Abstract

PURPOSE:To produce sintered aluminum nitride in large quantities on an industrial scale at a low cost by sintering an AlN compact in a casing made of sintering plates produced by applying a paste containing W and AlN to the surface of graphite plates and sintering the product. CONSTITUTION:Paste 2 is prepared by compounding 100-30wt.% of W powder having particle diameter of <=10mum with 0-70wt.% of powder of sintered AlN crushed to particle diameter of <=100mum, adding an organic component such as binder and kneading the mixture. The paste 2 is applied to the surface of a graphite plate 1 by printing, brush coating, etc., to a thickness of >=10mum and sintered at 1800-2050 deg.C in nitrogen gas or argon gas to obtain a sintering member. A sintering casing shown in the drawing is formed by using the sintering members. The inner walls of two spaces of the casing have W-l-AlN layers 2. An Al compact 3 is placed in each of two spaces and the sintering casing is heated in nitrogen atmosphere (about 1900 deg.C under 1.1atm) for about 5hr to effect the sintering of the compact.

It is obtained by mixing at a ratio of 0 wt%, adding an organic component such as a binder, and kneading with a triple roll. Here, the W powder partially reacts with the graphite of the graphite plate 1 in the temperature range of 1800 to 2050 ° C. to obtain tungsten carbide (W
C) is formed to contribute to stable bonding between the graphite plate 1 and the surface treatment layer. On the other hand, the AlN sintered body powder is effective in preventing deformation such as warpage that occurs when the sintering reaction contracts during the sintering of the AlN molded body. Further, the weight of the sintering member can be reduced by increasing the ratio of the AlN sintered body powder to the W powder.
