Ụlọ ọrụ semiconductor bụ ụlọ ọrụ sayensị na nkà na ụzụ na-apụta, nke dọtara mmasị dị ukwuu na afọ ndị na-adịbeghị anya, ọtụtụ ụlọ ọrụ amalitela ịbanye na ụlọ ọrụ semiconductor, na graphite aghọwo otu n'ime ihe ndị dị mkpa maka mmepe nke ụlọ ọrụ semiconductor. Semiconductors kwesịrị iji eletriki conductivity nke graphite, n'ihi na elu nke carbon ọdịnaya nke graphite, mma eletriki conductivity, n'ozuzu mkpa tụlee egosi bụ: urughuru size, okpomọkụ iguzogide, ịdị ọcha.
Ogo ọka dabara na ọnụọgụ ntupu dị iche iche, na nkọwapụta na-egosipụta na ọnụọgụ ntupu. Nọmba ntupu bụ ọnụ ọgụgụ oghere, ya bụ, ọnụ ọgụgụ nke oghere kwa square inch. N'ikwu okwu n'ozuzu, nọmba ntupu * oghere (micron) = 15000. The ibu ntupu ọnụ ọgụgụ nke conductive graphite, nta nke urughuru size, mma na lubrication arụmọrụ, nwere ike ji mee ihe na ubi nke lubricating ihe mmepụta. The urughuru size eji na semiconductor ụlọ ọrụ kwesịrị nnọọ mma, n'ihi na ọ dị mfe iji nweta nhazi nkenke, elu compressive ike, na dịtụ obere ọnwụ, karịsịa maka sintering ebu, na-achọ elu nhazi ziri ezi.
Nkesa nha urughuru, dị ka: ntupu 20, ntupu 40, ntupu 80, ntupu 100, ntupu 200, 320 ntupu, 500 ntupu, 800 ntupu, 1200 ntupu, 2000 ntupu, 3000 ntupu, 5000 ntupu, 5000 ntupu, 5000 ntupu. kacha mma nwere ike 15,000 mesh.
Ọtụtụ ngwaahịa na ụlọ ọrụ semiconductor kwesịrị ịdị ọkụ na-aga n'ihu, iji gbatịa ndụ ọrụ nke ngwaọrụ ahụ, nke na-achọ graphite na-eduzi iji nwee ihe ndị a: ntụkwasị obi dị mma na nguzogide mmetụta okpomọkụ dị elu.
Ihe ndị a chọrọ maka mmepụta graphite na ụlọ ọrụ semiconductor bụ: ịdị ọcha dị elu, ọ ka mma, karịsịa ngwaọrụ graphite na-emetụ n'etiti abụọ ahụ, ọ bụrụ na ha nwere ọtụtụ adịghị ọcha, ha ga-emerụ ihe semiconductor. Ya mere, anyị kwesịrị ịchịkwa ịdị ọcha nke graphite conductive, anyị kwesịkwara iji graphitization dị elu na-emeso ha iji belata ọkwa isi awọ.
