Lithopone ipendi chena inoumbwa nemusanganiswa we barium sulfate ne zinc sulfide, inowanzo kuve muchikamu che1:1. Ichi chinhu chisina kugadzirwa chakagadzirwa kuburikidza nemakemikari anoshandiswa pakati pe barium sulfide ne zinc sulfate solutions, chinhu ichi chisina kugadzirwa chave chiri chinhu chikuru mumapurasitiki, mapurasitiki, uye zvizoro kwemaindasitiri kwemakore anopfuura zana, zvichikosheswa nekuchena kwayo kwakajeka, kujeka, uye kushanda kwayo zvakanaka.
Chimwe chezvinhu zvinonyanya kukosha zve lithopone isimba rayo guru rekuviga, iro rinokwikwidzana netitanium dioxide mune mamwe mashandisirwo, zvichiita kuti ive yakanaka pakupedzwa kusina kujeka. Inoratidza kuramba kwakanaka kune alkalis, kunyangwe iine hunhu hweacids, izvo zvinogona kuputsa chimiro chayo. Kusiyana nemamwe mavara, lithopone haishanduki ruvara kana iri muchiedza, zvichiita kuti igare kwenguva refu muzvigadzirwa zvekunze nemukati zvakafanana. Kusatora mafuta kwayo kushoma kunowedzerawo kushanda kwayo mumapendi neingi, zvichiita kuti ishandiswe zvakanaka uye ifambe zvakanaka.
Mukugadzirwa kwayo, mhinduro dzebarium sulfide dzakacheneswa uye zinc sulfate dzinosanganiswa, zvichiita kuti zvidimbu zve lithopone zvisapararire, izvo zvinozosefa, kugezwa, kuomeswa, uye kukuyiwa kuti zvisvike pahukuru hwakakodzera hwezvidimbu—zvinowanzo bva pa 0.5 kusvika 5 micrometers. Kukuya uku kunowedzera kupararira kwayo mumatrikisi akasiyana-siyana, kubva papendi dzakavakirwa pamafuta kusvika kumapurasitiki.
Indasitiri yekupeta inoshandisa lithopone zvakanyanya pakugadzira pendi dzemukati, ma primer, uye enamel, uko inopa hwaro hwechena hwakafanana uye inovandudza kufukidzwa. Mumapurasitiki, inoshanda semushonga wekuzadza uye kuchena muzvigadzirwa zvakaita semapaipi ePVC, matoyi, uye kurongedza, zvichivandudza chitarisiko uye kunaka kwechimiro. Mafomu ekuzora, akadai sehupfu hwechiso nemakirimu, anoshandisa lithopone kuti ipenye zvakanaka uye igone kuratidza chiedza, zvichiita kuti ganda rive rakatsetseka uye rakafanana.
