Urupapuro rudapfa amasasu (isahani idapfa amasasu)ni igice cy'ingenzi cy'ibikoresho bidashobora gutwarwa n'amasasu. Muri iki gihe, ibikoresho bya silikoni karubide na alumina nyinshi ni byo bikoresho bibiri bya silikoni bikoreshwa cyane ku isoko. Kubera ko inzira yo kudatwarwa n'amasasu iba mu gihe gito cyane, ibikoresho bidashobora gutwarwa n'amasasu bisaba imiterere myinshi, nko kuba ubwinshi, porosity, ubukana, gukomera kwa fracture, elastic modulus, umuvuduko w'ijwi n'imbaraga za mekanike, nibindi.
Urupapuro rwa alumina rwa Chemshun rukozwe mu ifu ya alumina nziza cyane nk'igikoresho cy'ingenzi. Ubuziranenge bwa α-Al₂O₃ burenga 99%, ubucucike ni ≥3.9g/cm³, porosity iri hafi ya zeru, kandi igipimo cyo kwinjiza amazi ntikirenga 0.02%. Ubukomere bushobora kugera hejuru ya HRA88, ari na cyo gikoresho cya mbere gikoreshwa mu gushushanya ibumba ridashobora amasasu. Igipimo cyo gupima imbunda kirenze urwego rwa 3 rw'Abanyamerika. Muri icyo gihe, kandi ihura n'ibyo abakiriya bakeneye ku gushushanya ibumba ridashobora amasasu rya silikoni. Ubucucike ni ≥3.1g/cm³, ubukomere ni ≥HRA92, kandi igipimo cyo gupima imbunda gishobora kugera ku rwego rwa 4 rw'Abanyamerika.
Ingano y'urupapuro rwa keramike rwa chemshun alumina rudapfa gutwikirwa n'amasasu ni 50 * 50 * 10 mm na 50 * 25 * 10 mm, naho ingano isanzwe ya keramike ya silicon carbide ni 250 * 300 mm. Abakiriya bafite ibindi bisobanuro kandi bashobora kwemera guhindura ibintu.
