. The above two kinds of materials as the matrix, adding appropriate dopants such as Pd, In, Li and other adhesives (Al 2 O 3 Suzhou soil) and other agate mortar carefully ground to paste, with direct thermal sintering type component manufacturing process Bead-shaped components (small diameter φ0.5 ~ 1
