Dabarun samarwa da abubuwan da ke hana ruwa gudu
Samar da abubuwan yumbu masu ƙima na boron nitride ya haɗa da ainihin haɗin foda, siffata, and sintering strategies. h-BN is commonly produced through hot pushing or stimulate plasma sintering, while c-BN requires high-pressure, high-temperature (HPHT) methods to maintain its cubic phase. Accomplishing dense, defect-free BN ceramics remains a challenge as a result of the product’s inherently low self-diffusivity and propensity towards porosity. Ingredients such as yttria or alumina are frequently introduced to improve densification without endangering thermal or electric performance. Recurring research concentrates on additive production, nanostructuring, and crossbreed compounds to increase the variety of viable geometries and performances.
