Why 170+ W/mK AlN datasheets don't guarantee reliability in SiC power modules. This article reveals the hidden risks that surface during validation—batch inconsistency, flatness variation, density uniformity issues, and metallization mismatches. Learn what experienced engineering teams actually look for in AlN substrate suppliers: batch repeatability, transparent QC, and engineering-stage support.

Beryllium oxide (BeO) ceramics, with their unique combination of properties—high thermal conductivity, high electrical insulation, high-temperature resistance, and excellent nuclear properties—have secured important applications in these fields. Despite challenges in toxicity management, their comprehensive performance advantages ensure they retain significant research and application value under

Alumina grinding balls have become a popular grinding medium in the pharmaceutical industry due to their ultra-high hardness, excellent wear resistance, chemical inertness, and high purity, making them ideal for micronizing active pharmaceutical ingredients, formulation preparation, and biopharmaceutical research and development.

Is e meatailteachadh ceirmeach an dòigh air còmhdach meatailt fìor ghleidheil a thasgadh air uachdar ceirmeag. Is e ceum deatamach a tha seo leis gu bheil ceirmeag gu tur mì-fhliuch ri solder. Tha an còmhdach meatailte gan dèanamh so-ruigsinneach, a 'toirt seachad a' bhunait riatanach airson ceanglaichean làidir ceirmeag-gu-meatailt a chruthachadh.

Tha neart teirmeach àrd aig bùird cuairteachaidh clò-bhuailte traidiseanta le cridhe meatailt (MCPCBn) mar thoradh air an ìre de insulation polymer a tha a dhìth eadar na sreathan meatailt agus cuairteachaidh, gan dèanamh nas comasaiche air coinneachadh ri feumalachdan sgaoilidh teas LEDan àrd-chumhachd agus ultra-chumhachd. An coimeas ri sin, bidh fo-stratan ceirmeag a’ cothlamadh insulation agus giùlan teirmeach, a’ cur às do strì teirmeach eadar-aghaidh

Tha Alumina na ainm nas trice airson aluminium oxide (Al2O3). Is e ceirmeag theicnigeach seasmhach a th’ ann le measgachadh air leth de fheartan meacanaigeach is dealain. Tha e freagarrach airson raon farsaing de thagraidhean gnìomhachais.

Is e ceirmeag synthetigeach sòlaimte a th’ ann am Boron nitride a thig ann am pùdar agus cruth cruaidh. Tha Boron nitride na stuth air leth sònraichte air sgàth a fheartan sònraichte, a tha a’ toirt a-steach comas teas àrd, giùlan teirmeach air leth, furasta innealachadh, lubricity, seasmhach dielectric ìosal, agus neart dielectric leasaichte.

Tha alùmanum nitride na stuth feumail ann an grunn thagraidhean gnìomhachais air sgàth a fheartan ceimigeach agus corporra.Ach, ann an saothrachadh, tha alùmanum nitride air a sgaradh sa mhòr-chuid ann an dà sheòrsa stèidhichte air a’ phròiseas sintering: alùmanum nitride sintered gun chuideam agus alùmanum nitride le cuideam teth. Tha feartan agus tagraidhean an dà roinn seo gu math eadar-dhealaichte.

Is e boron carbide aon de na stuthan as làidire agus as seasmhaiche a tha ri fhaighinn ann an àrainneachd an latha an-diugh, far a bheil coileanadh, èifeachdas agus fad-beatha cudromach. Tha e ainmeil airson a sheasmhachd teirmeach iongantach, inertness ceimigeach, agus cosg-èifeachdas, agus tha e air a bhith na mhaoin luachmhor ann an grunn ghnìomhachasan, a’ gabhail a-steach saothrachadh agus dìon.

Taobh a-staigh teaghlach Kovar, is e 4J29 an stuth àbhaisteach agus air a mholadh airson a bhith a’ frasadh ceirmeag àrd-alùmana, a’ toirt seachad deagh chothromachadh de choileanadh, cosgais, agus eisimeileachd. Tha 4J33/34 na leasachadh coileanaidh airson tagraidhean sònraichte a dh’ fheumas teòthachd obrachaidh nas àirde no feartan neo-magnetic teann. Brasadh Kovar le ceirmeag alumina, le taic bhon teirm aca
