Njirimara nke seramiki silicon nitride

1, nwere ike dị elu na oke okpomọkụ;

2, nnukwu mgbaji siri ike;

3, ike na-ehulata nke ọma;

4, iguzogide n'ibu ike ọgwụgwụ na creep;

5, ìhè - obere njupụta;

6, ike siri ike na iyi nguzogide;

7, nke ọma thermal ujo eguzogide;

8, mgbasawanye okpomọkụ dị ala;

9, ihe mkpuchi eletrik;

10, ezigbo mgbochi oxidation;

11, mma chemical corrosion eguzogide.

Silicon nitride ceramics nwere ọnụọgụ mgbasawanye ọkụ dị ala yana ịdị elu thermal conductivity, yabụ na ha nwere ezigbo nguzogide ujo.Silikoni nitride na-ekpo ọkụ na-ekpo ọkụ agaghị agbaji mgbe a kpochara ya ruo 1000 ℃ ma tinye ya na mmiri oyi.Na ọ bụghị oke elu okpomọkụ, silicon nitride nwere nnukwu ike na mmetụta na-eguzogide, ma n'elu 1200 ℃ ga-emebi na uto nke ojiji oge, nke mere na ike ya na-ebelata, ọzọ adịkarịghị ike ọgwụgwụ mmebi n'elu 1450 ℃, otú ojiji. nke Si3N4 okpomọkụ n'ozuzu adịghị gafere 1300 ℃.
