FOR IMMEDIATE RELEASE


             NL REPORTS SHARPLY INCREASED FIRST QUARTER EARNINGS
                        AND GAIN ON SALE OF RHEOX UNIT


HOUSTON, TEXAS - April 17, 1998 - NL Industries,  Inc. (NYSE:NL) reported income
from  continuing  operations for the first quarter of 1998 of $16.3 million,  or
$.32 per  basic  share  and $.31 per  diluted  share,  compared  to a loss  from
continuing operations in the first quarter of 1997 of $40.2 million, or $.79 per
basic and diluted share.  The 1997 results include a $30 million noncash charge,
or $.59 per share,  related to the adoption of the AICPA's Statement of Position
No. 96-1, "Environmental Remediation Liabilities."

Operating income of Kronos' titanium dioxide pigments  ("TiO2")  business in the
first  quarter  of 1998 was $39.4  million,  $30.7  million  more than the first
quarter of 1997 on higher TiO2 selling prices,  improved  production  volume and
record sales  volume.  Kronos' first quarter sales volume was 2% higher than the
first quarter of 1997. Kronos' average TiO2 selling prices for the first quarter
of 1998 were 17% higher  than the first  quarter of 1997 and 5% higher  than the
fourth quarter of 1997. J. Landis Martin, President and Chief Executive Officer,
stated,  "TiO2 prices have continued to increase since early 1997, and we expect
to realize further increases during the balance of 1998. We believe the industry
is in the early stage of a strong recovery and NL, with its increased  liquidity
and lower debt, is well positioned to participate in it."

The Company sold its Rheox specialty chemical operations for $465 million in the
first  quarter  of 1998,  including  $20  million  attributable  to a  five-year
agreement by the Company not to compete in the  rheological  products  business.
The Company  recognized an after-tax gain of  approximately  $285 million on the
sale of this business segment. The after-tax proceeds of about $384 million have
been used to reduce  outstanding  indebtedness by approximately $171 million and
the  balance is  expected to be used to invest in  additional  TiO2  capacity or
further reduce outstanding indebtedness. The Company's net debt (total debt less
cash and cash  equivalents)  declined  from $652 million at December 31, 1997 to
$218 million at March 31,  1998.  As a result of the sale,  Rheox's  results are
reported as discontinued  operations.  The  extraordinary  item in 1998 resulted
from the early  extinguishment  of debt,  primarily $117 million of Rheox's term
loan and  approximately $11 million of the Company's 13% Senior Secured Discount
Notes.  Net income for the first quarter of 1998 was $301 million,  or $5.80 per
diluted  share,  compared  to a net loss in the first  quarter  of 1997 of $35.7
million, or $.70 per diluted share.



NL  Industries,  Inc. is a major  international  producer  of  titanium  dioxide
pigments.

The statements in this release relating to matters that are not historical facts

materially from those forecasted or expected.
