• Kurovedzwa Kwepfuma:

  1. Kuchena: Kuchena kwakakosha indekisi yegirazi yequartz. Izvo zvirimo zveSiO2 mune zvakajairika silika girazi zvinopfuura 99.99%. Izvo zvirimo zveSiO2 mune yakachena yakachena synthetic quartz girazi iri pamusoro pe99.999%.
  2. Optical kuita: Inofananidzwa neyakajairika silicate girazi, iro rinoonekera girazi requartz ine yakanakisa mwenje kubvumidzwa pane iyo yakazara wavelength bhendi. Munharaunda ine infrared uye inoonekwa yechiedza chakatarisana, iko kutariswa kwegirazi re quartz kuri nani pane girazi rakajairwa. Mune iyo ultraviolet spectral dunhu kunyanya ipfupi wave ultraviolet spectrum, iyo girazi re quartz iri nani kupfuura imwe.
  3. Kupisa kupisa: Iko kupisa kweiyo quartz girazi kunosanganisira kupisa kuramba, kudziya kwakatsiga, kusagadzikana patembiricha yakanyanya, chaiyo kupisa uye kudziya kwekupisa, crystalline zvivakwa (inozivikanwawo sekuti crystallization kana kukwana) uye kwakanyanya tembiricha kusiyanisa. Iyo quartz girazi rinopisa rekuwedzera kuwedzera iri 5.5 × 10-7cm / cm ℃ se1 / 34 yemhangura & 1/7 ye borosilicate. Hunhu uhwu hunoshandiswa mumunda wekuona weiyo lens yemaziso, hwindo repamusoro uye chimwe chigadzirwa chinoda kunzwisisika pakuchinja kwemafuta kusvika padiki. Quartz girazi sezvo coefficient yekuwedzera iri diki, ine yakanyanya kupisa kupisa girazi, girazi rinoonekera re quartz muchoto pa1100 ℃ pasi pekupisa maminetsi gumi nemashanu, uyezve mumvura inotonhorera, iyo inogona kumira 15-3 macircuit pasina kubvaruka. Nzvimbo inodzikamisa yegirazi yequartz yakakwira kwazvo segirazi regirazi rinoonekera iri 5 ℃, saka tembiricha yekushandisa isingagumi yequartz chiridzwa chiri 1730 ℃ -1100 ℃, 1200 ℃ inogona kushandiswa munguva pfupi.
  1. Kemikari kuita: Quartz girazi yakanaka acid zvinhu. Kugadzikana kwayo kwemakemikari kwakaenzana neanokwana makumi matatu easidhi inoshingairira zvedongo, ka30 kanikiki chromium chiwanikwa uye zvakajairika zvedongo pakakwirira tembiricha uye yakakwenenzverwa iasidhi yekushandisa kukwirira kwakanyanya kunonyanya kukosha kunze kwehydrofluoric acid uye 150-phosphate. Girazi requartz harigone kukanganiswa nekumwe kukukurwa kweasidhi, kunyanya sulfuric acid, nitric acid, hydrochloric acid uye aqua regia patembiricha yakakwira.
  1. Zvokuimba zvinhu: Iko michina yezvinhu zvegirazi yequartz yakafanana neyawo mamwe magirazi, uye simba ravo rinoenderana nekutsemuka kudiki mugirazi. Modulus yekusununguka, kusimba kwesimba uye simba rinoshanduka rinowedzera nekuwedzera tembiricha, kazhinji inosvika pakakwirira pa1050-1200 ℃. Yakakurudzirwa pamashandisirwo emushandisi nesimba rekumanikidza ndi1.1 * 109Pa uye ensile simba 4.8 * 107Pa.
  1. Imba yemagetsi: Quartz girazi rine chete maratidziro akaenzana ealkali simbi ioni inova murombo conductor. Kurasikirwa kwaro dielectric idiki kwazvo kune ese ma frequency. Sevadziviriri vakasimba, ayo emagetsi uye emuchina zvivakwa zviri nani kwazvo kupfuura izvo zvezvimwe zvinhu. Pakazara tembiricha, iyo yemukati kurwisa yakajeka yegirazi quartz girazi iri 1019ohm cm, yakaenzana kusvika 103-106 nguva dzegirazi rakajairika. Iko kuputira kwekushomeka kwegirazi rinoonekera re quartz pane chaiyo tembiricha iri makumi mana emazana volts / mm.
  1. Kumanikidza kurwisa: Pfungwa, iyo tensile simba iri rakanyanya kukwirisa kupfuura mamirioni mana mapaundi pasikweya inch, girazi rekupenya rakaenzana ukobvu hwesimba rinopesana-simba i4 ~ 3 nguva dzegirazi rakajairika uye kukotama simba kuri 5 ~ 2 nguva dzegirazi rakajairika. Kana girazi rikakanganiswa nechisimba chekunze, marara anoverengeka anova kona yekudzivirira iyo inoderedza kukuvadza kumuviri wemunhu.
  1. Homogeneity: Iyo makemikari anowirirana anoenderana neyakaitika mamiriro zvichikonzera kubvisa kutsemuka, matema, kusachena, kusagadzikana, kushanduka uye zvichingodaro. Mune chivakwa chemuviri uye chemakemikari, ine yakaenzana-chikamu chikamu kuti ive nechokwadi chekuita kwakanaka.
