Vermiculite ndi mchere wa hydrous phyllosilicate womwe umakula kwambiri (kutulutsa) ukatenthedwa. Exfoliation imachitika pamene mchere watenthedwa mokwanira. Ndizopepuka kwambiri ndipo zimasakanikirana mosavuta ndi ma mediums ena. Vermiculite imapangidwa ndi nyengo kapena kusintha kwa hydrothermal kwa biotite kapena phlogopite.

Cenosphere ndi gawo lopepuka, lopanda kanthu lomwe limapangidwa makamaka ndi silika ndi aluminiyamu ndipo limadzazidwa ndi mpweya kapena mpweya wa inert, womwe umapangidwa ngati chinthu choyaka malasha pamafakitale opangira magetsi. Mtundu wa cenospheres umasiyana kuchokera ku imvi mpaka pafupifupi woyera ndipo kachulukidwe kake ndi pafupifupi 0.4-0.8 g/cm3 (0.014–0.029 lb/cu in), zomwe zimawapangitsa kuti azisangalala kwambiri.

Ma cenospheres ndi olimba komanso olimba, opepuka, osalowa madzi, osavulaza, komanso oteteza. Izi zimapangitsa kuti zikhale zothandiza kwambiri pazinthu zosiyanasiyana, makamaka ma fillers.

Makhalidwe a Cenosphere: Tinthu tating'onoting'ono, tinthu tating'onoting'ono, topepuka, mphamvu yayikulu, kukana kuvala, kukana kutentha, kutsekemera kwamafuta.

Wollastonite ndi mchere wa calcium inosilicate (CaSiO3) womwe ungakhale ndi chitsulo chochepa, magnesium, ndi manganese m'malo mwa calcium. Wollastonite ndi mchere wachilengedwe wokhala ndi mikhalidwe yambiri yapadera. wakhala mmodzi wa anthu ambiri ntchito fillers ntchito. Wollastonite imatha kukonza magwiridwe antchito azinthu, monga mapulasitiki, utoto ndi zokutira, zomangira, mikangano, zoumba, ndi mafakitale azitsulo.

Lava mwala & Pumice

Mwala wa lava, womwe umadziwikanso kuti volcanic rock, pumice stone, kachulukidwe kake ndi pafupifupi 0.4-0.85g/cc, kutulutsa kowala kwa galasi la acidic volcanic rocks. Amadziwika ndi kulemera kopepuka, mphamvu yayikulu, kukana kwa asidi, kukana kwa dzimbiri, komanso kusaipitsa, osatulutsa ma radio ndi zina zotero. Ndi abwino zachilengedwe, zobiriwira, chilengedwe mankhwala.

Pumice ndi yopepuka kwambiri, yopepuka komanso yonyezimira ndipo imagwiritsidwa ntchito pomanga ndi kukongola. Amagwiritsidwanso ntchito ngati abrasive, makamaka popukuta ndi ma jeans otsuka mwala. Pali kufunikira kwakukulu kwa pumice, makamaka kusefa kwamadzi, kusunga mankhwala otayira, kupanga simenti, ulimi wamaluwa ndi malonda a ziweto.

Vermiculite ndi mchere wa hydrous phyllosilicate womwe umakula kwambiri (kutulutsa) ukatenthedwa. Exfoliation imachitika pamene mchere watenthedwa mokwanira.

Mica ndi mchere wachilengedwe wopangidwa ndi potaziyamu, aluminium, chitsulo, madzi ndi magnesium. Mica imachitika mwachilengedwe ndipo imasonkhanitsidwa kutengera mchere wa silicate. Amapangidwa kukhala mbale yopyapyala kapena mawonekedwe a pepala, okhala ndi zolemba zosiyanasiyana zamchere komanso mawonekedwe wamba. Mica imatha kukhala yolimba komanso yolimba ngakhale kutentha kwambiri, ndichifukwa chake mica ndiyoyenera kugwiritsidwa ntchito pachinyezi komanso kutentha kwambiri. Mineral mica ili ndi mayamwidwe osiyanasiyana a 2% mpaka 5%.

Calcined kaolin/Kaolin Clay, amatchedwanso China Clay, ndi ufa woyera sanali pulasitiki zakuthupi. Dzina loti "kaolin" limachokera ku "Gaoling" Kaolinite ali ndi kutsika kochepa-kutupa komanso mphamvu yotsika ya cation-exchange. Ndi mchere wosanjikiza wa silicate. Ndi mchere wofewa, wapadziko lapansi ndi woyera, wopangidwa ndi mankhwala a aluminiyamu silicateminerals monga feldspar.

Calcined China Clay imagwiritsidwa ntchito muzoumba, kupanga mapepala, kupenta, zida zokanira ndi labala. Ndikofunikira muzitsulo zotayira ndi mipando, matupi otchinjiriza matenthedwe, matupi okulitsa otsika, kapangidwe ka ceramic kokwanira.

Perlite ndi galasi lamapiri la amorphous lomwe lili ndi madzi ochulukirapo, omwe amapangidwa ndi hydration ya obsidian. Zimachitika mwachibadwa ndipo zimakhala ndi katundu wachilendo wofutukuka kwambiri zikatenthedwa mokwanira. Ndi mchere wamafakitale komanso chinthu chamalonda chomwe chimathandiza chifukwa chochepa kwambiri pambuyo pokonza.

Perlite pops ikafika kutentha kwa 850-900 °C (1,560-1,650 °F). Madzi otsekeredwa m'mapangidwe a zinthuzo amatuluka ndikuthawa, ndipo izi zimapangitsa kuti zinthuzo zichuluke mpaka 7-16 nthawi yake yoyambirira. Zowonjezereka ndizoyera zoyera, chifukwa cha kunyezimira kwa thovu lotsekeredwa. Perlite wosatambasuka ("yaiwisi") ali ndi kachulukidwe kochulukira pafupifupi 1100 kg/m3 (1.1 g/cm3), pomwe perlite wokulirapo amakhala ndi kachulukidwe kochulukira pafupifupi 30-150 kg/m3 (0.03–0.150 g/cm3).
