SiC pin trays maka usoro etching ICP na ụlọ ọrụ LED

Nkọwa dị mkpirikpi:

Silicon carbide bụ ụdị ceramik ọhụrụ nwere arụmọrụ dị oke ọnụ yana akụrụngwa akụrụngwa mara mma. N'ihi njirimara dị ka ike dị elu na ike siri ike, oke okpomọkụ na-eguzogide, nnukwu okpomọkụ conductivity na chemical corrosion resistance, Silicon Carbide nwere ike ọ fọrọ nke nta ka ọ ghara iguzogide ọgwụ niile. Ya mere, a na-eji SiC eme ihe na ngwuputa mmanụ, kemịkalụ, igwe na ikuku, ọbụna ike nuklia na ndị agha nwere ihe ha chọrọ na SIC.

Isi atụmatụ:

1. Nguzogide oxidation dị elu:

Nguzogide oxidation ka dị ezigbo mma mgbe okpomọkụ dị elu dị ka 1600 C.

2. Nnukwu ịdị ọcha: nke a na-eme site na ntinye ikuku kemịkalụ n'okpuru ọnọdụ chlorination dị elu.

3. Nguzogide nbibi: elu ike, kọmpat elu, ezigbo ahụ.

4. Nguzogide corrosion: acid, alkali, nnu na organic reagents.
