99.99% seramiiki siri ike nano-alumina

1. N'ihi superplasticity nke nano-alumina ntụ ntụ, ọ na-edozi adịghị ike nke ngwa ngwa na-ejedebe site na obere okpomọkụ brittleness. N'ime ha, nano-aluminum oxy-carbide (SiC) nanocomposites bụ ndị a ma ama, na ike ha na-agbanwe agbanwe sitere na ceramics alumina nke otu-phase na-abawanye site na 300-400 MPa ruo 1 GPa, na mgbaji siri ike nke ihe na-abawanye site na ihe ndị ọzọ. karịa 40%.

2. Thermal nkwụsi ike: Mgbakwunye nke nano-alumina na mkpụrụ osisi seramiiki ọ bụghị nanị na-eme ka arụ ọrụ na-arụ ọrụ nke mkpụrụ osisi ahụ dịkwuo mma, ma na-eme ka nkwụsi ike nke okpomọkụ nke ihe na-emepụta ihe na-emepụta ihe na-eme ka ọ dịkwuo mma, na nkwụsị ọkụ na-eme ka ọ dịkwuo mma site na 2-3 ugboro.

3. Njupụta: Na usoro nke ntụ ntụ extrusion ịkpụzi, nano-α-Al2O3 ntụ ntụ nwere ike jupụta n'ime pores nke micron alumina ntụ ntụ, nke na-ebelata pore size; nrụgide ịkpụzi na-abawanye, na ọnụ ọgụgụ nke pores nwere ike ibelata, si otú ahụ na-emeziwanye Njupụta nke embrayo seramiiki na-eme ka njupụta na ihe ndị na-emepụta ihe nke alumina seramiki mgbe sintering.

4. Mbelata okpomọkụ na-ekpo ọkụ: mgbakwunye nke nano-a-Al2O3 na-akwalite ọrụ nkwụsịtụ ma na-enyere aka belata okpomọkụ okpomọkụ. Mgbe okpomọkụ na-ekpo ọkụ dị 1450 Celsius, ike mgbanwe na ike mgbaji na-eru nke kachasị.

5. Mgbakwunye nke obere nano-a-Al2O3 nwere ike imeziwanye ihe ndị na-emepụta ihe nke ọma. A na-agbaji seramiiki alumina na 1450 Celsius. Mgbe ego mgbakwunye bụ 10%, ike mgbanwe bụ 415 mPa na mgbaji siri ike bụ 4.1 MPa·m^1. /2.
