FIELD: construction element for microwave muffle furnace. ^ SUBSTANCE: claimed construction element is made from radiation absorbing environment friendly ceramic material, which makes it possible to achieve high temperature for short period and doesn't release destructive gaseous compounds during heating. Heater for microwave furnace is obtained by mixing of silicium carbide or modified silicium carbide with grade fineness of 200-500 mum or 80-100 mum, respectively, and leucoxene concentrate with grade fineness of 80-250 in ratio 14-19:1-6, wherein said leucoxene concentrate is reprocessing product of titaniferous oil-bearing ore with organic binder, followed by compaction and two-step thermal treatment in oxidative atmosphere. ^ EFFECT: increased maximum working temperature achieved within short period. ^ 2 ex, 2 dwg |
