Muri Kanama, igiciro rusange cy’ifu ya silicon nitride (Si: 48-52%, N: 30-33%, Fe: 13-15%), igiciro rusange cy’isoko cyari amafaranga 8000-8300 / toni, cyari hafi amafaranga 1000 / toni hejuru ugereranije n’umwaka watangiye, kwiyongera hafi 15% ugereranije n’umwaka ushize. (Ibiciro byavuzwe haruguru nibiciro byimisoro-nganda).

Bitewe n'izamuka ryinshi ry'igiciro cy'ibikoresho fatizo bya silicon icyuma muri uyu mwaka, bigatuma ibiciro by’umusaruro wa silicon nitride ya silicon, bigera kuri 75B icyuma cya silicon, urugero, igiciro rusange kiriho ubu hafi ya 8500-8700 yu / toni, kandi mu ntangiriro zuyu mwaka igiciro cy’amafaranga 7000 / toni. Igiciro cy'umusaruro w'ibikoresho fatizo cyazamutse cyane, kandi igiciro cy'ifu ya silicon nitride y'icyuma cyahatiwe kuzamuka.

Hamwe n'izamuka ry'ibiciro by'ibikoresho fatizo byinshi, abakora ibikoresho bya diyama mu gihugu bitera ikibazo gikomeye, kandi inganda nyinshi zagombaga kuzamura ibiciro.

Byumvikane ko inganda zitanga umusaruro muri iki gihe mu Bushinwa zihagaze neza, zitangwa bihagije, ariko zikagira ingaruka ku gukumira no kurwanya icyorezo, ibinyabiziga bitwara abantu ni bike, ibiciro by’imizigo nabyo biri hejuru ugereranije n’ibihe byashize, abakiriya bo hasi bagomba kwitegura hakiri kare.

Niba ukeneyediyama, ibiziga bya diyama, inkweto za diyama, isahani yo gusyanibindi, ikaze kutwandikira.
