I.　Process　Introduction

Dissolve　wet　boric　acid　from　industrial　boric　acid　workshop　in　special　solvent　under　certain　conditions,　add　in　aid,　achieve　boric　acid　solution　through　precipitation　and　filtration,　and　then　achieve　high-purity　boric　acid　and　mother　liquid　through　cooling,　crystallization,　dehydrating,　washing　and　drying　under　certain　conditions　and　in　cycle　use.

II.　Technical　Advancement

It　is　proprietary　technology,　with　yield　97%,　product　purity　in　conformity　with　electronic　grade　standard,　short　process　flow,　free　of　heavy　crystallization,　little　equipment　investment　and　stable　product　quality.

III.　Market　Prospect

The　product　is　mainly　applied　in　electronics,　formation　foil,　electrolytic,　capacitance　and　other　industries,　which　can　be　also　used　as　chemical　reagent　for　chemical　analysis.　The　present　domestic　high-purity　boric　acid　output　is　almost　in　blank　space,　market　price　is　relatively　high,　and　the　prospect　is　optimistic.

IV.　Technical　Sources

Autonomous　research　and　development.

V.　Product　Quality　　　　

Item	Indicator	Item	Indicator
Boric　acid　　　　≥	99.5-100.8	Phosphate　≤	0.001
Water　insoluble　≤	0.0001	Calcium　　　　　　　≤	0.005
Sulfate　　　≤	0.0005	Arsenic　　　　　　　≤	0.0002
Chloride　　　≤	0.0001	Heavy　metal　　　≤	0.0005
Iron　　　　　　　≤	0.0005	Moisture　　　　　　　≤	0.5

VI.　Investment　Scale

Calculate　based　on　1000t/a,　the　equipment　investment　is　1.2　million　Yuan.

VII.　Environmental　Protection　

The　process　does　not　have　three　wastes　discharge,　without　causing　disadvantageous　environmental　impact.

VIII.　Economic　Benefits

Comprehensive　production　cost　is　7,500　Yuan/t,　and　factory　price　is　more　than　10,000　Yuan/t.

IX.　Form　of　Cooperation

Technical　transfer.　Taking　responsibility　for　process　flow　design,　supporting　equipment　of　standard　equipment,　non-standard　equipment　manufacture　design,　equipment is　plane　layout　design,　equipment　installation　design,　pipe　network　design,　equipment　installation　guidance,　equipment　commissioning,　production　commissioning,　training　for　production　engineers,　analysis　staff　and　technicians,　process　operation　specifications,　raw　material　and　product　analysis　method,　and　preparation　of　intermediate　control　analysis　method;　ensuring　output,　yield　and　quality　to　reach　the　standard;　and　undertaking　turn-key　projects.
