Изобретение относитс  к керамическим огнеупорным материалам, которые могут примен тьс  в качестве износостойких носителей катализаторов высокотемпературных химических процессов.This invention relates to ceramic refractory materials that can be used as wear resistant catalyst carriers for high temperature chemical processes.

Известен огнеупорный материал на основе окиси алюм.ини .A refractory material based on aluminai oxide is known.

Дл  повышени  термической стойкости предлагаемый материал содержит, об. %:In order to increase thermal resistance, the proposed material contains about. %:

окись алюмини 90-95alumina 90-95

и, кроме того, нитевидныеand, moreover, filiform

кристаллы карбида кремни 5-105-10 silicon carbide crystals

Материал получают следующим образом. Дисперсный порошок окиси алюмини  смешивают с нитевидными кристаллами карбида кремни  в необходимом количестве. Полученную смесь подвергают гор чему прессовани-ю по следующему режиму: температура1500°СThe material is obtained as follows. The dispersed alumina powder is mixed with the silicon carbide whiskers in the required amount. The resulting mixture is subjected to hot pressing in the following mode: temperature 1500 ° C

давление150-200 кг/смpressure150-200 kg / cm
