Isticmaalka
Ammonium hydrogen difluoride waa cad oo crystalline ah oo loo isticmaalo warshado kala duwan. Hoos waxaa ku qoran hordhac kooban oo ku saabsan isticmaalkeeda:
- Warshadaha Semiconductor-ka: Waxaa loo isticmaalaa sidii wakiil wax lagu qoro oo loogu talagalay wafer-ka semiconductor-ka iyo soo saarista filimada khafiifka ah. Aayooyinka fluoride-ka ee ay sii deyso waxay gacan ka geystaan beddelidda astaamaha dusha sare ee walxaha, taas oo muhiim u ah habaynta saxda ah ee aaladaha semiconductor-ka.
- Warshadaha Muraayadda: Waxay u adeegtaa sidii wakiil sawir galaas ah, oo inta badan loo isticmaalo iyadoo lala kaashanayo hydrofluoric acid si loo xoojiyo saameynta sawir-qaadista. Waxa kale oo loo isticmaali karaa daawaynta dusha sare ee silicon - xaashida birta ah, waxayna ku lug leedahay soo saarista galaas gaar ah, sida galaas leh iska caabin heerkul sare ama falcelin kiimiko oo gaar ah.
- Habaynta Birta: Waxaa loo isticmaalaa sidii dareere loogu talagalay beryllium-ka birta iyo daaweynta dusha sare ee xaashida birta ah ee silicon. Warshadaha electroplating-ka, waxay dedejin kartaa falcelinta daxalka ee dusha sare ee birta, taasoo ka dhigaysa electroplating-ka mid isku mid ah oo adag.
- Kiimikada Kiimikada: Waxaa loo isticmaalaa sidii falgal kiimiko ah oo ku saabsan falgallada kiimikada iyo tijaabooyinka kala duwan. Waxa kale oo loo isticmaali karaa in lagu diyaariyo fluoride-ka birta iyadoo la falgalayo oksaydhyada birta ama biraha, waxayna u adeegtaa sidii isha ugu muhiimsan ee ion-yada fluoride-ka codsiyada warshadaha iyo falanqaynta badan.
- Isticmaalo Kale:Warshadaha wax soo saarka dhoobada iyo magnesium-ka, waxay door muhiim ah ka ciyaartaa habka wax soo saarka. Waxa kale oo loo isticmaalaa nadiifinta iyo nadiifinta quudinta kuleyliyaha - nidaamyada biyaha iyo nidaamyada soo saarista uumiga, iyo daaweynta aashitada ee dhagaxyada ciidda ee saliidda.
